     Your fuel injection computer (DME) may output a code that indicates a faulty camshaft position sensor (CPS). This important sensor tells the car’s computer where the engine is in its rotation with respect to the combustion cycle. The DME takes the signals from the cam position sensor and crankshaft position sensor, and calculates when to fire the fuel injectors and spark plugs. If the camshaft position sensor is not operating properly, your car will run very erratically or perhaps not at all.

     Replacement of the sensor itself is quite easy. First, remove the VANOS solenoid to gain access to the sensor (see Photo 2 of Project 18). Then, using a 5-millimeter Allen wrench, remove the sensor’s retaining bolt. The sensor should pull out of its location in the cylinder head. That’s the easy part. The tough part is disconnecting the electrical connectors located underneath the intake manifold. If you have really skinny hands, you may be able to reach under the manifold and disconnect it. However, I had to first remove the intake manifold (see our intake manifold removal article).

     Alternatively, you may be able to reach in there once you disconnect and remove the oil filter housing. The housing attaches to the engine block with six bolts, but to access them you have to remove the alternator and alternator mounting bracket. Use a new gasket when you reinstall it. Even though this is a pain, it is much easier than removing the entire intake manifold. Now that you have a clear path, use a new O-ring when you install the new camshaft position sensor.

     If you are doing a number of projects that require access under the intake manifold, I recommend removing it. While you have access, you can replace the knock sensors (Photo 22 of Project 17), the VANOS oil line (Project 18), the crankshaft position sensor (Project 15), and a host of other hoses and sensors that are normally hidden underneath the intake manifold.

Shown here is the outside of the camshaft position sensor on a six-cylinder E36 engine. The inset shows a new O-ring installed into the head prior to sensor installation. Note the location of the VANOS oil line off to the right. The VANOS solenoid must be removed (Project 18) in order to reach the camshaft position sensor.

This photo shows the location of the camshaft position sensor on the E36 318 four-cylinder engine.
Figure
Figure 3
This photo shows the location of the camshaft position sensor on the E36 six-cylinder engine. As you can see, access to the electrical connector underneath the intake manifold is very difficult. Removing the oil filter housing will help, but you will still need long, skinny arms to reach in there and disconnect the harness. It may be easier to remove the intake manifold, particularly if you plan to replace other items such as the knock sensors.

Comments and Suggestions:
richelieu Comments: My 1998 528i will start but there is low power when on the gas,once it warms up and a soft sound clicks out then there is a summed correct power ..any ideas?
July 20, 2014
  Followup from the Pelican Staff: I would check fuel pressure, volume and quality. Also exhaust back pressure. - Nick at Pelican Parts  
Chris Comments: I have a 2000 328i 5 speed manual w/241,000. Car runs fine when started oold until engine is shut off. When restarted after a short time, car stalls when clutch is pushed in to shift. RPM gauge drops all the way down and the car stalls. I have to wait until it almost stalls from not shifting and then push in clutch to hopefully make the engine catch..works most times but is a big pain. Check Engine light is on...had it read, states it a camshaft position sensor. Does that go hand in hand with my problem?
July 8, 2014
  Followup from the Pelican Staff: Camshaft sensor can cause stalling. I would start there. - Nick at Pelican Parts  
just terry Comments: I just had work done on my 2006 325i bmw , one of the suggested repairs were to change cam sensor. Along with every thing else they suggested a total of 2,100.they said they couldn't find the leak they said ibhad and asked me to keep a look out for oil. Well here I am almost a moth later and now I have. Transmission maulfuction : can I possibly be from them changing the cam senor ?
July 6, 2014
  Followup from the Pelican Staff: I would think not. The cam sensor is not part of the transmission. - Nick at Pelican Parts  
Mike Comments: Hi my 2004 bmw 79k miles 325 just stopped in the middle of the street. The gas in the tank shows 37 miles to E. i pushed the car to the nearest gas station. I cranked it up turned on then went off. I repeatedly did this 4 more times. I then decided to fuel up and it turned on. Now I'm a little perplexed and dont really know what the diagnosis could be, any ideas
June 17, 2014
  Followup from the Pelican Staff: SOunds like you ran out of fuel. I would perform a fuel delivery system test. Check fuel pressure, volume and quality.
- Nick at Pelican Parts
 
Tazza Comments: Hi nick, I have have 2001 bmw e46 325i, problem with my car is sometimes when driving from standing position and right about to accerlate, the turns off and like wise when reversing. Doesn't happen often. Other times car runs perfect and has good response from the get go. Do you reckon it's a fuel issue or cam position sensor from what I've read online?
June 7, 2014
  Followup from the Pelican Staff: I have seen camshaft sensors cause this in the past. However, with no fault code or test results it's hard for me to help.



I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and pressure fuel, volume and quality. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.
- Nick at Pelican Parts
 
squidge Comments: Hi, I have a 2002 BMW 325ci. It is hard to start first thing in the morning. it will just crank over and over then will go. IT run ruff for a 10secs. I will start driving and it is fine. park it up then the same problem again.The warmer the engine and out side temperture the quicker it will start.If i get up in the morning leave the ignition onfor 10mins then try and start it will start up first time.
Thanks

spdfrk Comments: Great write up, thanks. I just did the job, would like to add:
1. To get the sensor all the way out, and get the new one in, I had to move the oil line to the vanos unit out of the way slightly - just very lightly loosen the banjo bolt that attaches the hose to the vanos, and rotate the hose to allow clearance to remove the sensor.
2. Being too lazy to even consider removing the intake, or even the oil filter housing, I found enough room to access the sensor connector was available after just removing the oil filter lid and filter. I had the kids try to unplug the old sensor and plug in the new one with their skinny arms/little hands first, but they were pretty useless. With the oil filter + lid removed I was able to do the job.

Clif Comments: Hi I have a 1999 BMW 323is E36 M52 with 95k miles on it. I recently replaced my head gasket and the car seems to run fine but my Check Engine Light came on and the codes read P1519 and P0740. P1519 is "Camshaft Position Actuator Bank 1" Does this mean the sensor needs to be replaced or could it be a different issue?
May 14, 2014
  Followup from the Pelican Staff: I would start by checking camshaft timing. if it is not correct, this code can set. - Nick at Pelican Parts  
Eric Comments: Hi I have a 1998 323 convertible with a 5 speed, Its run great since i got it 3 years ago but now its recently developed a bit of a problem. When I engage the clutch or stand in neutral I notice my once silky idle has a new unexplained roughness. Also when I pull from a low rpm it feels like the motor hesitates, almost as if the clutch were slipping or the engine has failed to ignite a cylinder. My issue is that no check engine light has come on to point me in the right direction. I'm thinking its something with the CPS or vanos the low end performance is just not what it used to be.

Thanks
May 8, 2014
  Followup from the Pelican Staff: Could be a vacuum leak, failing fuel pump or engine misfire. I would check spark, fuel and compression on all cylinders.
- Nick at Pelican Parts
 
Stev Comments: 2003 325XI

Replaced "air pump" and "control valve' due to "ses" light and code. Light is out now but the car is now behaving poorly at speed. At around 65 mph when accelerating to pass there is a "rumbling" and sort of "studdering" from what feels like the transmission. No problem when letting off the gas or when not in gear and running up rpm.
May 6, 2014
  Followup from the Pelican Staff: Is it a drivetrain vibration or engine misfire? You could a bad driveshaft or cv axle, or an engine miisfire. Have you checked for codes, again? - Nick at Pelican Parts  
Arturas Comments: Hello there , have bmw 520 e39 1996 model.240000 just changed pistons , piston rings etc... on the start car is building up rpms very slowly and then when it has 3 or 4 engine keeps taking more rpm but car is working against.I checked the faults and it was vanos and camshaftsensor. yesterday car went nuts , starting ok but when i use gas its working against , holding about 30 seconds on 5rpm and then drops to 0. car dies, same if you push on gas. checked plugs and coils seems ok. Please help :
April 30, 2014
  Followup from the Pelican Staff: I would check mechanical engine timing. It may off. Double check the crankshaft and camshaft alignment, and VANOS installation. -Nick at Pelican Parts  
Nick Comments: Nick, Nick here. I have a 97, 528i, 254k miles. I believe I have diagnosed the problem, but there's something that boggles my mind. I have had some issues with the overheating, I replaced the radiator, water-pump, belts, thermostat and a hose; it still overheated in a very bad way on the highway. To the point that there must have been 3 quarts of oil that pooled under my car. Long story shortened; my reservoir was cracked, that was where my coolant was going...duh. Now back to the mind being boggled. I suspected either a blown engine, or oil hose with all the lost oil or a blown head gasket. I didn't realize all the oil under the car, it was very early in the morning, and I was more concerned about all the idiots flying by in the HOV lanes. I tried to start the beema, no joy, that's when I noticed the stream of oil that couldn't stay inside the confines of the pool, streaming to the side of the highway. I added some oil and some water that following weekend; to my surprise it started right up, it ran sluggish for about a minute, than all appears well. I did a compression test, which seemed fairly normal. Boggled mind part again, the BMW starts up easy, runs sluggish for about 30 seconds, than off to work I go. One thing I noticed, even when the car is cold, I can open a bleeder valve, and alot of pressure is released, or I can remove the resevoir cap, and immediately water that is being held somewhere overflows the tank. One other thing I noticed when I first start the car, and it's still cool; I open a bleeder valve, the water comes out in a stream, than air for a second, than a stream etc etc etc, that's one of the reasons I believe it's a blown head gasket; the oil appears to be clear of water, and the coolant appears to be clear of oil; however, I did notice a very slight discoloratation of the oil on the oil filler cap. I'm thinking a head gasket replacement is in order, or is it time to put a fork in this car because of the amount of miles.
Thanks for your help and advice.
Nick

  Followup from the Pelican Staff: It does sound like the head gasket may have failed. I would have the cooling system tested for combustion gases. If CO2 is present, this will indicate a faulty gasket. You can also pressure test the cooling system. If the system does not hold pressure and there are no external leaks, you may have a faulty head gasket. - Nick at Pelican Parts  
eurolove Comments: Hello. I have a 1998 318i and the check engine light keeps coming on, then off. I had it scanned and it was for cam position sensors. Reset the code but would come on again randomly. If i just leave it, it will turn off by itself and then in 1 or more days it would come on again. it's been on and off for a month now. Should I look at getting it replaced?
April 29, 2014
  Followup from the Pelican Staff: I would check operation of the sensor that is setting the fault code, replace it if necessary. - Nick at Pelican Parts  
Davy Comments: Hi Nick
I have a 2001 330xi and had a check engine light come on about two months ago. Diagnostics read a cam shaft position sensor A. I cleared the code and drove the vehicle for three weeks until the check engine light appeared again and confirmed the previous fault code appeared a second time. The next day I went to drive the vehicle and it wouldn't start. The engine wants to turn over but just won't take that final step to engage the engine. Both the intake and exhaust cam shaft positioning sensors were replaced five months ago with new ones. Any suggestions as to what is going on?
April 25, 2014
  Followup from the Pelican Staff: Is the fault code for the camshaft sensor back? Have you checked fo fault codes? I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and pressure fuel, volume and quality. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.

md Comments: Hey Folks,
my 325 i is running fine except a service engine soon light that my friend said it showed a retarded timing bank one. Can anyone tell me what I am looking at as far in price. Thank so much.
April 10, 2014
  Followup from the Pelican Staff: Could be a faulty sensor or VANOS actuator. hat fault code was stored? - Nick at Pelican Parts  
Naz Comments: Hey, I got a 2002 bmw 330ci and did an oil change put in castrol part syntethic 10w 30, started it and had runing for like 5 minutes, them started it again and there was a knock in the back of the engine, I shut it off and then stated it again and it was the same, I looked under the oil cal tgere was yellow foam, maybe it had cheap oil in it from the previous owner before so it maybe mixed and causing this? Thank you let me know what to do
April 10, 2014
  Followup from the Pelican Staff: Mixing oil types will not cause engine knock or foaming. Over-full oil can cause foaming, knocking can be caused by poor lubrication or worn parts. - Nick at Pelican Parts  
Bull Comments: hi i have a e36 m42 motor thats over fueling iv checked my injectors n its fine could the cold start or cn it be the cam shaft sensor?
April 9, 2014
  Followup from the Pelican Staff: I would start by checking fuel pressure. Cam sensor is unlikely as the cause. - Nick at Pelican Parts  
Naz Comments: Hi I have a 2002 bmw 330ci e46, it takes me like 3 times to start it until it starts and then runs but it runs like it wants to die... I did have it sitting for like 3 months with no airbox, possibly something got into the system ? Thanks
April 6, 2014
  Followup from the Pelican Staff: Could be a disconnected sensor or a faulty camshaft sensor, fuel pump, etc. I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.

Coyney Comments: Got a 2006 325ti compact, recently bought.. Took it for an afternoon spin with a friend had to jam on the brakes to avoid someone jumping a stop and nearly topped it afterwards i opened the car up on the motorway and everything seemed fine, the car smelt and felt a bit hot but temperature gauge reads normal so i didn't think anything of it. However after refilling petrol at the station, i pulled out and noticed the temp rise really quickly until after about 1 minute and it hit red and i pulled over and turned her off.

I let her cool down and checked the coolant but it seemed fine didnt check radiator pipes. Started it up again and straight away the gauge started to raise again when idle and moving. When idle the revs seem to rise and fall when idle for a while then stopped again. At first the fan didn't turn on but after a while it did. The engine seemed to make a constant ticking noise as if the timing was out of sync camshaft? the engine was still at normal running temp. 3 hours later after letting it cool down. Its been parked up all day as I've been scared to drive it as i don't want to fuck up the camshaft or the cds... Any ideas? Thanks in advance
April 5, 2014
  Followup from the Pelican Staff: I would pressure test the cooling system. If the system does not hold pressure and there are no external leaks, you may have a faulty head gasket. - Nick at Pelican Parts  
mark Comments: I have a BMW530i 2004. yesterday my car starts to have a white smoke out of the exhaust just when you turn it on or you press on the gas if it is on parking. then the engine start to have a weird noise plus the car starts to shake as if it is going to turn off while I am stopping and hitting the brake. please if you can tell me what is wrong.
March 26, 2014
  Followup from the Pelican Staff: White smoke is likely coolant. I would pressure test the cooling system. If the system will not hold pressure and there are no external leaks the head gasket may be faulty. - Nick at Pelican Parts  
Danyboy32 Comments: Hi my service engine soon light was on. I recently replaced my smog pump on my 2002 bmw 325i which the light was on for in the first place and the mechanic told me not to go over 55mph. I did go over 55mph because it has to read the monitors and now the service engine so into light is on again...

  Followup from the Pelican Staff: COuld be a fuel pump, ignition misfire or restricted exhaust. Start by checking the vehicle for fault codes. - Nick at Pelican Parts  
Chuck Comments: My 2005 X3 ran well for first 15 miles of the commute today then the low oil light flashed while at a stop light. during acceleration the low oil light stayed on and within 100yds the car died and would not start. A road service tech added 2 qtrs of oil and it started but would not move. It was towed to a BMW dealer who stated that there was oil pressure build up leaking from the value cover. They cleaned the plugs with no luck. They suspect that it may be a camshaft sensor but fear that there may be damage to the shaft. Is that possible? It feels like the dealer is guessing at a very expensive rate. Any suggestions?
February 11, 2014
  Followup from the Pelican Staff: The camshaft can be damaged from low oil pressure, however I am unsure of the correlation between the sensor being faulty. Your vehicle can stall and not start if it runs out of oil or oil pressure, if your oil light came on and you continued to drive, I would assume engine damage has occurred. - Nick at Pelican Parts  
Hank Comments: Follow up on Stuck Error 65 Camshaft Sensor:

I used a different set of wires from Camshaft Sensor connector to the DME connector with no change in results. Still have +2.58 volts on Black wire. Error still in DME. INPA indicates Error Present and Error Static.
February 9, 2014
  Followup from the Pelican Staff: Have to looked at the digital signal from the sensor?

I would advise against using INPA, unless of course you are a factory engineer. - Nick at Pelican Parts
 
Two face Comments: I have an 04 bmw 325i with 92k miles on it. Recently done a tune up including spark plugs. Even before I done the tune up I would have a sputter between 55 to 70 mph with the rpms below 3k. Floor it and it smooths out. No light on. Other than this it runs fine. I just don't like the shutter when giving a little gas. Any idea?
February 3, 2014
  Followup from the Pelican Staff: I would check if there is a coil failing. It common for that to happen on your model. Check spark output using a spark tester at each coil - Nick at Pelican Parts  
Rob Comments: I have a 2005 e46 330xi which will crank but not start. I have the SES light on and code P1515 was stored. I can hear the fuel pump priming, and I can smell gass when cranking. New battery and spark plugs replaced in summer. Is this symptom of a cam position sensor issue, or throttle sensor, or other? I dont have a volt meter.. Any steps you recommend I try first, or should I proceed with replacing cam sensor? Thanks.
February 3, 2014
  Followup from the Pelican Staff: You will have to confirm what is missing, is it actually getting fuel? I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and pressure fuel, volume and quality. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.
If you have limited test equipment, lean on a friend for some help or seek professional guidance. - Nick at Pelican Parts
 
Hank Comments: Hello, the wires do not have to be cut then repaired to test. With nothing on the ends DME or Sensor it is just wiring harness. I have another wire set that I may try, because I can remeber if I check each wire to the shield. I may also use a external power supply to provide power to the sensor and see if there is a pulse signal with engine running. I will keep testing. I don't think every sensor I have purchased is bad out of the box. The last two being Siemens 1703122 parts.
February 2, 2014
  Followup from the Pelican Staff: The harness can be shorted, that is why this step is included. - Nick at Pelican Parts  
Hank Comments: The 2.55 vdc was measured at the DME connector pin and also at the harness wire from DME at sensor connector. I checked each wire with the DME and Sensor disconnected for open or shorted wires, they all are good. Resistance was also good.

I can clear the error 65 from DME, but it returns immediatly as a static or pending error. I looked at the reluctor on the canshaft and do not see anything wrong? It has a single VANOS but I did not mess with it just looked.
February 1, 2014
  Followup from the Pelican Staff: OK, but the wire could ne shorted. It has to be cut to determine if the wire is shorted or if the DME itself is not sending the correct voltage. 2.5 volts sounds too low. - Nick at Pelican Parts  
Hank Comments: Thank you for your assistance: with the sensor unplugged I get 2.55 VDC on supply black wire. Similar to the thread from Joe, I tried sensor from pelican and sensor from dealer yesterday. Can Vanos do something to interfere with Cam reluctor or pick-up wheel? or is DME electronics fried and cam angle and rpm does not change when engine rpm increased.
February 1, 2014
  Followup from the Pelican Staff: Is this 2.5 at the DME with the wire cut? It could be shorted. - Nick at Pelican Parts  
Hank Comments: Clarification on Followup? Nick, I am working on the 528i but both have the same engine. DME pin 64-black wire-pin 2 on sensor-supply voltage. DME pin 65-yellow wire-pin 1 on sensor-signal Dme pin43-ground. Should I disconnect the black wire at DME and supply a voltage to sensor? or discconnect the yellow signal wire and see if voltage returns on black wire?
February 1, 2014
  Followup from the Pelican Staff: I would start at the sensor to identify what may be at the DME. For example, there could be a 5 volt ref for the signal wire, and a 12 volt ref for the signal supply, then the ground. With the sensor unplugged, and the key ON, check what is present at connector. Then move to DME. HTH - Nick at Pelican Parts  
Hank Comments: 98 E36 328i and 98 E39 528i cam position sensor CPS code 65 found wires had brittle and missing insulation so obviously had shorted while engnine running. Cleared codes and replaced CPS several times and fault codes for CPS reappear. I swapped computersDMEand code still there. With unplugged CPS reference voltage is 2.55 DCV pin 64-black wire should it be 5, 10, or 12 volts? Wiring test good to ECU connector and pins. Could have shorted CPS blown the ECU circuits? Any suggestions? What can I check next?
February 1, 2014
  Followup from the Pelican Staff: E36 should be 5 or 12. I would go to the DME, cut the wire for reference voltage and see if it goes to a normal reading. If so, just run a new wire. - Nick at Pelican Parts  
ram Comments: I have a 1996 bmw 318i my transmission when it hits 3rd gear it stalls and stays on 3rd gear and transmission light comes on and it also stalls and dies when i get to a stop plz help
January 30, 2014
  Followup from the Pelican Staff: I would start by checking the vehicle for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing. You likely have a fault in the transmission or the transmission electronics. - Nick at Pelican Parts  
Pep357 Comments: Regarding camshaft sensor is there no resistance on connector
January 29, 2014
  Followup from the Pelican Staff: Which connector? Resistance is not the best test for camshaft sensors. - Nick at Pelican Parts  
kens330xi Comments: My 02 330xi died at 70mph on the freeway. It sputtered a couple times and that was it.

Replaced the Cranshaft sensor, but still no spark or fuel pressure. Is it likely one of the cam sensors? How do you test them? what else could it be besides the dme?
January 24, 2014
  Followup from the Pelican Staff: I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.

If you suspect the camshaft sensors, you can check the ground, reference voltage and signal from the sensor to the DME. The signal should be a 5 volt digital signal.- Nick at Pelican Parts
 
Pep357 Comments: I have 93 325i how can I test the camshaft position sensor please advise
January 23, 2014
  Followup from the Pelican Staff: There are three wires, one is the ground, one is reference voltage, the other wire is the signal. It will either be a 12 or 5 volt digital signal. Use a dvom or lab scope to test it. - Nick at Pelican Parts  
Rod Comments: I have a 2001 BMW 325i.  The other day the Check Engine light went on and now when I start it I see the EML message come up – next to the check engine light. I didn’t get it to the shop yet but yesterday as I drove, the engine felt like it was missing 1 cylinder from firing – giving a fairly rough running, almost putting feel.  I stopped the engine then restarted and it ran smoothly.  I do also notice some rough idling which is really undulation where the idle will vary 500-1200 RPM.  After reading some forums I saw some people changing the Cam Position Sensor.  Does this sound like the correct path?  Any input would be super helpful! Thanks

  Followup from the Pelican Staff: I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing. I wouldn't change any parts until you have an idea of what is going. EML could e throttle hosing issues, sensor issues or a few other things. - Nick at Pelican Parts

December 27, 2013
  Followup from the Pelican Staff: If the bolt in the VANOS actuator broke, the camshaft and valve may be damaged. I would perform a cylinder leak test to see if you can repair it or will need to replace the head or engine. - Nick at Pelican Parts

BabsBMW Comments: Grateful I found this.... I know nothing about cars. 59 plate 120i Convertible... Started jolting, occasionally light would come on- sometimes just flash, sometimes longer. Apparent mis-fire, replaced 2 coils, codes cleared & ran well for a while- now its back. Jolts badly- have now had 3 coils replaced in 18 months. Is it best to replace all coils at the same time? Could this be anything else? Someone mentioned it could be something back in the fuel causing misfire?
December 23, 2013
  Followup from the Pelican Staff: I prefer to replace all coils at the same time. However, that can be costly. You could also have an injector problem or base engine. I would attempt to identify the component causing the misfire before buying any more parts. - Nick at Pelican Parts  
Ross Comments: Car acting very strange. 2000 e39 540. Only when starting the car, very hard vibration when reving, when i shift in gear and start to go, i found that the vibration goes away once i hit a certain rpm 'threshold'. This happens everytime i turn the car off and start it. My mech said its a misfire issue which i dont doubt, where do i start? I recently replaced the cps on the passenger side because it was frayed badly and thought it could be causing my power loss. The vibration wasnt there before that. Pulls very hard once im past that threshold3-4k and is very sluggish before
December 17, 2013
  Followup from the Pelican Staff: This could very well being an engine misfire. Start by checking the DME for fault codes, as the misfiring cylinder may have been identified with a fault code. Once you locate the misfiring cylinder, check for good spark, fuel and compression on that cylinder. - Nick at Pelican Parts  
juan Comments: Yes i put the fault code n got P0341 P0012 n P0015 for the BMW 530i 2006 any help
December 16, 2013
  Followup from the Pelican Staff: The P0012 and P0015 codes lead me to believe there may be a fault with eh VANOS actuators. - Nick at Pelican Parts  
chocolate Comments: I have 2001 BMW 325i The car cranks over but will not start.
I put new spark plugs, changed oil, and new air filter. I think it's my fuel pump, I don't hear no buzzing sound when I crank the car over.
the fuel pump relay is good also, another person it might be my camshaft sensor
December 14, 2013
  Followup from the Pelican Staff: I can't help without knowing what is missing from the system when you are trying to start it. When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and pressure fuel, volume and quality. Once you figure out what is missing, it will be easier to diagnose.
- Nick at Pelican Parts
 
rmp Comments: Thanks for the reply. The code number is 11, i scanned with peake scanner
December 11, 2013
  Followup from the Pelican Staff: You could have a dirty VANOS unit. Check that the camshaft sensor signal is getting to the DME, if it is. Check function of the VANOS unit and camshaft timing. - Nick at Pelican Parts  
Liala Comments: I have a 2003 530i bmw I bought used with about 140k miles on it now. 1 month ago I went in for a routine oil change after I got my car back the problem started! It started to idle very hard when ever I come to a stop or the rpm drop below 1000. In fact it idled so hard and stalled twice when I was leaving my mechanic. He looked at it and said I needed a new vaccum hose which we got and put in and the problem is still the same maybe WORSE. I took it to a dealership and after spending 300$ to diagnose they said they need another 1000$ to look in side the engine at which point I ran out of money : plz Help!
December 11, 2013
  Followup from the Pelican Staff: This could be anything from a vacuum leak to an engine misfire. Are there any fault codes stored? - Nick at Pelican Parts  
juan Comments: I have BMW 530i 2006 it crank but wont star n no spark
December 11, 2013
  Followup from the Pelican Staff: is spark the only thing you are missing? Check to see if injector pulse is also. If so, check the DME for fault codes. There may an issue with the theft system or the crank sensor. - Nick at Pelican Parts  
RMP Comments: hi, i have bmw e36 m52, i scanned the car, it has camshaft position sensor error, i replaced the sensor with new one oem and then clear the code, but same error and still rough idle, loss power etc

December 9, 2013
  Followup from the Pelican Staff: The wiring to the DME could be faulty. What is the fault code number? - Nick at Pelican Parts  
Mike Q Comments: I have a 96 318i that has a camshaft position sensor on and occasionally turns off is there any way too clean the sensor with out replacing it.
December 5, 2013
  Followup from the Pelican Staff: The failure is likely to be electrical and not (directly) related to dirt on the sensor. If you can remove the sensor easily and clean it, go for it but don't expect any miracles. - Nick at Pelican Parts  
Mad max Comments: Hey, you seem to know your stuff:-
2003 BMW 525 m sport auto,
Every so often out the blue just as the engine starts warming up seems to always be in the first 3 odd miles or 5 mins it missfires and acts like it's run out of fuel, leave it for the rest of the day till it's gone stone cold again and it will restart some times misses for a few seconds the back to normal and then is fine for weeks or months! Any ideas?
November 28, 2013
  Followup from the Pelican Staff: I would start by checking the DME for fault codes. If the system is not working properly, a fault code will be set. This will be your best bet when diagnosing.


You could have a vacuum leak or a faulty crankcase breather valve. I would check both, inspect the engine for a cracked intake boot, vacuum line or leaking gasket. You can also check the crankcase vacuum, this will help you diagnose the crankcase breather valve.


Next I would perform a fuel delivery system test. Check fuel pressure, volume and quality. - Nick at Pelican Parts

November 26, 2013
  Followup from the Pelican Staff: You didn't mention the year of your vehicle.

You could have a vacuum leak, depending on what year 325i, it could be a faulty crankcase valve. - Nick at Pelican Parts

Greg Comments: I purchased a 2002 BMW 330xi about a month ago. When I'm driving at a steady speed on fairly level terrain while holding my foot steady/still on the accelerator, the rpm drops about 200 rpm and then back up 200 rpm. It will keep fluctuating up and down like this every few seconds as long as I don't move my foot on the accelerator and the road remains fairly level. This seems to be the most noticeable around 40 mph, but does it at other low speeds as well.

Also, between 60 & 70 mph there is a slight vibration and hum sound. Tires were balanced and four-wheel alignment done which did not make any difference.

I had it at a BMW service garage for 2 days and they could not determine what the cause is for these issues.

Thank you for your help.
November 25, 2013
  Followup from the Pelican Staff: is this a stick or an auto? either way it sounds like the drivetrain is slipping. - Nick at Pelican Parts  
Juan Comments: I have a E39 528i which has a camshaft position sensor error, it idles poorly and accelerates poorly as well as fuel consumption, I changed the sensor with one "generic" but with the same part number and new from ebay and I have the same problem, should I blame this sensor?
October 28, 2013
  Followup from the Pelican Staff: I would check the power and ground supply to the sensor, and also the signal wire, if they are all ok, i would replace the sensor. Give our parts specialists a call at 1-888-280-7799. They can help you find the right part.

Any help would be much appreciated.
October 16, 2013
  Followup from the Pelican Staff: This may be a faulty idle control valve. That is assuming no vacuum leaks, as you stated you checked. Before replacing it, check crankcase vacuum to confirm the crankcase breather valve is working normally. - Nick at Pelican Parts

I will like check it manually before to proceed with replacement.
Thank you very much.
October 11, 2013
  Followup from the Pelican Staff: That part number comes up as a crankshaft sensor, not a camsensor. To check the crank sensor measure the resistance on pin 1 and pin 2, it should be 540 + or - 54 ohms, if not the sensor is faulty.

Mark Comments: Hi, have a 95 OBDI M3. I have been getting a check engine light that periodically comes on and off. It is for Throttle Position Sensor circuit fault code and have replaced my Throttle position sensor and still getting the code. Is there any adjustment that the sensor requires or perhaps is there a common fault that triggers the "sensor circuit" code?
August 26, 2013
  Followup from the Pelican Staff: if it is a circuit code, I would check that the signal is getting to the DME. Check for 5 volts, ground and a good sweeping sigbal from the sensor all the way to the DME. - Nick at Pelican Parts  
Charl320i Comments: Someone help: I have a 1994 320i E36 M50. On idling it revs at just above 500 regardless of whether it's cold or warm. The fuel and temp needles remain put in their resting positions. When I start moving while still cold, rev drops to 0; fuel guage and temp needle also drop to 0 until warm. After that it depends on speed - the three needles seem to be in normal positions below 1000 and above 3000 but but fall back to 0 in between. What could be the issue?

ZenJelly Comments: 2001 325i, 190K miles. I was getting a terrible idle and a code P0014. I changed my VANOS seals hoping to correct the problem. While the seals were bad and my idle did improve a lot it's still a bit shaky. From what I'm reading it seems like the Exhaust CPS is bad, does that seem right?
July 29, 2013
  Followup from the Pelican Staff: It could be the vanos solenoid itself that is failing, or the cam adjuster itself may be sticking. Give our parts specialists a call at 1-888-280-7799 and they can help figure out which part or repair kit you need.
- Nick at Pelican Parts
 
howzabout Comments: If you would care to comment on my situation- I'm currently waiting for parts and tooling to replace my head gasket, in a 98 m3 127k miles. It's a difficult process, and I'm needing to do a lot of research before getting completely into it. I'm having a conversation with my kid, a car nut, and he is urging me to replace almost every part I run into so I will not have future problems with them- including the Vanos unit, cam and flywheel sensors, timing chain tensioners, radiator, hoses, etc. It's getting very expensive! What's your thinking on this proactive approach? I tend to think I'll fix things when they go wrong, as unrelated parts can break just as easily. But I also see his point.
July 26, 2013
  Followup from the Pelican Staff: - Ken at Pelican Parts I understand your dilemma. When I do a job like that, I consider how much the parts cost, how much damage they can do if they fail, and how hard they are to replace afterward vs now. Definitely replace parts like hoses, which should be changed every 5 years or so anyway. I would also change the timing chain guides and tensioner. Remember that the car is 15 years old. If the sensors and Vanos unit were functioning fine, I'd probably take my chances with them. But at the end of the day, you have to decide: Am I feeling lucky?

Susan Comments: Two questions. First I have a 1990 bmw 325i e30 and can't seem to locate the camshaft positioning sensor. Second, my car seems to no longer get fuel once the engine is warm, I have replaced the fuel filter and fuel pump relay, it idles much better now however still cuts off putters of as if lacking gas. Any ideas? I believe my actual fuel pump is still good.

July 13, 2013
  Followup from the Pelican Staff: Sounds like you could have an engine misfire. If the problem goes away once the engine is warm, you could have a vacuum leak or ful delivery problem. Checking the DME for fault codes would be a good place to start, as a fault code will point you to the problem cylinder(s). - Nick at Pelican Parts  
Merv Comments: i took my vehicle for a car wash after i washed it, the car was death. i then took it to a auto electrician only to find out that the ECU was filled with water. i replaced the box with a different DME box and the car started but it refuses to rev and it back fires to the intake menufault. i then opened the replacement box and the old one and i swaped the removable chips as i heared everything has been recorded on that particular chip that comes with the vehicle from the market. my only question is, can these chips also fuse when it gets water or is it only the board that fuses?
July 9, 2013
  Followup from the Pelican Staff: Any electrical part that gets wet during use can and will fail. The DME and the chip alike. You may have more damaged items from the water intrusion. - Nick at Pelican Parts

merv Comments: I did check on the misfiring and it use to do the same before I replaced the computer box but it use to drive just fine. The new box I put in is a DME make, I don't know could it be the bar code number that defers because the one that was in is:0261203279 and the replacement is:0261203289. Could it have something to with the mapping of the box as the car sound to be out of timing hence it idle.
July 7, 2013
  Followup from the Pelican Staff: If the part numbers do not match, the replacement part may not work. YOur best bet is to check with BMW to be sure. It is possible having the DME coded may be the fix. - Nick at Pelican Parts

July 5, 2013
  Followup from the Pelican Staff: The fault code numbers would point you in the right direction. If you have cam crank correlation codes, which it sounds like you might. This could be a VANOS issue. If you had a professioanl diagnose the system you have the info as to what is wrong. If you think the repair is overpriced, you can call other local shops and ask for an estimate. This might b e your best bet. - Nick at Pelican Parts

After it cools off, it will start again and run for a few minutes and then dies again. i can't figure what is causing the problem. car will stop after it gets hot if i grond the positive terminal it reset the computer i had a remote i lost it could it be a esw 11 problem security related problem ,i also notice when car warm up it start to miss fire like coils are not firing intake back fire like its not getting a camshaft signal for the computer to determin which cylinder to fire next all did is whash the engine it start acting up after that i checked the dme it didnt get wet i opened it to make sure no water gets in there ,also airbag light stay on i took apart the seat belt buckle and use a tape to keep the contact close . Help please.

  Followup from the Pelican Staff: A sensor could be failing when hot, which is quite common. Then once cool again it will begin to work.

When your engine doesn’t start you’ll want to check the basics. Check spark, fuel injector pulse and fuel pressure, volume and quality. Once you figure out what is missing, it will be easier to diagnose. - Nick at Pelican Parts
 
DRO Comments: How you doing i have a 325i bmw 2001 sedan 6cylinder .when i turn on the car i can hear and feel a jerking sensation when i put it to drive it jerks when its in a little speed also when important coming to a stop i feel the car jerking at speeds between 20mph to 0mph i can also hear the muffler giving like a jerking sound like if it wants to die and when i step on the gas to get the rpm up the car dies any idea what it could be i would really be thankfull for any advise.Also i think i have a bad wheel bearing when i pick up speed to 20mph and up i hear a roaring sound it gets louder the more speed i pick up and makes the car vibrate alot could it be the wheel bearings or some thing else??

  Followup from the Pelican Staff: You could have a faulty crankshaft sensor. Engine heat could be making the problem arise, then ocne it cools off the sensor returns to normal. - Nick at Pelican Parts  
Don Comments: I replaced the Camshaft sensor on my 96 318i and when I started the car it ran rough. I know the computer has to be reset will that happen automatically or do I have to go to a dealer to have it reset?
June 24, 2013
  Followup from the Pelican Staff: The fault code will reset after 3 complete drive cycles, or by using a scan tool. If you do not have access to a scan tool, you can wait until 3 consecutive drive cycles without a fault occur. - Nick at Pelican Parts  
mike Comments: I have been having problems with my 95 318TI. While running, after avout 5 minutes, it will die. After it cools off, it will start again a run for a few minutes and then dies again. My mechanic can't figure what is causing the problem. Already changed the cam sensor and also tried the coil to make sure it was getting a good spark. Spark is fine, but will car will stop after it gets hot. Help please.
June 23, 2013
  Followup from the Pelican Staff: If you engine doesn't start, you'll want to check spark, injector pulse and fuel pressure when the problem is present. This will help you pinpoint the problem much easier. If you have good fuel pressure and are missing spark and injector pulse, suspect the crank sensor. CHeck the DME for fault codes. - Nick at Pelican Parts  
Karen Comments: The repair was made, but has not been reset. I fixed it and the check engine light is no longer up. Thanks anyway. The mechanics around here couldn't fix it either, so I found a way to fix it myself. Amazing for a woman that never did mechanical work before to fix something a mechanic couldn't. When the repair is fixed, the computer has to be reset, that was all. An easy repair installing the new camshaft position sensor, in light of the fact that BMW or a mechanic would have charged me a fortune.
June 17, 2013
  Followup from the Pelican Staff: You are correct. When a fault code is set, it will not clear immediately unless you clear it using a BMW scan tool. It will however automatically clear after two drive cycles witht he fault no longer present.

E46Paul Comments: Re: my previous post, that link is for a 6 cylinder engine. The Haynes Manual only shows one on the M43 engine. I could only find one on realoem too? Surely my reference voltage is wrong?
June 17, 2013
  Followup from the Pelican Staff: I apologize, I missed your engine code reference the first time around.

Reference voltage could be 12, 10 or 5 volts. I would check the signal to the DME as well as the other circuits back to the DME. - Nick at Pelican Parts
 
E46Paul Comments: I have code P0340 on an E46 M43 engine. There is only one CPS I believe on this which I've changed but its still bringing the code back. The middle wire is showing 10 Volts not 5. I assume the problem is in the circuit somewhere?
June 16, 2013
  Followup from the Pelican Staff: There are two camshaft position sensors. This tech article should help: http://www.pelicanparts.com/BMW/techarticles/BMW-3-Series-E46/19-FUEL-Camshaft_Sensor_Replacement/19-FUEL-Camshaft_Sensor_Replacement.htm - Nick at Pelican Parts  
Karen Comments: It is the correct sensor, because, I went to the Auto parts store to verify it. The fault code shows up as the intake sensor and as I mentioned before, the check engine light went out after I first started to drive it, and I am not having any problems with it as I had been before installing it.
June 14, 2013

Karen Comments: I was having a stalling upon acceleration problem, after running the car, parking it and restarting it. Obtained a fault code reading that indicated that the camshaft position sensor intake side was bad, so I replaced it myself, after watching a video and no mechanic in town knew how to fix it. Well, I was so proud of myself, especially when it started up just fine. The check engine light was still lit up, and received the same fault code. After driving it a few miles, the check engine light went out, however, it has come back on again after a few days, but am still not having any stalling issues. However, the exact same fault codes show up, so now what?

June 13, 2013
  Followup from the Pelican Staff: be sure you replaced the correct sensor, intake or exhaust. The fault code will note the location. If you did, check the wiring back to the DME and confirm the signal is making it there and is correct.- Nick at Pelican Parts  
chowda Comments: 2001 BMW 325i Got the code for the CPS after re-timing the engine. Did a head job last year for a burnt valve and kept getting codes for the vanos after everything was put back together. The timing was off a hare so this time we tore down the timing put everything back exactly to spec. And the vanos codes went away and a CPS code popped up. Replaced the CPS with a BMW sensor problem still there. Check wiring and plate position all fine. Cleaned the hole the sensor goes in measured distance all perfect and sensor sending a signal as well. What are we missing?
June 12, 2013
  Followup from the Pelican Staff: I would check the signal to the DME. You may have a broken or shorted wire. - Nick at Pelican Parts  
Brad Comments: 2001 530i Hard start and shifts
Hi I have a 530i that I have been working on for a while. I had a CEL and replaced a number of parts both cam sensors, thermostat housing, and vacuum lines, CVV, etc. based on codes, symptoms and findings that resulted in all clear and good performance for a few months. Recently we have had a hard crank issue, a CEL codes: P0727, P0335 and a transmission light as well as hard shifts auto, especially when slowing. I replaced the crank sensor 3x, the last with a dealer part, and the problem persists. I am thinking maybe a fault in a wire?, but I don't know. Any suggestions would be greatly appreciated as this is our only car. Thank you.
June 8, 2013
  Followup from the Pelican Staff: Both fault codes point toa problem with the crankshaft position sensor circuit. I would check the wiring harness integrity from the sensor to the DME. - Nick at Pelican Parts  
Minnierolltide Comments: I got a code for a camshaft sensor error, but I've replaced it several times and the code comes back post vehicle stalling. Here is what is weird. I disconnected the wires to the camshaft sensor and the vehicle still runs and starts no problem. How could this be?
June 1, 2013
  Followup from the Pelican Staff: If the sensor has been replaced and the code is still present, I would check the wiring and the sensor signal at the DME.

The engine may start without a camshaft sensor, it will sync off the crankshaft position sensor. - Nick at Pelican Parts
 
Tom Comments: 95 318ti/m42, running on 3 cylinders following a crank position sensor failure/replacement. Previously had a coil failure - shorted and fried DME #1 coil. Replaced DME ran for several months. Now no spark on #1 with new coil. Have power to coil and continuity on all coil wires. Tried multiple DMEs with same dinan chip. What could cause no spark on #1 - partially fried chip? Cam position sensor? Other?

Claire Comments: Hi I have been having big problems with my 1series BMW. At starting the car chugs and shacks and as the car starts to move it gets bit better. When it's idol at traffic lights ect it shacks and chuggs again. Engine light comes in about 1 minute or so after starting. Computer reads cam shaft . We have replaced it and the sensors. And now I wonder if they have put BMW parts in Or universal parts. Wud this make a difference or do u think there is a bigger problem?? Any help much appreciated

  Followup from the Pelican Staff: What is the P-number of the fault code? You could have an issue with cam timing, which replacing the sensor would not remedy. - Nick at Pelican Parts  
jo Comments: How do i test sensor
July 3, 2012
  Followup from the Pelican Staff: Are you referring to a 2 or 3 wire camshaft sensor? 2 wire, connect a DVOM across the terminals and crank engine, you should have at least 0.5 volt AC. 3 wire, Check for correct voltage, 5 volt DCreference, sensor ground 0.1 volts DC, then signal wire should pulse from 0-5 volts DC when turning engine over by hand. - Nick at Pelican Parts  
Spuddy98 Comments: On a 325xi you only need remove the air filter housing. The connector plug is right behind the alternator. No big deal in removing tricky parts. Maybe other models are different. Is there any diagnosis help? I have replaced the intake sensor and I still get the code occasionally. Could it be an exhaust code? Is there a way to confirm the wheel is in good shape?
May 7, 2012
  Followup from the Pelican Staff: There are two ways to test the sensor. You can check the sensor signal using a lab scope connected tot he sensor ground, expect to see 0 to 5 volts square wave. Or using a DVOM connected to the sensor signal, with the key ON, turn engine over slowly by hand, the reading will switch from 0 to 5 volts at the sensor passes the reluctor wheel. - Nick at Pelican Parts  
Chris B Comments: I have a 96 BMW 328ic convertible. It has the 6 cylinder engine and needs the crankshaft position sensor replaced. I used to be a mechanic years ago but mainly on Oldsmobiles and Nissans. I have the new sensor but I cannot locate the old one on the engine! It's not up front, the manual says it's supposed to be there, but it's not. The hole is there but no crankshaft position sensor. It's not under the intake. I pulled the intake and looked where some crank sensors were supposed to be located and guess what, it's not there either. What a mess now to put back together. I saw a video on youtube, one guy said it's in the back under the car near the transmission, well maybe it was there on his but not on mine.....so where is the "dang" thing? I kinda feel like writing BMW a letter and telling them to get their act together about placing their crank position sensors in ONE spot only. Anyone got any ideas for a location on this thing? Thanks, Chris B.

  Followup from the Pelican Staff: The crankshaft sensor should be mounted tot he right front of engine. This is where BMW placed them on E36 models. On later models, the crankshaft position sensor is of the left side of engine, at transmission bell housing, usually a little below the starter. - Nick at Pelican Parts

March 13, 2012
  Followup from the Pelican Staff: If you replaced the idle control valve and still have an issue, you may have a problemw itht he DME. This TSB relates to your problem indicatng a fault with the DME. I would test the system using a BMW scan tool, if the tests are above your ability, take it to BMW work shop. DMEs are expensive and you don't want to buy one if you don't need it.

Tony Comments: Hi, I have a 02' 745i and it's throwing two codes, p0294 and p0012 can you please tell me what it is and how to fix it? Thanks alot
March 3, 2012
  Followup from the Pelican Staff: P0294 points to a problem with a fuel injector cicrcuit. P0012 points to a camshaft timing fault. The codes vary a bit vehicle to vehicle. You'll need to scan using a BMW scan tool and retrieve the BMW specific fault codes. - Nick at Pelican Parts  
Josh Comments: I have the exact same problem as phil from Nov. 16 2011 posting, would love to know how it got fixed?
February 27, 2012
  Followup from the Pelican Staff: If the engine is misfiring, I would address that and not get hung up on the camshaft sensor scenario. Run the engine and check for fault codes. You should have a code to identify the misfiring cylinder.


Connect both sensors, verify misfire and locate source of misfire. Treat it as any engine misfire diagnosis, do not get distracted by the camshaft sensor scenario you described. Check for good ignition voltage, good fuel injector operation and engine compression. One of thos ethree will be faulty creating the misfire. - Nick at Pelican Parts

Phil Comments: Im Having an odd fault with my cam sensors on an E46 318i, I had a broken exhaust cam sensor when i bought the car so i replaced it with a new one. Now when i start the car i get a misfire on cylinder 4. I have verified the sensor works as i have swapped the inlet/exhaust sensor and get readings from both individually with car diagnostics.

If i disconnect the exhaust cam sensor the car will not misfire and runs normally. if i connect up the sensor and start the car i get a misfire. But this is where it gets odd if i start the car with the exhaust sensor disconnected and connect it after the car runs properly with no misfires and i can read both sensors however back to misfire after engine restart. Its like the system does a check on start up that fails with both connected.

Anyone got any ideas?

Thanks

I have checked from the pump connector all the way back to the DME thru the fuse, relays and wiring harness and see no indication of faulty relays, or wiring. DME giving no fault codes 1444. Pulled DME and no signs of corrosion, loose contacts. If the either the CAM/Crank sensors are bad should I get a fault code? OR if they are indeed good getting no codes but not reading properly ie metal plate inside broke/corroded would I still get a fault code? Thanks.

MRH Comments: I Wayne. I'm the one from european M3 3.0. I wrote some posts below. Thanks to you, i resolved the problem of my car - when warm, engine just start on second try and have oil in intake - i changed the oil separator. But now i have another problem. I cleaned again my ICV and now it isn't working. The car can´t idle, just starts with part trottle, and when i'm on the road i can't let the engine rpm down to idle, otherwise the engine cut off! If i let the revs down slowly the engine stand runing, but very rought, at 500 rpm! My questions: could the icv may have damage 100%? Could be the wires that plug in it, incorrectly fitted? Could some trottle cleaner reached the plug? Could be another problem?
Finally, If i decide to buy a new ICV do you see any problem in one from another brand than OEM bosch its to expensive? Or its better an used bosch? I'm getting mad with this car... Thank you again. Best regards. Marco

MRH Comments: Hi Wayne. I post two coments before, about my car. It is a european E36 M3 S50B30 - 286hp. The photo was taken under the car, on the left side of the engine. What we see is a junction in the intake duct, but invisible to those who look from the engine compartment. I investigated, including your articles, and the oil in intake problaby come from cranckcase ventilation system - oil separator. Thank you again. Kind regards from Europe.
February 13, 2011
  Followup from the Pelican Staff: Quite possible. The air-oil separator is an emissions device that pulls gases from the crankcase and then sends them back to the intake. I'm not sure about the Euro cars specifically though. - Wayne at Pelican Parts  
MRH Comments: Hi Wayne. You were right! One of this days i was working underneath the car when i found an oil leak. When i look carefully i found a HUGE vacuum leak on the junction of the air duct with air collector, as you can see in the picture. My answer now is if it's normal that oil on intake. Its true that i drive very hard before! Finally, the car still have a difficult start when engine's hot starts on 2/3th try. After all i checked before i think the problem is from main ECU. Someone told me could be Vanos ECU! The car runs fine, even on low and mid revs. What do you think? Thanks a lot again and congratulations for your experience and knowledge.
February 12, 2011
  Followup from the Pelican Staff: It's not normal to have oil leaks. I can't tell what I'm looking at from your photo unfortunately. If you had one vacuum leak, you might have more. You might want to smoke out the car with a smoke machine - see my article on doing this here: http://www.pelicanparts.com/techarticles/Boxster_Tech/21-FUEL-Vacuum_Leaks/21-FUEL-Vacuum_Leaks.htm

There is no such thing as a VANOS ecu, as far as I know (although I'm not exactly sure which car you have). ECU failures are not rare, but vacuum leaks and other component failures are much more common overall. - Wayne at Pelican Parts
 
Soldiurblu Comments: Hi,
Great website and very informative forum, thanks.
Now to my problem and personal vendetor. I have recently acquired a european 1994 E36 320i MSport Coupe with a single Vanos. The vanos unit has been replaced very recently however the engine is a non runner. BMW have carried out a diagnostic and no faults were found, the ECU has been reprogrammed as that was questionable and still nothing. We are only receiving a spark from nos 2 and 5 cylinder, all sensors have been replaced except for the CPS and all Ignition Coils have been checked and are functional. I appreciate that this is quite a long and drawn out saga but I am now lost for ideas, can anyone help?
February 1, 2011
  Followup from the Pelican Staff: No faults and no spark is very odd. I would think that maybe there's a problem with the DME, and I would see if you could swap it out with another one. If the car is not firing properly, then the DME *will* know that and will indeed report that as an error. If it doesn't, then there's probably something internally broken within the DME. - Wayne at Pelican Parts

February 1, 2011
  Followup from the Pelican Staff: Okay, so we know that the cam sensor itself is not the problem. There can be a few other things to check. The cam sensor gets its reading from a metal plate inside the top of the cylinder head that spins past the sensor. You can check this to make sure that it's not coated with some sludge, or broken, etc. See the cylinder head gasket replacement article for pictures of this. You should also check the wiring from the sensor to the DME. The sensor may be replaced, but the wires that the sensor plugs into may be corroded or not making full contact. Trace them from the harness in the engine compartment back to the pins on the DME. If all of this checks out, then there might be an internal problem with the DME. Also check the connector on the DME to make sure the contacts are bright and shiny. - Wayne at Pelican Parts

and neither one could solve the problem.

  Followup from the Pelican Staff: Sounds like a vacuum leak to me that only happens when it's cold. I wrote an article on checking for leaks here, you might find it useful: http://www.pelicanparts.com/techarticles/Boxster_Tech/21-FUEL-Vacuum_Leaks/21-FUEL-Vacuum_Leaks.htm - Wayne at Pelican Parts  
josh12345 Comments: hi i bought a 96 bmw 328is with a check engine light on and ran the scanner snap on solus. code p0340 or 65 came up so i tested the wireing for the camshaft position sensor it was fine so i replaced the sensor and cleared the codes and code p0340 came right back up other than the pcm is there anything else that im overlooking

  Followup from the Pelican Staff: Those generic code readers can sometimes give odd or erroneous codes that don't match the proper ones for BMW. I would check it with another scanner. If the problem persists and the code is correct, then the problem most likely lies with the wire harness to the sensor - check it from the sensor plug back to the DME. - Wayne at Pelican Parts  
MRH Comments: Hi Wayne! Thank you very much for your atention. There is something more to tell. The bmw workshop told me, that maybe is the DME. Another people says its certainly something going wrong on intake, maybe a tight barely manifold...or, the bmw workshop poorly cleaned the ICV!!! It's curious that the car when is working on idlle misfires, and it increases as the engine heats up. Would you like to give a last opinion about it? Thank you very much again. PS: The car runs very well...

  Followup from the Pelican Staff: I would triple-check for vacuum leaks. I have a really good article on hunting for them here: http://www.pelicanparts.com/techarticles/Boxster_Tech/21-FUEL-Vacuum_Leaks/21-FUEL-Vacuum_Leaks.htm - Wayne at Pelican Parts  
purnell Comments: I have a 2003 525i BMW how many camshaft sensor are there and where are they located
October 31, 2010
  Followup from the Pelican Staff: On that car, there should be one camshaft position sensor, and it should be located in the same spot as is indicated in the article. - Wayne at Pelican Parts  
rishi b Comments: Hello,
Very good info guys... I have 1 quick question, How does one tell the direction of the fan? is it you facing the ingine or the other way around? I want to change the fan clutch...

  Followup from the Pelican Staff: The nut is a reverse thread as your standing in front of the engine. So, you turn it clockwise to loosen (the opposite of normal). - Wayne at Pelican Parts  
MRH Comments: Hi! Congratulations for those who create this site! I have a bmw e36 m3 coupe, european version. The car don't start, at 1st try when engine is hot! I change almost everything, crankshaf, camshaft and temperature sensor, clean IVC. The gas pressure, cylinder compression and coils were cheked. The injectors was cleaned... The car is on a bmw workshop and became a case study. They are unable to resolve it... Can somebody help me? Best regards.

  Followup from the Pelican Staff: Hmm, here are some thoughts. Check the fuel pressure for vapor lock in the lines. Also check the wire harnesses - as they heat up sometimes they can separate and show problems that would not normally show up when cold. If the car won't start, check fuel pressure and spark (diagnosis the old fashioned way), and see what you're missing. It may be that the heat may be affecting the DME too. - Wayne at Pelican Parts  
ryan Comments: I have a 1999 e36 bmw. my cars check engine light came on i checked the code and it was the camshaft position sensor so i put a new one on. now i have the power i lost back but my check engine light wont go off i tryed clearing it with the cheap autozone scanner and it wont clear it. does anyone no why it would still be on or how to clear it.
October 21, 2010
  Followup from the Pelican Staff: It's probably the scanner that is not able to clear it. The Peake Research tool clears the codes quite well. - Wayne at Pelican Parts  
Pavlo Comments: Hi, Thanks for all the brilliant articles, I have A 98 E39 523I Auto. It developed a huge power loss, and eventually died on me going up hill. As it got worse it developed a tapping noise, and started blowing white smoke from the exhaust. It now will not start.
Any Idea?
Many Thanks.

  Followup from the Pelican Staff: Check to see if the coolant engine oil are mixing. You could have a faulty head gasket. - Nick at Pelican Parts  
Stephen Comments: I just replaced my clutch flyweel, and all my tranmission bushings and washers using your diy. I put the car back together, and my asc light is on, and I have a code for the crankshaft postition sensor. COuld this be becuse I was turning the dirveshaft to get to the bolts? DId I damage the engine any or will the sensor fix the issue? THanks. I have not tried to bleed the system, and I thnk that may be the problem with the asc.
October 12, 2010
  Followup from the Pelican Staff: You may have damaged the electrical connector or sensor. Inspect them both. Turning the driveshaft by hand would not damage anything. - Nick at Pelican Parts  
Todd Comments: How can you tell/check if the camshaft sensor is faulty when the code has been eerased and won't come bask on and the vehicle runs erratic. Can you test it outside and off the engine. Can it be bench tested? I have a X5 with two of these sensors.
September 27, 2010
  Followup from the Pelican Staff: If the sensors are bad, typically the car won't run. If they are giving bad signals, then you will see a code. If the engine backfires or misses, then you might see a camshaft sensor code when it's really a false code. If you have re-installed the sensors and the engine is not tripping codes, then I doubt that they are the problem. - Wayne at Pelican Parts  
preatorians Comments: i have a bmw e36 318i single overhead cam its not starting not sure on the rocker arms what tensions should they be and should they be loose or should they be small movement or no movement thanks
September 12, 2010
  Followup from the Pelican Staff: I would pull the error codes from the computer before doing anything else - it will probably tell you what the issue is. - Wayne at Pelican Parts  
BigMyke Comments: I went to get my 2001 325i inspected and the Cps code for the exhaust popped up. I got it replaced drove it about 150miles and the engine light came back on and had the same code pop back up. Could something else be causing this code?
August 23, 2010
  Followup from the Pelican Staff: It could be related to the VANOS unit, or it could even be related to the type / weight of oil that you're using (if the VANOS doesn't like it). Change up the oil weight with something a bit different, clear the code, and see what happens? (wild guess) - Wayne at Pelican Parts  
Dave Comments: I have a 325i BMW-2001 and trying to remove the vanos solenoid to do a camshaft sensor replacement. My problem is that my canos solenoid is extremely tight so I cant remove it.Also used loosining oil and nothing. Dont want to brake it.. found different info at different forums online but nothing im doing it clockwise from the front of the car
August 21, 2010
  Followup from the Pelican Staff: See this tech article: http://www.pelicanparts.com/BMW/techarticles/BMW-3-Series-E46/19-FUEL-Camshaft_Sensor_Replacement/19-FUEL-Camshaft_Sensor_Replacement.htm It will help you get the repair completed. - Nick at Pelican Parts  
doublem94 Comments: hi. thanks for the article. I have a weird problem. My 96 328i stick wont accel past 5000 rpms, acting like it has a governor. The codes I pulled out are for the MAF, cam sensor, and speed sensor. Would the cam or maf sensor make my car acts like it has a rev limiter at 5000 rpms. the car idles fine. Just want to know if I should start replacing these immediately or if I have bigger problems. thanks
August 20, 2010
  Followup from the Pelican Staff: I would clear the codes, and then see what code comes back first - that's probably what I would replace first. The other codes may be related to the first one that pops. - Wayne at Pelican Parts  
chines Comments: Hello,
I have a 2000 323ci service engine light is on. Hooked it up to a computer and diagnosis codes were for a camshaft position sensor and an oxygen sensor. My car just recently became very underpowered. Is this due to the camshaft position sensor, or the oxygen sensor, or both. Also, how do I know which H2o sensor is bad? I thin I have 4 of them
July 16, 2010
  Followup from the Pelican Staff: If your cam sensor is off, it may be causing the car to run rich or lean, which can lead to O2 sensor errors. Replace the cam sensor first. The O2 sensor code should say which one it is 1 thru 4. - Wayne at Pelican Parts  
machintek Comments: 97 M3 with 140K miles was giving a cam position sensor CEL. Turned out the outside cover from the plug to the sensor was soft and flexible but peeling that back the insulation on the wires themselves was cracked, brittle and flaking off causing a short. I peeled back about 6 inches and it was still brittle and cracked but at least not falling off. I put 1/16 inch heat shrink tubing on the wires as best I could, put 3/32 heat shrink over that and the solder joints back to the plug and put 1/4 inch heat shrink over the whole thing. So far no codes and functioning flawlessly. But will need to get another sensor soon. Brings up the point of what other wires are in the same state.

TwoDogs Comments: While driving my 88 325i, I suddenly had a loss of power and the engine ran very erratically. With the help of a mechanic friend, discovered that the 2, 4, 6, cylinders were not firing. The cylinders were getting gas smell and gas coming from the exhuast pipe The plugs were getting spark as was the distributer. Could this be the CPS?? If not do you gurus have an idea what it could be.
Thanks, any help is much appreciated.
May 31, 2010
  Followup from the Pelican Staff: Spark + gas = fire, unless the spark is coming at the wrong time. The computer sounds like it may be misfiring for some reason - it may be the flywheel sensor or the CPS... - Wayne at Pelican Parts  
Dave Comments: Hi, i have a BMW E36 320i that is struggling to fire properly between 2500/3500rpm. It only does this once it has warmed up. Before this range it is fine and once it gets going in this range it suddenly picks up and purrs again. Do you have any idea what could cause this?
March 27, 2010
  Followup from the Pelican Staff: I would check the engine for am isfire under load. It is likely a cylinder or two is misfiring, creating the rough engine feel. - Nick at Pelican Parts  
Greenmonster Comments: Great write up, replaced mine easily on a 96 E36/m52 328i. The connector wires sensor side were all bare. Still runs rough and diagnostics say ECU output is 2.5volts when it should be 5 volts. Could a dodgy sensor from autofactors be the cause or perhaps bare wires on the connector leading to ecu drawing down the power?
November 30, 2009
  Followup from the Pelican Staff: I'm not sure what you mean by bare wires, and yes, crappy sensors from suspect manufacturers can cause more problems then they solve. - Wayne at Pelican Parts  
Tim Comments: In figure 3 the arrow is covering up a hose, what is the name of this hose because as I replace the intake camshaft sensor this hose broke and I don't know what it is
October 19, 2009
  Followup from the Pelican Staff: There's a large hose and a small hose there. The larger one is a camshaft cover / crankcase breather hose. - Wayne at Pelican Parts  
ljdt Comments: I just stumbled across this website. I wanted to learn about a part that was just replaced on my '01 BMW 3 series. Thanks for the education! I feel like I know a little more about my car now.
September 23, 2009
  Followup from the Pelican Staff: Glad we could help. Thanks for the feedback. - Nick at Pelican Parts  
nintz Comments: Have read with great interest the article on camshaft replacement/ timing; and believe the describes the job on a single vanos engine. Is there a discussion on doing a double vanos engine, such as the E39 M52 525i engine.

Thanks!
August 5, 2009
  Followup from the Pelican Staff: It's very similar, but unfortunately, I don't have a write up on this particular procedure at this time. - Wayne at Pelican Parts
