     The cam position sensor is critical to the proper functioning of the engine management system in its timing of engine events. The sensor delivers information on the position of the camshaft that actuates the engine’s intake valves to the computer, which uses that information to deliver fuel and spark at the correct time.

     As you can imagine, if the air/fuel mixture in each cylinder doesn’t get lit off by the spark plug at the correct moment, the engine just won’t run right. Like all modern engines, the 1.8T relies on a host of sensors like this to operate. On the one hand, it means you can no longer tune your engine with a screwdriver. On the other, these kinds of sensors provide very accurate and robust information to the engine, allowing modern computerized engines to operate much more efficiently than older engines with improved driving characteristics and power output. In essence, computerized engine management made turbocharged engines like our 1.8T much more viable for auto manufacturers to build and sell.

     Fortunately for us, the cam position sensor in the 1.8T sensor is conveniently located and fairly easy to change. In the photos below I have moved the radiator support panel into the service position, but I don’t think it’s necessary to do so.
First, remove the upper timing belt cover at the front of the engine.
Figure 1
First, remove the upper timing belt cover at the front of the engine. Simply release the two clips holding it in place. Ignore the fact that the wiring to the cam position sensor is already disconnected in this photo. Below I’ll show you what it looks like and how to disconnect it.

This is the metal clip on the other side of the cover.
Figure 2
This is the metal clip on the other side of the cover. You’ll also need to move the two hoses that run across the face of the cover. You can simply slip them out of their supporting clips and pull the cover upward to remove it.
Large Image | Extra-Large Image
With the cover removed it’s easy to see the sensor.
Figure 3
With the cover removed it’s easy to see the sensor. Use your flat-blade screwdriver to pry the metal clip up and release the electrical connector.
Large Image | Extra-Large Image
Use a 10mm socket and ratchet to remove the two bolts holding the sensor to the cylinder head.
Figure 4
Use a 10mm socket and ratchet to remove the two bolts holding the sensor to the cylinder head.
Large Image | Extra-Large Image
With the sensor removed, note the green-grey metal piece that remains attached to the cylinder head.
Figure 5
With the sensor removed, note the green-grey metal piece that remains attached to the cylinder head. Also note the gaps in the piece that alternate with portions of the cup-shaped “wheel” that remain, forming a set of “teeth”. As this metal wheel spins along with the intake camshaft, the teeth pass through a gap in the functional part of the sensor. Depending on whether that gap is blocked by the metal teeth or not, the sensor alters the voltage signal that it sends to the engine computer, which interprets the voltage to determine the position of the camshaft.
Large Image | Extra-Large Image
This close-up of the inside of the sensor shows the gap through which the metal teeth pass to indicate the position of the camshaft.
Figure 6
This close-up of the inside of the sensor shows the gap through which the metal teeth pass to indicate the position of the camshaft.
Large Image | Extra-Large Image
Keep the face of the sensor parallel to the mating surface on the head as you reinstall it to keep the teeth from obstructing the installation.
Figure 7
Keep the face of the sensor parallel to the mating surface on the head as you reinstall it to keep the teeth from obstructing the installation.

Secure the sensor with the two 10mm bolts you removed earlier.
Figure 8
Secure the sensor with the two 10mm bolts you removed earlier. Tighten them to 7 ft-lbs.

The trickiest part of this job is reinstalling the timing belt cover, particularly where it interlocks with the lower timing belt cover.
Figure 9
The trickiest part of this job is reinstalling the timing belt cover, particularly where it interlocks with the lower timing belt cover. Get the covers locked together correctly first and then you can snap the top back onto the top of the valve cover. Last, reconnect the wiring to the sensor and replace the vacuum and coolant lines that run across the upper timing belt cover.

Comments and Suggestions:
shaker Comments: change the sensor but still when put on computer shows same problem that sensor is incorrect assignment or smth like that.
November 27, 2014
  Followup from the Pelican Staff: Could be the sensor or a timing issue. - Nick at Pelican Parts  
Mo Comments: I have a 2007 audi A4 2.0T that bogs out when I accelerate and wants to die out when at a stop or low speed. Did a old scan and it read crankshaft sensor. I replaced the sensor and it's still acting up. What do you recommend?
November 26, 2014
  Followup from the Pelican Staff: I would perform a fuel delivery system test. Check fuel pressure, volume and quality.
- Nick at Pelican Parts
 
Kevin Comments: I have a 2001 audi a4 1.8t Quattro 5spd, it has been making a weird chattering type noise during idle and it has a check engine light on for a camshaft position acuator a- bank one timing over advan... I have no clue what if it's the sensor or something else, please help
October 29, 2014
  Followup from the Pelican Staff: Could be a bad actuator or an issue with the camshaft or camshaft timing. Inspect the actuator an camshaft timing / lobes. - Nick at Pelican Parts  
AudiSchmaudi Comments: Hi, have an 08 Audi A3. Had a breakdown and engine cut out and wldnt start. Garage said it was cam sensor, changed it and cam belt, water pump, coolant - big bill. Took it home 1 mile, next morning I now have a fault code coming up - indicating coolant is too low. Coolant level looks ok to me I know nothing! Any thoughts? Is this garage ineptitude or coincidence?!
October 23, 2014
  Followup from the Pelican Staff: Check if the coolant level sensor under the reservoir is plugged in. - Nick at Pelican Parts  
Omar Comments: sir, I have passat 99, got a code P1338 referring to cam shift sensor. How do I know which bank is 1 or 2 ? Where are they located ? thank you
September 26, 2014
  Followup from the Pelican Staff: What engine is in your vehicle? You may have only one. - Nick at Pelican Parts  
Pandaradu Comments: Thx, Nick i had resolve it. It was my timing belt. Was not put the correct way. Have a nice day :
August 21, 2014
  Followup from the Pelican Staff: Thought that would be it. Glad to help. - Nick at Pelican Parts  
Pandaradu Comments: The timing belt is not mounted the correct way?
August 16, 2014
  Followup from the Pelican Staff: Could be the issue. - Nick at Pelican Parts  
Pandaradu Comments: Thx, Nick. But the engine can run perfectly if the engine timing is not
Ok?
August 16, 2014
  Followup from the Pelican Staff: Yes, if it is off slightly due to worn components. - Nick at Pelican Parts  
Pandaradu Comments: Hello everybody. I have an audi a4 1.8 t. I just changed the distribution kit and timing belt and water pump. After my mecanic had changed the belt. The car runs perfectly. But the camshaft sensor appears to be the problem. Before the belt change everything was ok on tester. And now the check engine is on. I am from hungary. I reminde you the car runs perfect but the check engine light is on
August 14, 2014
  Followup from the Pelican Staff: DOuble check engine timing. My guess is it is not correct. - Nick at Pelican Parts  
jas Comments: ok I will check the timeing. and also when I put new spark plugs old ones didn't look that bad. I crank it few times. . and pull the spark plug out it seemed like it wasn't getting any fuel to plugs.... but injectors getting power.
August 3, 2014
  Followup from the Pelican Staff: Ok, let me know what you find. - Nick at Pelican Parts  
jas Comments: can someone help me please. 1999 2.0 jetta. I just die on me at work yard. I had a scanned it showed up cam position sin. so I repalce that it still wount start. it got fuel. it got spark. I cranked it the moter about 10 time. I also discount the battery for while. does that can cause the car over flood and fault the spark plugs. any one can help me..
August 1, 2014
  Followup from the Pelican Staff: If you have spark and fuel, it has to be compression. CHeck compression. If it is off, check engine timing. - Nick at Pelican Parts  
JB Comments: 2000 VW Golf 2.0, new head gasket, water pump, timing belt, all less than 50 miles ago. Car stalled out, would start but stall if given any throttle. Took to local garage, no CEL, they replaced fuel filter, fuel pump, and ignition coil... Now it won't even start!!! Any thoughts?
July 27, 2014
  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. Are there any fault codes? Once you figure out what is missing, it will be easier to diagnose.

Silver Comments: Hello im trying to find the camshaft position sensor on my 2001 jetta 2.0l but having no luck a little help on where to find it and how to take it off
July 17, 2014
  Followup from the Pelican Staff: I believe it is located behind the camshaft pulley, mounted to the cylinder head. - Nick at Pelican Parts  
JUST SAYIN' Comments: I FOLLOWED THIS WRITE-UP FOR MY 2001 NEW BEETLE 1.8T. FOR MY TRANSVERSE MOTOR IT WAS NOT NESSESCARY TO REMOVE THE TIMING BELT COVER . JUST UNCLIP IT IN FRONT AND BACK THEN SLIDE BACKWARD ENOUGH TO CLEAR THE 2 10 MM BOLTS FOR REMOVAL . REMOVE THE SENSOR BEFORE DISCONNECTING THE ELECTRICAL CONNECTION . ONCE SENSOR IS UNBOLTED AND SLID UP ,IT IS THEN MUCH EASIER TO PULL THE WIRE KEEPER OUT TO DISCONNECT .ALSO
RECLIP IT BEFORE RE-INSTALLING THE COVER , AS IT IS EASIER THIS WAY.....I ALSO DISCONNECTED THE BATTERY AS THE FIRST STEP.
June 21, 2014
  Followup from the Pelican Staff: Thanks for the additional info and feedback. We appreciate it.
- Nick at Pelican Parts

thank you
June 3, 2014
  Followup from the Pelican Staff: This is a fault code for camshaft timing. The timing could be off or there is a faulty component. - Nick at Pelican Parts  
GARRY Comments: NICK ,MY SCAN ON MY NEW BEETLE 1.8T IS P0030 / YOU SAID MY PROBLEM COULD BE THE 02 SENSOR REPLACED OR THE WIRING /SHORT CIRCUIT / OR YOU SAID COULD BE THE DME ???? COULD YOU TELL ME WHAT A DME IS ? THANKS
May 17, 2014
  Followup from the Pelican Staff: The DME is the engine control module. - Nick at Pelican Parts  
GARRY Comments: NICK , THANKS FOR ALL YOUR HELP . AFTER GETTING A CEL LIGHT COMING ON OFTEN , MY BEETLE 1.8T SCAN READ HEATER CONTROL
CIRCUIT , BANK 1 SENSOR 1...POSSIBLE FAILED H02S12 ? POOR ELECTRICAL OR POSSIBLE SHORT CIRCUIT . POSSIBLE VAC LEAK . CHECKED IT ALL OK.I ORIGINALLY THOUGHT IT WAS MY MAF AND REPLACED IT SOLVING LUMPY IDLE , REPLACED BOTH 02 SENSORS. CAR RAN GOOD BUT CEL CAME BACK ON . I READ SOMEWHERE THAT A BAD FUEL FILTER COULD CAUSE CEL IF NOT REPLACED REGULARLY.
I REPLACED THE FUEL FILTER AFTER HAVING ORDERED THE PURCHASED A CAM POS SENSOR AND ENGINE SPEED SENSOR .I HAVE NOT INSTALLED THE CAM POS SENSOR OR THE ENGINE SPEED SENSOR AND AFTER FILTER REPLACEMENT I GET NO CEL AND CAR SEEMS TO RUN NEARLY PERFECT .DO YOU HAVE A DIY ON TEST PROCEDURES FOR
TESTING THE 02 HEATER CIRCUIT ? I READ THAT IT IS RELATED TO
THE FUEL PUMP RELAY SWITCH WHICH I HAVE PURCHSED BUT NOT INSTALLED . ALSO WHAT IS THE DME YOU MENTIONED RELATING TO THE 02 SENSOR ? AND THE LAST STUPID QUESTION / NOW WITH NO CEL SHOULD I INSTALL THE CAM POS SENSOR ,ENGINE SPEED SENSOR OR FUEL PUMP RELAY ? I AM GETTING A PRE IDLE KICK DOWN
LUMPINESS DURING COLD START..... P.S. CAR HAS 185 K ON IT AND HAVE REPLACED MANY SENSORS ,PARTS ,TO BRING RESTORE CAR.
May 15, 2014
  Followup from the Pelican Staff: We do not have a DiY for that procedure. To test the heater, check that the heater wires at the o2 are functioning. You should have power and a ground. One of which will be cycling to run the heater as needed. - Nick at Pelican Parts

GARRY Comments: WHAT IS A HEATER CONTROL CIRCUIT BANK 1, SENSOR 1 ON A 2001 BEETLE 1.8T / P0030 / HOW TO FIX ?
May 13, 2014
  Followup from the Pelican Staff: The code refers to a fault in the o2 sensor heater circuit. It could be the sensor, the wiring or the dme. You will have to check heater operation and test the circuit. - Nick at Pelican Parts  
fendersfender Comments: 2000 beetle 1.8l seems to have noisy valvetrain after rebuild. very poor idle and timing jumps all over at idle only. higher rpms the car runs smoothly and timing is constant. any help is appreciated

Nick Comments: I have an Audi A4 Quattro and the engine generally runs fine cold and also when reaches the optimal running temperature. After driving a while I park the car then start the car back up after a few minutes and the car runs rough for a while then after a bit it goes back to running normal again.
What are your thoughts? Is it the Camshaft Position
Sensor?
April 7, 2014
  Followup from the Pelican Staff: Not sure, is there a fault code for the camshaft sensor. I would check the engine for a misfire when it is running rough. Isolate the cylinder, then check spark, fuel and compression on that cylinder. - Nick at Pelican Parts  
daytonagti Comments: i have a 01 gti 1.8 aww engine. i changed the cam position sensor and now it cranks but doesnt start the first 2 times trying but will start the third time, sometimes the second. It did not do this before, replaced it because it was throwing a code for the cam position sensor. any thoughts??
March 23, 2014
  Followup from the Pelican Staff: Is the fault code still present? Or a new one stored? I can't help without knowing what is missing from the system when you are trying to start it.

Dale Comments: Thanks for your help. Come to findout the rear tensioner for the advancement on the intake side had broke. The lower guide had snapped causing more slack in the chain and allowing the intake valves to smack the pistons. The first piston it completely broke from one valve to the other.

dale Comments: Well i havent comfirmed the timing has jumped at all but the belt is still in good condition from what i can see and was changed about 40,000 miles ago i was told by the previous owner. When i hooked the scan tool up to it it said something about the cam retardation not in its value. I was hoping it was just a sensor but im believing it is bent valves. On another note. I can get another passat that has been wrecked but its a 2000 with a 2.0 and 5speed and im debating if it would be worth while to swap motor and comp. Is the 2.0 the same bolt pattern as the 1.8? Thanks for your help.
March 16, 2014
  Followup from the Pelican Staff: The 1.8 and 2.0 are different. The cam angle code was referring the jumped belt. I would reset the timing and check engine compression. It might be OK. - Nick at Pelican Parts  
dale Comments: My motor has 250,xxx on it and was wondering if there is anything that would make it stop running out of the blue.. its a 2002 vw passat with the 1.8t and it detected random mutipule misfires and the cam retardation was out of value. When it cranks it almost sounds like it has no compression... Any clues?
March 6, 2014
  Followup from the Pelican Staff: The timing belt may have failed. That would cause engine damage and a no start. - Nick at Pelican Parts  
Teddy Comments: My engine runs great but still have the p1340 code. Change the crank position sensor last year. Could the cam sensor be the culprit.
March 2, 2014
  Followup from the Pelican Staff: The cam sensor could be the issue. It could also be engine timing. - Nick at Pelican Parts  
BJ Comments: The error code is p001 camshaft position censor
February 28, 2014
  Followup from the Pelican Staff: Your code is missing a digit. Should be one letter followed by 4 numbers. - Nick at Pelican Parts  
BJ Comments: Hi...question i have a 01 Volkswagen passat 1.8t it keeps giving me a camshaft position sensor code I have changed the sensor twice and also the cam chain tensioner and check the timingwhich is right and the code came back on after I did all that and it's running rough any ideas what it could be?
February 27, 2014
  Followup from the Pelican Staff: If the sensor has been replaced and engine timing is correct, not much else can cause a cam sensor code. However, you did not mention the code number, so I am shooting in the dark. - Nick at Pelican Parts  
matt Comments: ive got a 2002 volkswagen jetta 2.0l 4cyl 5 speed manual . is it the same process to change the camshaft position sensor as shown above?

Cvwm Comments: My 02 vw jetta is throwing a code the states a CPS. I have looked at a few forums and some are saying I should use "sea foam" and flush everything out before getting into the sensor... What should I do. On a budget
February 11, 2014
  Followup from the Pelican Staff: What fault code? If it is a sensor code, I am not sure how cleaning the engine would remedy it. - Nick at Pelican Parts  
JRl Comments: Strange no start condition. Have fuel,air,spark. Injecting ether into a cylinder does little. It started after removing the TB cover. Suspect CPS. Harness test shows 5v on pins 1&3. Codes from Vag com clearned so little new info to work with. Code 16396 - Bank 1: Camshaft A IntakeP0012 - 35-10 - Advance Setpoint not Reached Over-Retarded - Intermittent was pulled prior to clearing codes. Any thoughts? Mine are it has to be injecting at the wrong time.
January 18, 2014
  Followup from the Pelican Staff: I would check compression and mechanical engine timing. Sounds like it may be off. - Nick at Pelican Parts  
stevie b Comments: Hi All. Wheres the crank sensor located on vw golf turbo 2001 'Y'
January 10, 2014
  Followup from the Pelican Staff: At the front of the engine, next to the oil filter near the transmission bell housing.- Nick at Pelican Parts  
John Comments: Coolant temp sensor that would be the thermostat right?

But is that relevant to the crankshaft position sensor being faulty/ becoming faulty? could let's say its about the fuel injector leak or whichever of the ones you stated, so could a faulty "x" cause the crank sensor to stop working and not sending current to the coils or some sort of effect like that? Thank you for your support and I kinda figured it would be most useful to post questions here just wanted your opinion about it. Thanks again and no my problem is still not solved I don't have a lift in my driveway to lift the car and change the sensor so I'ma have to take it to garage I think : less experience for me but... I need my car :s lol Aight Thanks brother have nice holiday season ;

John
December 22, 2013
  Followup from the Pelican Staff: We cannot really get into what could be wrong without some data. At this point, it is a dice roll.

The coolant temp sensor is a sensor that measures engine coolant temp. It is not the thermostat. Neither could cause the crankshaft to stop working. - Nick at Pelican Parts
 
John Comments: Agreed Nick that goes pretty much without saying...

Problem Is all that was fine up until the engine "flooded" I "know" this because we managed to get it to start 2-3 times removing one plug and firing up the engine to blow out/burn the excess of gas before it stopped firing up for good....its only after that that I got myself a scanner and pulled the codes... Now I know this isn't some "fix my car for me please" forum and I would be extremely grateful if there was a way we could talk about this Nick. if you'd rather me keep posting on this page as it may/may not affect other people as well, just let me know

mr.john187@gmail.com : thanks for quick reply will recommend pelicanparts to all my ppl Thx again : Have a nice day!

  Followup from the Pelican Staff: If the engine is flooding, you could have an issue with the coolant temp sensor, too high of fuel pressure, or leaking fuel injectors.

Posting here is the best way, then others benefit from the discussion. - Nick at Pelican Parts
 
John Comments: "In the photos below I have moved the radiator support panel into the service position, but I don’t think it’s necessary to do so."

It isn't.... so long as you dont lose a bolt in the timing chain path then you have to do it to go GET the ****** bolt.... other than that I have managed to change the sensor no problem I just cannot start the engine for sh*t now.... but I don't know if it is even related since I changed it because the car wouldnt start in the beginning soo.... as you may guess I'm a little screwd... :S

  Followup from the Pelican Staff: You need to know that the basics--compression, fuel supply, spark are (or are not) correct before worrying about the camshaft sensor. - Nick at Pelican Parts  
Niftyfifty Comments: Many thanks. I know it's a simple job but it's nice to see how it's done, especially when you're doing it outside in November. Why is it that these things always happen when it's either dark, cold or raining ?!

  Followup from the Pelican Staff: If you have the 1.8l engine, yes. - Nick at Pelican Parts  
miguel Comments: Can someone help me please? I cant get the camshaft sensor all the way in. There are pieces of metal flanged around that prevents it from alignin gto the bolt holes.

Please help me.

  Followup from the Pelican Staff: Is the metal a heat shield? You may have to loosen the other fastenrs securing the heat shield to the engine, then install the camshaft sensor. - Nick at Pelican Parts
