The CPS sensor is relatively easy to remove but very difficult to photograph while in the motor so I have included thisPicture with the front of the car removed to show just where it is.

The CPS sensor is relatively easy to remove but very difficult to photograph while in the motor so I have included thisPicture with the front of the car removed to show just where it is. Note; you do NOT need to remove the front the car to change the CPS sensor. With the front of the car removed you can see the wiring harness connector (yellow arrow) is located in a clip on the right side of the oil filter while the sensor is located on the left side of the filter. Before you remove the sensor it is a good idea to clean around the sensor area as best as you can. There tends to get a lot of oil and grim build up in this area and you do not want it getting into the motor and you want to make sure the new sensor sits flush. Remove the harness from the clip and disconnect. Use a 5mm Allen and remove the single Allen screw holding the sensor in place. You may need to use a large screwdriver to help pry the old sensor out.

This photo illustrates the angle from below. I have highlighted the sensor wire and sensor in red (red arrow). You will need to work between the secondary air pump (yellow arrow) and the oil filter (green arrow) to replace it.

Here is the new sensor.
Figure 3

Here is the new sensor. Make sure that the old O-ring (red arrow) came out with the sensor you removed. Clean the engine block around where you are inserting the new sensor, lightly lubricate the O-ring on the new sensor and install. Installation is the reverse of removal.
