Need help locating the cam shaft position sensor Bank 1 on my 2001, 986 S. Any pictures would be a great help.

Thank you so much. Bank 1 is on the passenger side of car and sensor is to the rear of the head? Is all that correct?

[JFP in PA]

Sounds correct.

This position sensor is on the front of the engine on the passenger side. It is readily visible and accessible by removing the front engine cover in the passenger compartment. The Bank 2 sensor is on the left bank on the rear of the engine and is accessed by removing the air tube from the air filter box to the engine.

Thank you so much, I hope to get to it this coming weekend. Do I need any "Special" tools?

Nothing special other than metric box end wrench or socket to take off the front engine cover holding bolts and a screw driver, but for the front it is all easy and does not need a super flexible wrist to get to the sensor. You might want to use dielectric grease sparingly on the electrical plug contacts. Put a little in the female side of each contact in the plug.

Engine cover is removed. Looking at the engine from the seating compartment, the cyclinder head on the right (behind driver, Bank 2) has a cam postion sensor clearly visible to the front of the engine. Does this mean that on the cyclinder head on left (behind passenger, Bank 1) the cam position sensor will be to the rear of the car on the head?

Mine is a 2003 Boxster and I have a cam position sensor on the left rearbank and on the right forward bank behind the passenger seat. If you are looking at the position sensor on the left forward end behind the driver then you will find the other one on the rear of the right bank on the passenger side. Of course with the forward engine cover removed you should be able to see if there is also a position sensor on the right side front, just behind the passenger seat. If there is one there it will surprise me because they normally alternate one side forward with the opposite side on the rear.

I'm confused. I've read front left and right rear and front right and left rear. Access thru front cover and access thru top cover. Is this discrepancy due to differences in years and models? In the US the drivers side is always the left. My car is a 2000 986 2.7. I am having trouble spotting it where the Bentley says it is (front left, right rear. Antone replaced these on a 986?
