Camshaft Sensor Position Sensor Replacement help

[brandonb93]

Hey guys, new to the forums so I'm not sure if this has been covered in a previous thread for the b7s but, I have a 2006 b7 and am running into some issues. The car recently had some work done to it, with both timing belts replaced and tuned correctly (I'm assuming). Although, the engine seems to have some shaking to it and it idles quite low (barely below 1,00 RPMS). In addition the car doesn't seem to have a whole lot of power to it, its quite slow to accelerate as if it's misfiring. Yet, after it reaches 1,500 rpms or so it runs perfectly smooth and especially better when its on the freeway and at higher speeds. I had the ECU scanned, and it came up with a P0300 random misfire code subsequently giving it misfire codes for all 4 cylinders. Also, it gave me a p0340 camshaft position sensor (bank 1 or single sensor) code. The spark plugs are new on the car, the coils are fine, thus I'm fairly sure it's either the camshaft position sensor or the timing is off by a tooth. Although, it runs fairly well so I would assume it would run much worse if the timing was off.


SO, I was hoping someone could point me to a guide on replacing the CPS, or at least a diagram/picture of the location of the CPS. Thanks!

Both timing belts? Sounds like the timing is off a tooth or so.

Would also be interested in knowing exactly where this is!

I would be checking the timing at the cam and crank are correctly aligned before spending $ on a new sensor, lack of power after a belt change usually indicates incorrect position.

IIRC the cam pos sensor is forward of the intake runner for cylinder 1. Before spending on the CPS, I would verify timing as stated above as well as look at cam follower. I thought a fair number holed cam followers also had CPS code.

^That's it. It is held in by a single bolt below the connector. Never tried but it's probably a pain in the ass to change. Pulling the intake manifold would probably help a lot with access to it.

Edit: The bolt is a triple square IIRC.
