P0341 — Camshaft Position Sensor "A" Circuit Range/Performance Bank 1 or Single Sensor

I’ve been seeing quite a few VW/Audi vehicles with 1st and 2nd generation 2.0 Common Rail TDI Engines come in complaining about an intermittent no start or MIL light on with the vehicle also not starting and/or stalling. Usually after a scan, the fault that shows up almost every time is P0341 Camshaft Position Sensor Circuit Range. If you have worked on one, cam position sensor is located behind the cam sprocket on the timing belt side and has a pigtail with connector that runs along the block and sits on a bracket behind the oil filter cooler/housing.


If you follow the main engine harness that runs down the side of the intake manifold, you will notice it turns and loops back around the oil filter housing. 


Check and make sure that the harness is not touching and chaffing against the edge of the oil filter housing. I’ve seen it rub just enough to show a slight glimmer of the wire causing a short in the wiring causing the engine to not start or stall out when the camshaft position sensor signal is dropped to the ecm.



In this example it is more apparent, but I have seen some cases where it barely wears through the protective sheathing around the harness. Wire can be fixed or replace the complete harness.

The same location can also cause a P0651 - Sensor Reference Voltage B - intermittent fault. This capture is from a 2011 Jetta Sportwagen that had a hesitation during acceleration. I captured it during a wiggle test while the engine was running to narrow down the general area.
