2001 VW Jetta GLS 1.8t o1m <p>Okay, no problems with the car, it just threw a CEL the other day and checked it out it was a P0340. I had it cleared, ran another two days and only then it came back. The car has no problems, no starting problems, no idling problems, no loss in power, or fuel mileage. The check engine light is just on all the time now. I took apart the Camshaft Position sensor, cleaned it off (it wasn't dirty) inspected all the wiring, then had the codes cleared again but it just came back.<p>I dont know what to do, i was told to check the voltage/ohms but i dont know what it should be. I also do not have ready access to VAG-COM.<p>I was also told to check the crankshaft positition sensor, but i dont know where it is, and again what i should be checking for. I would just buy both sensors and change them and not mess with it, but its too expensive. Any ideas?
