If not voltage at camshaft position sensor then you need to check wiring between camshaft position sensor and ECM. If wiring is good then the ECM needs to be replaced. Here is a wiring diagram to help with testing, let me know if you have questions. Thanks.

Hello, my name is***** and thanks for your question.

The cam sensor is a variable reluctance sensor. There won't be any voltage from the PCM, it does not need voltage to operate. When the armature passes through the magnetic field it generates a small A/C voltage which is sensed by the PCM. Is the vehicle generating a P0340 code?

Does the engine run or sound like its out of time when cranking?

Is this the 12 valve engine or 24 valve engine?

The book says you should have 12 volts at the cam sensor? Not possible.

I think your next step is a compression test, need to rule out base engine first. What all has been tested or replaced to this point?
