2009 Saturn aura xr I got a P0013 code to replace camshaft. Piece was replaced but engine light continues to stay on even after replacing this piece twice! What could cause this problem?
With this trouble code the problem is in the wiring going to the sensor. Not the sensor itself. Inspect the wiring for damage or breaks. HTH. - Jim
Dirty oil can give this code also as well as the oil solinoid sticking. Especially if the car sat for an extended period.
