On the 2002 GMC Envoy, the powertrain control module (PCM) uses the crankshaft position (CKP) sensor and the camshaft position (CMP) sensor information to monitor the correlation between the crankshaft and camshaft positions. If the deviation between the crankshaft and camshaft position exceeds a calibrated amount DTC P1345 will set.
The P0014 is pointing to a problem with the Camshaft Position Actuator Solenoid. This solenoid is used in the variable valve timing system. The solenoid will advance/retard the camshaft position to provide the best possible fuel economy and performance for any given driving condition.
So, first thing to check here will be the ignition timing. The timing chain will need to be inspected for any signs of ‘stretching’. The timing marks will need to be checked and make sure they are set perfectly. And misalignment can set these codes.
If the timing is still set perfectly, then suspect the Camshaft Position Actuator Solenoid has failed and will need to be replaced. The solenoid is located on the front, passenger’s side of the engine.
