Essentially, the PCM isn't getting the correct signal from either the camshaft position sensor (bank 2, since it's a V6) or there's a problem with the crank sensor's signal affecting the overall timing synchronization. This is a serious code that can prevent the engine from running properly or at all.
To diagnose and resolve this issue, a mechanic should:
* Inspect the wiring harness leading to both the camshaft position sensor (bank 2) and crankshaft position sensor for any damage, corrosion, or loose connections.
* Check the camshaft position sensor (CMP sensor) and crankshaft position sensor (CKP sensor) for proper operation and continuity. Often, replacement is necessary.
* Verify the PCM's functionality. While less common, a faulty PCM can cause this code. This is typically diagnosed after checking the sensors and wiring.
* Check engine oil level and quality. Low oil or very dirty oil can affect sensor readings.
Don't attempt complex repairs yourself unless you have experience working on engine management systems. Misdiagnosis can lead to further damage. Take your Concorde to a qualified mechanic for proper diagnosis and repair.
