Diagnostic Aids
WARNING: This page is about a different car, the 2004 Pontiac Sunfire and 2004 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
- An intermittent fault in the CKP circuits may cause the PCM to resync the cam and may set this DTC. If the PCM is resyncing the camshaft, the CMP Resync Counter on the Scan tool will increment with the engine running.
- An intermittent short to voltage on the camshaft position signal can set this DTC. A direct short to voltage on the camshaft position signal circuit will set P0340, as there will be no change in the camshaft position signal input.
- Electromagnetic interference (EMI) may also set DTC P0341. Inspect the wiring harness for damage. If the harness appears to be OK, observe the CMP resync counter on the scan tool while moving connectors and wiring harnesses related to the camshaft position signal. If the CMP resync counter still does not count, while observing the scan tool, operate any non-engine related electrical components on the vehicle. A change in display will indicate the location of the malfunction.
If this DTC is determined to be intermittent, refer to Intermittent Conditions .
