P1383 Cam Timing Advance is excessive.
The comprehensive component moniters ( CCM ) the VCT position for over retarted camshaft timing. The test fails when the camshaft timing exceeds a calibrated value or remains in the calibrated position.
Causes
- cam timing improperly set
- continous oil flow to the VCT piston chamber
- VCT solenoid stuck open
- camhaft advance mechanism binding ( VCT unit)
