P 1383 cougar 2000 - 2000 Jaguar S-Type

P 1383 Variable Cam timing over-retarded (Bank 1) meaning the comprehensive component monitor (CCM) monitors the VCT position for over - retarded camshaft timing . The test fails when when the camshaft timing exceeds a maximum calibrated value or remains in an retarded position.
Cause :
* Cam timing imprperly set * Continuous oil flow to the VCT piston chamber
* VCT solenoid valve stuck open.
* Camshaft advance mechanism binding (VCT UNIT)

Hope that helps
