P1388 JAGUAR Meaning

The variable camshaft timing solenoid effects the inlet camshaft timing only. The actuator is a helical spline type, which is engine oil driven. It provides 50 degrees of rotation for camshaft adjustment under different types of engine torque and load conditions.
The comprehensive component monitor (CCM) monitors the VCT position for over-retarded camshaft timing. The test fails when the camshaft timing exceeds a maximum calibrated value or remains in a retarded position.
