This DTC code?

P1381 - Variable Cam Timing Over-advanced (Bank 1)
The comprehensive component monitor (CCM) monitors the VCT position for an over-advanced camshaft timing. The test fails when the camshaft timing exceeds a maximum calibrated value or remains in an advanced position.
Causes:
Cam timing improperly set
No oil flow to the VCT piston chamber
Low oil pressure
VCT solenoid valve stuck closed
Camshaft advance mechanism binding (VCT unit)
P1381 DTC is a check of the VCT unit. Testing should not include electrical checks. Diagnostics and repair for the VCT unit are located in the Workshop Manual.
