Advanced VCT CEL
I have this code in my car, can someone explain this to me and how can I fix this?
|
The SVT uses variable valve timing by advancing the cam.
If you are lucky, it might just be the cam position sensor gone bad. |
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. |
So worst case I'm looking at a sensor for the cam?
|
Has the t-belt ever been changed? How many miles are on the car? If it's never been changed and it's got high mileage I'd be more concerned about that code, it could have jumped time or lost a tooth or something, or could be as simple as a sensor.

The cheapest and easiest possible cause is the sensor. Worst case is the camshaft VCT assy (that I believe ford has discontinued). It sounds like you need to find somebody else to troubleshoot the problem. |
I'd check the t-belt asap IMO.
