Code P1381 Mercury Description

The P1381 diagnostic trouble code (DTC) for Mercury vehicles indicates a problem with the Variable Cam Timing (VCT) system on Bank 1. The VCT system is responsible for adjusting the timing of the camshaft to optimize engine performance and fuel efficiency. When the cam timing over-advances on Bank 1, it means that the camshaft is rotating too far ahead of the crankshaft position, causing an imbalance in the engine's timing.
