Code P1380 – Description for Mercury
The diagnostic code P1380 for Mercury vehicles indicates a malfunction in the Variable Cam Timing (VCT) system’s solenoid “A” circuit. This system is designed to adjust the camshaft timing, thereby optimizing engine performance, fuel efficiency, and emission reduction. The VCT solenoid regulates the oil flow to the camshaft phaser, allowing precise adjustment of its timing.
