Code P0011 Mercury Description

The Variable Camshaft Timing (VCT) solenoid valve is an integral part of the VCT system. The solenoid valve controls the flow of engine oil in the VCT actuator assembly. As the Powertrain Control Module (PCM) controls the duty cycle of the solenoid valve, oil pressure/flow advances or retards the cam timing. Duty cycles near 0% or 100% represent the rapid movement of the camshaft. Retaining a fixed camshaft position is accomplished by dithering (oscillating) the solenoid valve duty cycle. This Diagnostic Trouble Code (DTC) sets when the Variable Camshaft Timing position is over-advanced. This DTC sets when the camshaft timing exceeds a maximum calibrated value or remains in an advanced position.
