P2089 FORD - 'A' Camshaft Position Actuator Control Circuit High Bank 1
- Faulty Variable Camshaft Timing (VCT) solenoid Bank 1
- Variable Camshaft Timing (VCT) solenoid Bank 1 harness is open or shorted
- Variable Camshaft Timing (VCT) solenoid Bank 1 circuit poor electrical connection
When is the code detected?The Powertrain Control Module (PCM) monitors the VCT circuit for high and low voltage. The test fails if the voltage exceeds a calibrated limit for a calibrated amount of time.
- Engine Light ON (or Service Engine Soon Warning Light)
- Long engine start
P2089 Ford DescriptionThe 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 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 rapid movement of the camshaft. Retaining a fixed camshaft position is accomplished by dithering (oscillating) the solenoid valve duty cycle.
