(B) Camshaft Position Actuator Control Circuit High

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 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.

Cause:
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

Symptoms:
Check engine light
Long engine start
