Variable Camshaft Timing Solenoid
WARNING: This page is about a different variant/trim than selected.
Each VCT solenoid is located on the timing chain cover and is secured with 2 screws. The VCT allows for the standard camshaft lobe profile to be advanced or retarded for optimum combustion.
The VCT solenoids are controlled by a PWM output from the PCM . The PCM uses signals from the CMP s and determines the position of the VCT actuators. The VCT actuators have a direct interface with the intake and the exhaust camshaft.
Each VCT solenoid incorporates a spindle that acts on the spool valve in the VCT actuator to advance and retard the exhaust camshaft timing.
