Variable Camshaft Timing (VCT) Solenoid
WARNING: This page is about a different car, the 2019 Jaguar XF. However, it is still accessible from the selected car via links, so may be relevant.
The VCT solenoid is located on the chain cover and secured with 2 screws.
The VCT solenoid is controlled by a Pulse Width Modulation (PWM) output from the PCM. The PCM uses signals from the CMP sensor and determines the position of the VCT actuator which has a direct interface with the exhaust camshaft.
The VCT solenoid incorporates a spindle that acts on the spool valve in the VCT actuator to advance and retard the exhaust camshaft timing.
