The Variable Camshaft Timing (VCT) oil control solenoid is an electrically controlled hydraulic valve that directs engine oil to the camshaft phaser. Once the PCM transmits a signal, the solenoid moves a valve spool, directing oil into the camshaft phaser cavity. This action changes valve timing by either inducing an advance or retard condition. The camshaft is, thereby repositioned in relation to crankshaft timing and allows for optimum engine performance and lower emissions.
Removal & Installation
- Remove the LH or RH valve cover, as applicable
- Remove the bolt and the Variable Camshaft Timing (VCT) oil control solenoid.
Installation is the reverse of the removal procedure. Tighten the VCT oil control solenoid to 10 Nm (89 inch lbs.).
- Turn the ignition switch to the OFF position.
- Disconnect the VCT1 or VCT2 sensor electrical connector, as applicable.
- Measure the resistance between VCT + and VCT - on the component side.
If resistance is not within 5-14 ohms, replace sensor.
