Variable Camshaft Timing

The Variable Camshaft Timing (VCT) system uses a Variable Valve Timing Solenoid (VVTS) to direct oil pressure into the camshaft phaser assembly. The camshaft phaser assembly advances and/or retards camshaft timing to improve engine performance, mid-range torque, idle quality, fuel economy, and reduce emissions. The VVTS is located under the intake manifold.
