Variable Camshaft Timing
WARNING: This page is about a different car, the 2024 Jeep Grand Cherokee L. However, it is still accessible from the selected car via links, so may be relevant.
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.
