The Variable Valve Timing system is designed to increase engine output at a certain RPM / load range while maintaining fuel efficiency. This is accomplished by retarding exhaust valve closure. The PCM uses values from the throttle position sensor (TPS) & MAP sensor along with RPM to determine when to activate the system.

The Variable Valve Timing Solenoid is a key part in this system. It controls the oil pressure which engages an actuator to activate the cam timing change. A failure of this part will result in a complete failure of the VVT system.

Our electrical and electronic parts are subject to strict quality testing.

Parts cannot be returned after they have been installed. Contact us with any questions before installing the parts.

Did the job.
This solenoid corrected the issue with my truck. It runs much better now and there is no check engine light. It fit perfectly and was easy to install. And it was $13 cheaper than the local parts stores were charging.
