Variable Valve Timing (VVT) is used to vary engine performance and enhancements. On dual cam systems, the PCM controls the amount of variance on With the signal received from the PCM, the solenoids actuators open allowing engine pressure to enter either one of the two passages;

The purpose of variable valve timing (VVT) is to help increase the engine's volumetric efficiency and limit the exhaust gasses produced by the vehicle. Using an actuator test a technician can actuate a variable valve timing solenoid and observe a change in the audible note of the engine and/or

VCT Solenoid: How Does The VCT Valve Work? Before the working process can begin, there are a number of The variable valve timing system depends on a solenoid to control the oil flow as it is engaged. Test-driving your car will be possible once you have installed the new part in its place.

Variable Valve Timing (VVT) is a technology that's used on many late model engines to improve fuel HOW Varible Valve Timing Works. There are a variety of different VVT systems in use today. With on-off solenoids, you can test the continuity and/or resistance of the solenoid with a DVOM

Hydraulic Variable Valve Timing Testing and Validation. This hydraulics based variable valve timing system is capable of controlling an engine valves lift height and infinitely varying When the desired valve lift is reached, stage two begins by energizing solenoid 2 to pressurize the rear

How do you test a variable valve timing solenoid? As you likely know this reassembly can be a lot of work so a friend of mine has created a test rig that uses air pressure, rather than oil pressure, to test operation of the solenoid and VVT itself.
