Rostra Precision Controls 79-0125 Variable Valve Timing (VVT) Solenoid

The Rostra Precision Controls 79-0125 is an engine variable valve timing (VVT) solenoid, also called a VVT oil control solenoid or cam phaser solenoid. It is an electrically controlled part of the engine's variable valve timing system.

What it does:

• Controls the flow of engine oil to the valve timing actuator, which adjusts camshaft timing
• Helps the engine management system change valve timing as operating conditions change

Use it to replace a worn or failed variable valve timing solenoid.
