The VVT solenoid regulates the flow of pressurized oil to the cam phaser / VVT sprocket, adjusting valve timing in response to real-time engine load and speed to support fuel efficiency, throttle response, and emissions control.
- Controls camshaft timing: Actuates oil flow to the VVT sprocket to vary valve timing across engine loads and speeds.
- OE-replacement calibration: Engineered to match original electrical response, oil-flow rate, and pressure regulation for precise control.
- Direct-fit design: Installs using factory connectors and mounting points — no modification required.
- Connector details: One black D-shaped female connector with two male pin terminals, three mounting holes, a 70 mm housing width, and a 4 mm shaft diameter.
