Keep camshaft timing responsive with the Walker Products Engine Variable Valve Timing (VVT) Solenoid 590-1402. This OE-replacement solenoid controls the flow of pressurized oil to the cam phaser or VVT sprocket, adjusting valve timing based on real-time engine loads and speeds to support fuel efficiency, throttle response, and emissions control. It drops in as a direct-fit replacement for the 2020-2021 Cadillac CT4, 2019-2021 Chevrolet Silverado 1500, and 2019-2021 GMC Sierra 1500, all equipped with the L4-2.7L engine.
- Controls camshaft timing: actuates oil flow to the VVT sprocket for optimized valve timing.
- Built for harsh environments: oil-resistant seals and a heat-tolerant plastic housing withstand long-term engine operation.
- OE-replacement calibration: engineered to match original electrical specs, oil flow rate, and response timing.
- Connector detail: one black oblong female connector with two blade terminals, plus two mounting holes; a seal is included.
Over time a solenoid can clog, stick, or fail electrically, which may set timing fault codes or cause a rough idle, hesitation, or reduced power. If a failed VVT solenoid is the cause, this unit replaces it. These L4-2.7L applications use two solenoids; sold individually, so order the quantity your engine requires. Country of origin: United States.
Frequently Asked Questions
What does this VVT solenoid do?
