Restore precise valve timing control with the Walker Products Engine Variable Valve Timing (VVT) Solenoid 590-1027, an OE-replacement solenoid that regulates the flow of pressurized oil to the cam phaser or VVT sprocket to adjust valve timing based on real-time driving conditions. It's cataloged as a direct-fit replacement across a wide Toyota and Lexus range, including the 2010-2020 Toyota 4Runner, 2008-2020 Sequoia, 2007-2020 Tundra, 2008-2017 Lexus IS350 and 2007-2017 Lexus LS460 — see the "Vehicles it fits" section for the full list of applications. Depending on the application it is cataloged in intake and exhaust as well as left and right positions.
- OE-Replacement Calibration: Built to OE-level electrical specs, oil-flow rate, and response timing for precise engine control.
- Built for Harsh Environments: Heat-resistant plastic housing, precision-machined internal valve, and oil-sealed connector for long-term operation.
- Controls Camshaft Timing: Actuates oil flow to the VVT sprocket to optimize valve timing for power, fuel economy, and emissions.
- Exact OE Fit: Installs using factory connectors and mounting points with no modification required.
Over time a solenoid can clog, stick open or closed, or fail electrically — triggering fault codes (e.g. P0010-P0014, P0020-P0024), rough idle, hesitation, or reduced power. If a failed VVT solenoid is the cause, this unit replaces it.

Frequently Asked Questions
What does this VVT solenoid do?
It regulates the flow of pressurized oil to the cam phaser or VVT sprocket, adjusting valve timing based on real-time driving conditions to support power, fuel economy, and emissions.
What are the signs my VVT solenoid may need replacing?
A solenoid that clogs, sticks open or closed, or fails electrically can trigger fault codes such as P0010-P0014 or P0020-P0024, along with rough idle, hesitation, or reduced power. Diagnose the cause before replacing.
Will this fit my vehicle?
It's cataloged as a direct-fit replacement for many Toyota and Lexus models, including the 2010-2020 4Runner, 2007-2020 Tundra, and 2008-2017 Lexus IS350. Check the "Vehicles it fits" section to confirm your application.
Does it require modification to install?
No. It's designed to install using the factory connectors and mounting points with no modification required.
What position does this solenoid fit?
