Keep camshaft timing responding on command with the Walker Products Engine Variable Valve Timing (VVT) Solenoid 590-1027. This oil-control solenoid regulates the flow of pressurized engine oil to the camshaft phaser, letting the ECM advance or retard valve timing across the rev range. It installs as a direct-fit replacement for a long list of Lexus and Toyota applications, including the 2007-2020 Toyota Tundra, 2007-2017 Lexus LS460, 2008-2020 Toyota Sequoia, 2010-2020 Toyota 4Runner, 2010-2020 Lexus GX460, 2015-2020 Lexus RC F, 2016-2020 Lexus GS F and 2018-2020 Lexus LC500 — see the Buyer's Guide tab for the full list.
- Cam timing control: Directs ECM-commanded engine oil to the camshaft phaser to advance or retard valve timing.
- Direct-fit application: Serves as a direct-fit replacement for the listed Lexus and Toyota applications.
- Position coverage: Cataloged in intake and exhaust, and left and right positions depending on the application.
- Signs it may need replacing: Rough idle, reduced fuel economy, or VVT-related trouble codes — when a failed solenoid is the cause.
When the original solenoid sticks or fails electrically, valve timing can no longer be adjusted on command, which may set VVT-related codes and disturb idle quality. If a failed solenoid is the cause, this unit replaces it and re-enables the ECM's control over cam timing. Diagnose the cause before replacing.
