Walker 590-1407 Engine Variable Valve Timing (VVT) Solenoid - Intake
Walker 590-1407 VVT Solenoid Overview
Walker 590-1407 is an engine variable valve timing solenoid built as an OE replacement for intake-side cam timing control. It regulates pressurized oil flow to the cam phaser or VVT sprocket, helping the engine adjust valve timing based on load and speed. This part is listed for 2019-2021 Cadillac CT6, 2019-2021 Cadillac XT4, 2020-2021 Cadillac CT4, 2020-2021 Cadillac CT5, 2020-2021 Cadillac XT5, 2020 GMC Acadia, 2020-2021 Chevrolet Blazer, and 2021 Buick Envision applications with intake position coverage.
- OE replacement VVT solenoid for intake cam timing control
- Controls oil flow to the cam phaser or VVT sprocket
- Heat-resistant plastic housing with oil-sealed connector design
- Precision-machined internal valve for electrical response and oil flow regulation
- Black connector, female connector gender, blade terminals, 6 terminals
- 2 mounting holes, oblong connector shape, seal included
- Fits intake-position applications for Cadillac, Chevrolet, GMC, and Buick platforms
Detailed Application and Function
Walker Products 590-1407 is engineered to restore dynamic camshaft control on modern engines that use variable valve timing. By metering oil pressure to the actuator, the solenoid helps the engine change valve opening timing under different driving conditions. That function supports smoother idle quality, stronger throttle response, improved combustion efficiency, and emissions-system operation. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
What This Part Helps Address
- Check engine lights tied to VVT circuit or cam timing faults, including P0010-P0014 and P0020-P0024
- Rough idle or unstable engine operation
- Hesitation during acceleration
- Reduced power from incorrect cam timing control
- Oil control valve sticking open, sticking closed, or failing electrically
Installation Notes and Tips
Verify the intake position and connector style before installation. Walker 590-1407 uses a factory-style female connector with blade terminals and an exact OE fit, so it installs with original wiring and mounting points when the application matches. Inspect the engine oil condition and related passages during service, since contamination can affect VVT solenoid operation. Confirm the vehicle application for 2019-2021 Cadillac CT6, 2019-2021 Cadillac XT4, 2020-2021 Cadillac CT4, 2020-2021 Cadillac CT5, 2020-2021 Cadillac XT5, 2020 GMC Acadia, 2020-2021 Chevrolet Blazer, or 2021 Buick Envision before replacement.
Quality Assurance
Walker Products manufactures this VVT solenoid to meet or exceed OE specifications for electrical response, oil flow control, and pressure regulation. The design uses a heat-resistant housing, precision internal valve components, and an oil-sealed connector to support reliable operation in continuous engine service.
