Walker 590-1402 Engine Variable Valve Timing (VVT) Solenoid

Walker VVT Solenoid for OE Cam Timing Control

Walker 590-1402 is an OE replacement engine variable valve timing solenoid for modern GM applications that use variable cam timing. It regulates pressurized oil flow to the cam phaser or VVT sprocket so the engine can adjust valve timing based on load and speed.

Compatible With 2019-2021 Chevrolet Silverado 1500, 2019-2021 GMC Sierra 1500, and 2020-2021 Cadillac CT4 with variable cam timing.

Key Features

• OE-style VVT solenoid for dynamic camshaft control
• Heat-resistant plastic housing for engine-bay durability
• Precision-machined internal valve for oil flow regulation
• Oil-sealed connector design for long-term electrical reliability
• Exact-fit design for factory wiring and mounting points
• Black connector with oblong shape, blade terminals, and female connector type
• Two mounting holes, two terminals, and included seal

Detailed Description

The Walker Products 590-1402 VVT solenoid is built to restore factory cam timing response on vehicles equipped with variable cam timing. By controlling oil pressure to the cam phaser, this solenoid helps the engine adjust valve opening events for smoother operation, improved throttle response, and better combustion efficiency. It is engineered to meet or exceed OE specifications for electrical response, oil flow control, and pressure regulation, making it a direct replacement for a failed or restricted original unit.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Walker 590-1402 is a practical replacement choice for Silverado 1500, Sierra 1500, and Cadillac CT4 owners addressing timing-related drivability concerns. The part number 590-1402 is also useful when searching for an OE replacement VVT solenoid with the correct connector style and mounting layout.

What It Helps Resolve

• Check engine codes such as P0010-P0014 or P0020-P0024
• Rough idle related to variable cam timing control
• Hesitation or reduced power during acceleration
• Sticking open or closed VVT solenoid operation
• Oil flow control issues affecting cam phaser response

Installation Notes and Tips

Verify connector shape, terminal count, mounting hole layout, and seal condition before installation. Clean the mounting area and inspect the engine oil condition, since contaminated oil can contribute to VVT solenoid restriction and repeat failure. Use factory wiring and hardware locations for an OE-style installation.

Quality Assurance

Walker designs this VVT solenoid to meet or exceed OE specifications for electrical response, oil flow control, and pressure regulation. The 590-1402 uses a heat-resistant housing, precision internal valve components, and an oil-sealed connector to support reliable operation in continuous engine service.
