Walker 590-1197 Engine Variable Valve Timing (VVT) Solenoid

Walker VVT Solenoid for OE Cam Timing Control

Walker Products VVT Solenoid 590-1197 restores oil-controlled camshaft timing in modern engines that rely on precise variable valve timing. This OE replacement solenoid regulates pressurized oil flow to the cam phaser or VVT sprocket, helping maintain smooth throttle response, fuel efficiency, and emissions performance.

• OE replacement Engine Variable Valve Timing (VVT) solenoid
• Silver housing with black connector color
• 1 female connector, square shape
• 2 male terminals, spade terminal type
• 3 mounting holes for factory-style installation
• Precision internal valve design for oil flow control and pressure regulation
• Heat-resistant plastic housing and oil-sealed connector construction

How This VVT Solenoid Works

The Walker 590-1197 is built to meet or exceed OE electrical response and oil control requirements for dynamic camshaft timing systems. When the engine control system commands a timing change, the solenoid meters oil to the cam phaser so valve timing can adjust to load, speed, and driving conditions. This helps restore factory-level operation on applications such as Chevrolet Camaro, Chevrolet Corvette, Cadillac CTS, and GMC Sierra 1500.

This part cross-references Standard Ignition VVT376 for the same application.

Common Problems It Can Address

• Check engine lights with timing-related fault codes such as P0010-P0014 or P0020-P0024
• Rough idle caused by inconsistent cam timing control
• Hesitation or reduced power during acceleration
• Sticking open or closed due to oil contamination or wear
• Poor fuel economy and increased emissions from incorrect valve timing
