Walker 590-1236 Engine Variable Valve Timing (VVT) Solenoid - Exhaust (Right)

Walker VVT Solenoid for OE Cam Timing Control

Walker 590-1236 is an OE replacement engine variable valve timing solenoid for exhaust-side cam timing control. It regulates pressurized oil flow to the cam phaser or VVT sprocket, helping restore proper valve timing response on select Ford and Lincoln applications.

Built for direct-fit service on the exhaust (right) side, this Walker VVT solenoid uses a silver housing, blue female connector, oblong connector shape, and a 2-terminal pin-style electrical interface for factory-style integration.

Key Features

• OE replacement VVT solenoid for dynamic camshaft control
• Controls oil flow to the cam phaser or VVT sprocket
• Silver body with blue connector for factory-style identification
• 1 connector, 2 terminals, female connector gender, male terminal gender
• Oblong connector shape with pin-style terminals
• Exact-fit design for exhaust (right) position service
• Walker part number 590-1236 for catalog and cross-reference lookup

Detailed Description

Walker 590-1236 is engineered to restore variable valve timing operation when the original solenoid is restricted, electrically open, or mechanically stuck. By metering engine oil pressure to the cam phaser, it helps the engine adjust valve timing based on load and speed, which supports smoother throttle response, stable idle quality, and emissions system performance. This part cross-references Dorman OE Solutions 916-724 for the same application. It is a direct replacement for select 2015-2017 Ford Expedition, 2015-2016 Ford F-150, 2015-2017 Lincoln Navigator, and 2016-2020 Ford Transit-150, Transit-250, Transit-350, and Transit-350 HD exhaust right applications.

Common Issues It Can Help Resolve

• Check engine lights related to VVT circuit or cam timing faults
• Rough idle or hesitation during acceleration
• Reduced power from incorrect exhaust cam timing
• Oil control valve sticking from contamination or wear
• Fault codes such as P0010-P0014 or P0020-P0024

Installation Notes

Verify the exhaust (right) position and connector style before installation. Clean engine oil passages and inspect the wiring connector for corrosion or damaged terminals before replacing the solenoid. This part is designed for factory wiring and OE-style mounting on the listed Ford and Lincoln vehicles, including Ford Transit-150, Transit-250, Transit-350, Transit-350 HD, Expedition, F-150, and Lincoln Navigator applications.

Quality Assurance

Walker manufactures this VVT solenoid to meet or exceed OE specifications for electrical response, oil flow control, and pressure regulation. The unit uses heat-resistant housing materials, precision-machined internal valve components, and oil-sealed connectors for long-term engine service.
