Walker 590-1139 Engine Variable Valve Timing (VVT) Solenoid

Walker 590-1139 VVT Solenoid Overview

Walker 590-1139 is an OE replacement engine variable valve timing solenoid for Honda applications that need precise camshaft control. It regulates pressurized oil flow to the cam phaser or VVT sprocket to help restore proper valve timing, throttle response, fuel efficiency, and emissions performance.

Compatible with 2005-2006 Honda Accord, 2005-2006 Honda Odyssey, 2007 Honda Accord, 2007 Honda Odyssey, and 2006-2008 Honda Pilot, this Walker VVT solenoid is built for direct-fit service on timing-related drivability repairs.

• Direct-fit replacement for Honda Accord, Honda Odyssey, and Honda Pilot applications

Detailed Description

Walker Products 590-1139 is engineered to meet OE electrical response, oil flow control, and pressure regulation requirements for variable valve timing systems. By controlling oil delivery to the cam phaser, the solenoid helps the engine adjust valve timing based on load and speed, which is critical for smooth operation in modern Honda Accord, Honda Odyssey, and Honda Pilot engines. This part cross-references Dorman OE Solutions 918-078 for the same application.

The 590-1139 VVT solenoid uses factory-style connectors and mounting points for straightforward replacement service. It is a practical choice when the original solenoid is clogged, sticking, or no longer responding correctly to engine commands.

Common Problems This Part Can Address

• Check engine light with VVT-related fault codes such as P0010-P0014 or P0020-P0024
• Rough idle or unstable engine speed
• Hesitation during acceleration
• Reduced power from incorrect cam timing
• Emissions or fuel economy concerns tied to timing control

Installation Notes and Tips

Verify connector shape, terminal layout, and mounting-hole pattern against the original unit before installation. Clean the oil passages and inspect the engine oil condition, since contamination can affect VVT solenoid operation. Confirm the vehicle application by year and model: Fits 2005-2006 Honda Accord, N/A; Fits 2005-2006 Honda Odyssey, N/A; Fits 2007 Honda Accord, N/A; Fits 2007 Honda Odyssey, N/A; Fits 2006-2008 Honda Pilot, N/A.

Quality Assurance

Walker manufactures this VVT solenoid as an OE replacement component with heat-resistant materials, precision-machined internal valving, and sealed electrical connections to support reliable operation in continuous engine service.
