Detailed Description

Walker Products, through its Walker Products line, has a long history in fuel system and engine management components and manufactures parts to meet or exceed OEM standards and specifications. Part number 590-1040 is engineered as a replacement VVT solenoid for Subaru engines that rely on controlled oil flow to adjust cam timing. For buyers searching for a Subaru Baja VVT solenoid, Subaru Impreza VVT solenoid, Subaru Legacy VVT solenoid, Subaru Outback VVT solenoid, or Subaru Forester VVT solenoid, this unit provides a focused fitment match for the listed model years.

This part cross-references Dorman OE Solutions 917-279 and Gates VVS166 for the same application.

What It Helps Address

• Check engine lights related to variable valve timing control
• Rough idle or inconsistent engine response tied to cam timing control
• Delayed or erratic VVT actuation caused by a failing solenoid
• Oil control issues affecting timing advance or retard operation
• Replacement needs for worn electrical connector or solenoid assembly

Installation Notes and Tips

Verify connector style, terminal layout, and mounting-hole configuration before installation. Clean the mounting surface and inspect the engine oil condition, since VVT solenoids depend on proper oil flow and pressure to operate correctly. Confirm the vehicle application against the listed fitment for 2004-2006 Subaru Baja, 2004-2006 Subaru Impreza, 2005-2006 Subaru Legacy, 2005-2006 Subaru Outback, and 2004-2005 Subaru Forester.
