Detailed Description

The Walker Products 590-1004 VVT solenoid is used in variable valve timing systems that control oil flow to the cam phaser or related timing components. On vehicles such as the Toyota Camry, Toyota Corolla, Toyota RAV4, Toyota Highlander, Scion xB, and Scion tC, proper solenoid operation is important for stable timing control, drivability, and engine response. This part cross-references Dorman OE Solutions 916-940 for the same application.

Walker Products has supplied fuel system and engine management components since 1946 and manufactures to meet or exceed OEM standards and specifications. The brand’s engineering and product support resources help maintain accurate vehicle application coverage for parts like the 590-1004.

What It Helps Fix

• Check engine light related to VVT solenoid performance
• Rough idle or inconsistent engine operation tied to timing control
• Loss of power or sluggish throttle response
• Oil control issues affecting variable valve timing operation
• Timing-related drivability concerns on affected Toyota, Scion, Lexus, and Pontiac models

Installation Notes and Tips

Verify connector style, terminal count, and mounting-hole layout before installation. Confirm vehicle application by year and model, including the 2009 Toyota Camry through 03/2009 note where listed. For best results, inspect the electrical connector and related engine oil condition during service, since VVT operation depends on clean oil flow and a secure electrical connection.
