Detailed Description

The Walker Products 590-1111 VVT solenoid is an engine management component that regulates oil flow to the variable valve timing system. When the solenoid responds correctly, the engine can maintain the timing control needed for smooth operation and proper performance in the specified Toyota Matrix applications. This part number 590-1111 is listed for 2003 Toyota Matrix and 2004 Toyota Matrix vehicles up to May 2004, making fitment verification important before ordering.

Walker Products has supplied automotive fuel system and engine sensor components since 1946 and manufactures parts to meet or exceed OEM standards and specifications. The brand’s engineering and product management support help maintain accurate vehicle application data and technical documentation for parts like this VVT solenoid.

This part cross-references Toyota 15330-22020 for the same application.

What It Helps Address

• Erratic valve timing control
• Check engine light related to VVT system faults
• Rough idle caused by timing control issues
• Reduced engine response from a sticking solenoid
• Oil flow control problems in the variable valve timing circuit

Installation Notes and Tips

Confirm the connector style, terminal layout, and mounting point before installation. Verify vehicle build date on 2004 Toyota Matrix models, since this application is listed only through May 2004. Inspect the electrical connector and related wiring for corrosion or damage, and check engine oil condition because VVT operation depends on proper oil flow and pressure.
