What It Helps Address

• Rough idle related to VVT control issues
• Check engine lights tied to cam timing or solenoid performance
• Reduced fuel economy from improper valve timing

Installation Notes and Tips

Verify the connector style, terminal layout, and exhaust position before installation. This solenoid uses a square female connector, blade terminals, and a single mounting hole with a bracket, so matching the original configuration is important for proper fitment. Inspect the engine oil condition and related passages during service, since contamination can affect VVT operation.
