• Oil-control related drivability concerns in the VVT system

Installation Notes and Tips

Verify the connector style, mounting-hole layout, and right-side position before installation. Inspect the electrical connector and surrounding harness for corrosion, bent terminals, or oil contamination. Confirm the engine oil is clean and at the correct level, since VVT operation depends on proper oil pressure and flow. Match the part number 590-1012 to the vehicle application before service.
