Installation Notes and Tips

Verify connector shape, terminal count, and mounting style against the original sensor before installation. Clean the mounting area and inspect the harness connector for corrosion, damaged terminals, or oil intrusion before connecting the new sensor. Confirm the sensor is seated correctly in the mounting location and that the bracket aligns with the original position on the vehicle.
