Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This sensor uses a female oblong connector with 3 blade terminals and a single mounting hole, so matching the original connector and sensor location is important. Inspect the harness connector for corrosion or damaged terminals before installing the new sensor, and confirm the application by year, make, model, and VIN where noted.
