Common Issues This Part Can Address

Installation Notes and Tips

Confirm the original sensor location and connector style before installation. Inspect the bumper opening, wiring, and related parking aid components for damage or corrosion, since a sensor replacement will not correct unrelated harness or module issues. Verify vehicle fitment by year, make, model, and rear position before ordering.
