An assistance feature for accident prevention, the Parking Aid Sensor uses advanced sonar technology to alert you when you maneuver too close to hazards that are poorly visible. Dorman's sensor restores the parking alert system to original performance. The sensor includes a seal to prevent moisture from entering the unit, one of the most common causes of failure. Plus, it comes with matching connectors and fully compatible electronics, making installation simple and convenient. All Dorman products are engineered in the United States and backed by 100 years of automotive aftermarket experience. Our solutions are thoroughly tested and inspected, and if you experience any difficulty installing or using our parts, we have a dedicated technical support team of ASE Blue Seal certified professionals ready to help.
