2019 Chevrolet Express 2500 Parking Assist Sensor

Mud, snow, ice or other material on the sensor can interfere with detection. Ford advises keeping the sensors clean and avoiding sharp cleaning tools; inspect the bumper area before assuming a sensor has failed.

Three pins describe the number of electrical contacts, not the complete fit. Sensor shape, connector and the vehicle's parking system must also match. A three-pin sensor is not automatically interchangeable with every other three-pin sensor.

The package must be checked individually. One A-Premium four-sensor set specifies that the wiring harness is not included; the sensor count alone does not describe the rest of the package.

Parking assistance and blind-spot monitoring serve different detection zones and driving situations. Systems can use different sensors or combine technologies, so select the part specified for the vehicle's affected system rather than treating the names as interchangeable.

Paint and surface coatings can affect some sensors. Follow the vehicle and product instructions for the specific sensor and finish; Ford notes that repainting around sensors can impair certain systems.
