Park Assist Sensor - Installation5 steps
ℹ NOTE
The park assist sensors (3) and the sensor spacers (O-rings) are each available for separate service replacement. The sensor brackets (5) are bonded to and integral to the back side of the rear bumper fascia (2).
ℹ NOTE
Production and all service replacement O-ring spacers are tapered. The wide side (base) of the O-ring should be seated against the sensor housing and the narrow side should be oriented toward the outer surface of the sensor membrane and the rear fascia.
ℹ NOTE
Be certain that each sensor membrane is properly centered in the openings of the rear fascia and that the O-ring spacers are not pinched. Improper centering or pinched O-rings can be detrimental to proper park assist sensor operation.

  1. Engage the O-ring spacer around the circumference of the sensor membrane protrusion.
  2. Align and insert the sensor (3) into the sensor bracket (5) on the back of the rear bumper fascia (2) until the bracket latch features (1) are fully engaged over the top and bottom latch tabs of the sensor. Be certain that the sensor membrane is flush with the outer surface of the fascia.
  3. From the back of the fascia, reconnect the wire harness connector (4) to the sensor connector receptacle.
  4. Reinstall the rear wheel flare and the bumper fascia on the same side of the vehicle as the park assist sensor that was serviced. Rear Bumper Fascia - Installation.
  5. Reconnect the battery negative cable.

  1. Disconnect and isolate the battery negative cable.
  2. Remove the rear wheel flare and loosen the bumper fascia on the same side of the vehicle as the park assist sensor requiring service. Rear Bumper Fascia - Removal.
  3. From the back of the fascia (2), disconnect the wire harness connector (4) from the park assist sensor (3) connector receptacle.
  4. Carefully pry the sensor bracket (5) latch features (1) away from the top and bottom latch tabs of the sensor far enough to disengage the sensor from the bracket.
  5. Disengage the O-ring spacer from around the circumference of the sensor membrane protrusion.

DESCRIPTION Vehicles equipped with the park assist system have four park assist sensors (1) installed on the rear bumper fascia. Only the membrane (3) of each sensor is visible through a hole in the outer vertical surface of the fascia. The remainder of each sensor including the sensor mounting bracket, the sensor spacer and the sensor wiring connection is concealed behind the fascia. A sensor wire harness behind the fascia connects the sensors to the vehicle electrical system. Each of the four sensors is identical in construction and is interchangeable. The electronic circuitry and a communication chip for each sensor is enclosed and protected within the molded black plastic sensor housing. The housing includes an integral connector receptacle (4) and two integral latch tabs (2). The sensor membrane extends from the surface of the sensor housing, and is finished to match or contrast with the outer surface of the fascia. The numbering system for the park assist sensors allows for up to twelve sensors on the vehicle, six front and six rear. The sensors are numbered in a clockwise manner starting at the left front bumper. The left front sensor (if equipped with front park assist) is the number 1 sensor. The numbering continues in a clockwise direction around the vehicle. Since this vehicle uses only four rear sensors, sensor numbers 7 and 12 are omitted, so the left rear sensor is the number 11 sensor. A resilient O-ring spacer around the circumference of each of the four sensor membranes (2) isolates the membrane from the openings in the fascia (1). Each sensor is snapped into its own dedicated molded plastic mounting bracket. Each mounting bracket is heat-staked to the back side of the rear fascia. The park assist sensors cannot be adjusted or repaired. If ineffective or damaged they must be replaced. The sensors and the spacers are each available for individual service replacement.
