• Q: How to replace the rear Parking Assist Distance Sensor on 2001 Buick Park Avenue?

  A: The first task for changing a rear object sensor requires removal of the rear bumper fascia followed by unplugging its electrical connector. The first step requires lifting the locking tabs on the housing before taking out the rear object sensor. Remove the rear object sensor housing by squeezing its spring then pulling it out from the housing . After releasing the tabs on the housing detach it. Press the bezel through the fascia to remove it. Application of the new rear object sensor requires basecoat and clearcoat paint from Paints and Coatings according to Basecoat/Clearcoat Paint Systems but the paint must remain under 6 mils when measured through a metal-compatible paint thickness gauge. To install the rear object sensor bezel you must press the ring inside until the edge matches the fascia. Then align the keyhole to its placement key and push the sensor bezel into the fascia. Apply the housing onto the bezel through the fascia's rear side to allow snapshots between its bezel cutouts while positioning spring keys at its top and bottom. First position the spring within the housing structure before adding the decoupling ring which belongs to the sensor. Install the sensor directly into the housing while positioning its connector towards the passenger side of the fascia yet allowing the sensor tabs to enter the housing cuts. To finish the process connect the electrical cables before reinstating the rear bumper fascia.
