• Q: How to replace the rear Parking Assist Distance Sensor on 2002 Buick Park Avenue?

  A: Begin the replacement of the rear object sensor by taking off the rear bumper fascia while disconnecting its electrical connector to the sensor. Unlock the housing tabs using a finger then pull out the rear object sensor. Pushing the spring releases the sensor from its housing and causing the housing tabs to open for removal. The bezel can be extracted from the fascia by pushing it through the opening. The installation procedure requires painting the new rear object sensor such that the paint thickness stays below 6 mils while using a suitable non-ferrous metals paint thickness gauge. Press the ring until the bezel reaches fascia level to attach the rear object sensor bezel while the keyhole should align with the key to insert the sensor bezel into the fascia. Put the housing onto the bezel while handling it from behind the rear fascia until both spring keys on the housing top and bottom provide full locking. The first installation step should begin with spring attachment to housing then sensor connection of the decoupling ring. When inserting the sensor into the housing position its connector toward the passenger side while allowing the sensor tabs to support the housing cutouts. Connect the electrical connector to the rear object sensor while replacing the rear bumper fascia in its proper position.
