• Q: How to replace the rear Parking Assist Distance Sensor on 2007 Buick Terraza?

  A: The first step for replacing the rear object sensor involves removing the rear bumper fascia. The locking tabs found on the housing should first be lifted to expose the rear object sensor. The spring requires compressing to detach from the housing while removing retaining tabs from the housing allows sensor extraction. You should detach the rear object sensor bezel that covers the rear fascia below. The installation process requires avoiding any refinishes on pre-painted sensors. Before installation of the new rear object sensor apply paint but check non-ferrous metal paint thickness no more than 6 mm using an appropriate paint gauge. Position the keyhole properly then use the key to place the rear object sensor bezel flush to the fascia. Insert the housing through cutouts on the bezel starting from the back of the fascia while keeping spring keys at the top and bottom positions. Install the housing spring before fitting the sensor decoupling ring to the housing assembly. The sensor should enter the housing so its connector points toward the passenger side while pressing sensor-tab components into housing cutouts. Proceed with attaching the electrical connector before reinstalling the rear bumper fascia.
