Full Answer

To determine which sensor requires replacement, place the vehicle in reverse, and engage the emergency brake. While the vehicle is in reverse, run your fingers across the sensors. The functioning sensors vibrate when triggered; malfunctioning sensors do nothing.

Determine which types of sensors your vehicle uses. Sensors wired directly into the electrical system or that use an antenna to send signals to the control box and siren are among the most common. Also determine whether removing the bumper cover is necessary to replace the sensor. Remove the fittings that house the sensor, and slide it out of the fitting. Be careful not to damage the fillings, since you must reuse them to house the new sensor. If possible, disconnect the sensor from the wiring at the filling sensor. Otherwise, trace the wiring to the control box, and remove it from there.

Remove the old wiring, and place the new wiring in the proper conduit. Connect the sensor. Replace the fittings and the bumper cover if necessary.
