How to Reset the Sensor for an ABS on a Pontiac Grand Prix

by Daniel Valladares

The only tool required to reset the sensor for the ABS system on a Pontiac Grand Prix is a socket wrench. Because the ABS system sensor uses the electrical system, resetting the electrical system will reset the ABS system. Resetting the electrical system, however, will also erase other settings on the vehicle, such as saved presets on the radio. If you do not wish to lose those settings, you can reset the ABS sensor through the "brake pedal" procedure.

Brake Pedal Procedure

Step 1

Turn off the Grand Prix's engine, but leave the keys in the ignition.

Step 2

Switch the ignition to the "ON" position, but do not turn on the engine.

Step 3

Press and release the brake pedal. Repeat this two more times, and complete the three repetitions in under five seconds. If this does not work, try again. Ensure that you are completely pressing and releasing the pedal.

Step 4

Remove the keys from the ignition.

Electrical System

Step 1

Open the hood and turn off the Grand Prix's engine.

Step 2

Disconnect the battery from the vehicle using a socket wrench. Wait three minutes.

Step 3

Reconnect the battery and turn the engine on to check the ABS light. If it is off, the sensor is reset. Close the hood.
