How to Remove Speed Sensors on a 1994 Buick

The 1994 Buick has an ABS system used to help stop the brakes from locking up in case of an emergency stop. This system works by using speed sensors on each wheel to help determine how fast the wheels are moving and how to properly actuate the brakes to stop the car safely. When they go out, the ABS stops functioning correctly. In this case, the project vehicle is a 1994 Buick Regal, but the process is similar for other Buick cars as well.

Instructions

1

Lift the car onto a set of jack stands using the jack. Make sure the Buick is solidly on the stands before you remove the jack.

2

Undo the wheel lugs using the tire iron and lift the tire off of the front suspension. Set them to the side.

3

Locate the wheel sensors on the backside of the brake disc rotor. Disconnect the electrical connection to the sensor using your hands. Unbolt the two bolts securing the speed sensor to the suspension using the 3/8-inch ratchet and socket. Remove the sensor from the car.
