How to Remove an Anti-Lock Brake Sensor

Removing an ABS sensor is a fairly simple procedure. The sensors are located at each wheel hub or at the rear two wheel hubs (for two wheel ABS set-up). Check the service manual for any specific cautions for removing the sensor.

Difficulty: Moderately Easy

Instructions

Things You'll Need:

• Screw driver
• Wire cutters
• Open end box end wrench

ABS removal procedure

1. Use wire cutters to cut the sensor lead just above the sensor. This will keep from accidentally shorting the sensor wire and causing damage to the control module.

2. The speed sensor is located in its own housing which is usually attached near the wheel hub by a screw. Use a screw driver to unscrew the ABS housing. For mounts with a set screw for adjusting the air gap in the sensor, unscrew the set screw and remove.

3. The sensor housing is mounted with a lock ring. Use the appropriate open end box end wrench to loosen and remove the lock ring. The sensor can now be removed with the housing.

Tips & Warnings

• Do not use magnetized or magnetic tools when diagnosing the sensor wire or adjusting the sensor air gap. Magnetic sources will damage the ABS control module.
• Safety glasses should be worn throughout the procedure to avoid eye injury.
