What Causes Wheel Speed Sensor Failure? Since many wheel speed sensors are built into the bearing hub, if the bearing fails, the sensor will typically fail along with it due to noise and vibration. Like other parts of your braking system, your ABS sensors can also wear out over time and simply stop working.

If your ABS sensor is bad, you'll need to replace it. This is because a bad ABS sensor can cause your ABS system to fail when you need it most. Replacing an ABS sensor is not a difficult task, but it's one that should be left to a professional. They'll have the tools and knowledge necessary to do the job right.

The average cost to replace your ABS Speed Sensor is $200 - $400. Pricing may vary based on the type of car you have, as well as the type of (and quality) auto shop that you go to.
