Why did my ABS light come on after changing wheel bearing?

This is due to the difference in signal strength from the wheel speed sensors (WSS) side to side. The problem is usually associated with air gap difference or wiring and/or connector integrity. In many cases, removing the WSS from the other side, if possible, and cleaning the mounting surface may repair the problem.

What causes the ABS and brake light to stay on?

An ABS warning light that comes on and stays on could signal a problem with various components in and related to the anti-lock brakes. For instance, special sensors monitor the speed of the wheels.

The national average is about $350 to fix the wheel bearings at one wheel. As you might imagine, however, luxury brands cost more. Please note: If the wheel bearings need replacing at one wheel, you don't necessary need to replace the bearings at the other wheel on the same axle. It's not like matching a pair of tires.

Where are the ABS sensors?

The ABS wheel speed sensor is located at the wheel, behind the brake rotor, but some are placed directly on the axle. Each vehicle contains a varying amount of ABS wheel speed sensors. If the system contains four ABS wheel speed sensors, there will be one at each wheel behind the rotor.

Can a speed sensor cause ABS light?
