Troubleshoot An Abs Sensor Light

The ABS sensor light in your vehicle comes on when the ABS, or anti-lock braking, malfunctions. Most ABS systems do not fail outright, but they can malfunction over time. Replacing the sensors can be an expensive and labor-intensive job. However, replacement sensors are normally available from most auto parts stores. But, before you replace the ABS sensors, you should troubleshoot the ABS sensor light.


1. Open the fuse panel by pulling down on the fuse panel cover in the driver’s side footwell.

2. Locate the fuse for the ABS sensor using the fuse diagram on the underside of the fuse panel cover.

3. Pull the fuse for the ABS using the fuse pullers in the fuse box.

4. Check the fuse for the ABS. If the fuse is broken or damaged in some way, then replace it with a new fuse of the same amperage. The ABS light could come on if there is a short in the system and it blows the fuse.

5. Turn the ignition to the “On” position but do not crank the engine. If the ABS light comes on, crank the engine. If it stays on for more than five seconds, there is a failure in the ABS system, and it needs to be serviced by a professional mechanic.
