Where are the ABS speed sensors located?

A wheel speed sensor, also called an “ABS sensor,” is part of the Anti-lock Brake System (ABS). It is located on the tires (near the brake rotors for the front tires and in the rear end housing for the rear tires).

Can ABS sensors be cleaned?

With the sensor free, take your rag and wipe the sensor until it’s clean. I prefer not to use any chemicals on the sensor to avoid potential problems.
