Where is the ABS sensor located?
2 Answers
ABS sensor is located on the inner side of the car tire, which can be seen when the car is lifted. ABS sensor is an important component of the ABS system, which usually uses sensors to monitor the speed of the car. ABS sensors are divided into: 1. Linear wheel speed sensor; 2. Ring wheel speed sensor; 3. Hall-effect wheel speed sensor. The functions of ABS sensor: 1. It can fully utilize the effectiveness of the brake during driving; 2. It can shorten the braking time and braking distance of the car; 3. It can effectively prevent the car from skidding or the tires from locking up during emergency braking; 4. It can increase the stability and steering control of the car.
I often help friends inspect their cars, and the ABS sensor is generally located near each wheel. The specific position is mostly within the wheel hub assembly or on the backside of the brake disc, close to the brake rotor, as it needs to directly monitor the wheel speed signal. The location varies slightly depending on the vehicle model—sedans usually have it on the wheel speed sensor bracket, while SUVs might position it at the axle end. All are designed to be securely fixed and not easily loosened. I recommend cleaning it regularly, as mud and oil stains can interfere with the signal, causing the ABS light to illuminate or abnormal braking. When checking, it's best to lift the car and remove the wheel for a closer look. Be careful to avoid damage during the process. If the location is unclear, consult the owner's manual or confirm with a professional shop for safety, as it involves the stability of the braking system and driving safety.
