![]() The wheel speed sensor is mounted really close to the braking system which makes it vulnerable to damage due to high heat caused by the brakes. If there is problem with the wheel speed sensor, whether is covered is grime from regular driving or damaged in some way, the ABS will not get any data from it to control the movement of the wheels. This allows the wheels to resume their movement. ![]() They transmit that data to the ABS which, upon receiving it from one or more wheels, determines that one or more wheels are moving slower as compared to the others and it releases the pressure of the brake fluid. ![]() The wheel speed sensors decide the rate at which the wheels of your vehicle are moving. The Anti-lock Braking System depends on the data from the wheel speed sensor. Wheel speed sensors are located inside the center of the wheel and in some cases, inside the transmission. One of the various reasons for the ABS light to illuminate and stay on is a faulty wheel speed sensor. Common Causes When an ABS Light Comes On #1 – Faulty Wheel Speed Sensor If you see the ABS light come on, the best course of action is to resolve the issue as soon as possible. But a vehicle’s ABS is also prone to wear and tear and can fail. This will allow the car wheels to avoid getting locked up and skidding uncontrollably. This operation may sound simple at first but its importance lies in the controlled stoppage or slowdown of the vehicle while greatly reducing the chances of losing control of the car. The system is capable of this because it is fully automated. The ABS is a safety system which has the ability to recognize a stop in the rotation of the wheels during braking while the car is still in motion, and release the brake fluid pressure which allows the wheels to start rotating again. The main role of the anti-lock braking system is to keep you safe from the any accidents and to make sure that you do not lose control of your car (like skidding) in case of any emergency braking.
