ABS Wheel Speed Sensor

ABS WHEEL SPEED SESNORS

The ABS Wheel Speed Sensor is a critical component of the Anti-lock Braking System (ABS) in modern vehicles. It continuously monitors the rotational speed of each wheel and provides this information to the ABS control module, which helps prevent wheel lock-up during hard braking. By doing so, the ABS system maintains vehicle control and stability, especially in slippery or emergency braking situations.

What is an ABS Wheel Speed Sensor?

An ABS Wheel Speed Sensor measures the rotational speed of each wheel and sends this data to the ABS control module (ECU). The control module uses this information to monitor the performance of each wheel during braking. If one wheel begins to slow down more quickly than the others (indicating it is close to locking up), the ABS system will adjust the brake pressure to prevent the wheel from locking and causing a skid.

ABS Wheel Speed Sensors are essential for the proper operation of ABS and are also often used in systems like Traction Control and Electronic Stability Control (ESC), which rely on wheel speed data to optimize vehicle stability and prevent wheel slip under various driving conditions.
