OE 26360872 The primary function of the wheel speed sensor is to monitor the rotational speed of each of the vehicle’s wheels and transmit the data to the electronic control unit (ECU). This is critical for several vehicle safety and stability systems, including the Anti-lock Braking System (ABS), Electronic Stability Program (ESP) and Traction Control (TCS). With accurate wheel speed information, these systems are able to adjust braking force and power distribution in real time to improve vehicle safety and handling in all road conditions.
