Wheel Speed Sensor
Volvo

Wheel speed sensors provide critical data to the vehicle’s anti-lock braking and traction control systems by measuring the rotational speed of each wheel. For Volvo trucks, these sensors contribute to stable braking under varying loads and road conditions, improving overall vehicle control and safety. The sensors are built to tolerate harsh vibration, temperature swings, and exposure to road debris, while the electrical connector and harness design minimize signal loss. Proper alignment and clean, secure connectors ensure accurate data transmission to the ABS module, preventing spurious fault codes and maintaining optimal braking performance. Regular inspection during maintenance helps prevent intermittent readings that could trigger unnecessary warnings or degrade braking response. Source One Parts Center.
