Wheel Speed Sensor
Mack

Wheel speed sensors feed real-time rotational data to the ABS and traction systems, enabling controlled braking and stability in diverse conditions. This sensor measures the wheel’s velocity and passes signals to the ECU; discrepancies can trigger false positives or brake drag if dirty or misaligned. Modern wheel speed sensors use magnetic sensing or Hall effect technologies housed in a rugged enclosure designed to tolerate dust, water, and road salt. Proper installation ensures a precise air gap to the tone ring, clean connectors, and a secure harness that resists vibration. Regular maintenance includes inspecting for damaged wiring, cracked protective covers, and any signs of bearing wear near the hub. A healthy sensor contributes to predictable braking response, reduces tire wear, and supports advanced safety features. When selecting, verify compatibility with your ABS module and wheel-end hardware. Source One Parts Center offers reliable wheel speed sensors for maintenance or replacement.
