This wheel sensor is an electronic component that monitors wheel speed, providing critical data to the vehicle's ABS, traction control, and other electronic systems. Manufactured to precise specifications, it ensures accurate signal transmission, unlike a worn or damaged sensor which can provide erratic readings. Operators may notice ABS warning lights, reduced braking performance, or issues with traction control when this sensor malfunctions.

Installation & Application Notes

Torque all suspension fasteners to specification — under-torque causes wear, over-torque causes fatigue cracking. Replace bushings in pairs. Grease all zerks after fitting. Check alignment after suspension work.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

The most immediate symptom of a failing wheel sensor is the illumination of the ABS warning light on the dashboard. This can lead to a loss of ABS functionality, potentially increasing stopping distances. If the sensor fails completely, other systems like traction control may also become inoperative, compromising vehicle safety.

Installation Tip

Ensure the mounting surface on the wheel hub is clean and free of rust or debris before installing the new sensor. Avoid using excessive force when tightening the mounting bolt, as this can damage the sensor housing.

Service Note

When replacing a wheel sensor, inspect the corresponding ABS ring for damage or debris and check the wiring harness for any signs of abrasion or corrosion.
