21247147 — Wheel Speed Sensor 20528660 21247147 For Volvo Fh12 Fh16 Fm9 Fm12 Trucks

This wheel speed sensor accurately measures the rotational speed of a wheel, sending this data to the ABS and traction control modules for optimal system function. It is manufactured to meet rigorous OEM quality standards, providing reliable and consistent readings unlike a worn sensor which may produce intermittent or inaccurate signals. Operators may observe illuminated ABS or traction control warning lights, or experience reduced braking performance and stability control issues when this sensor fails.

Installation & Application Notes

Disconnect main battery before working on electrical components. Use dielectric grease on all connector pins. Check ground connections — most electrical faults trace to poor grounds. Test with multimeter before installing new parts.

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 common indication of a failing wheel speed sensor is the illumination of the ABS or traction control warning light on the dashboard. This can lead to a loss of anti-lock braking functionality and reduced stability control, especially during adverse driving conditions. Continued operation without addressing the issue can compromise vehicle safety and potentially lead to uneven brake wear.

Installation Tip

Carefully clean the mounting surface and the tone ring for debris before installing the new sensor to ensure accurate readings. Avoid using excessive force when seating the sensor, as this can damage the sensor or the mounting point.

Service Note

When replacing a wheel speed sensor, inspect the brake pads, rotors, and the tone ring for wear or damage, and check the wiring harness for any signs of abrasion or corrosion.
