About this ABS Wheel Speed Sensor

The GENUINE BMW 34-52-1-178-981 ABS wheel speed sensor measures how fast its wheel is turning. The ABS, traction control and stability systems depend on its signal, so a failed sensor usually turns on several warning lights.

Frequently asked questions

What does an ABS sensor do?

It reads a toothed or magnetic ring at the wheel hub and sends the wheel's speed to the ABS control unit, which uses it to prevent wheel lock-up and control traction and stability.

What are the signs of a failed ABS sensor?

ABS, traction control or stability warning lights, fault codes for one wheel, and on some cars an incorrect speedometer reading or disabled cruise control.

How do I know which sensor I need?

Sensors are usually specific to front or rear and sometimes left or right. The fault code or a scan tool reading identifies which wheel; check the position in the product details.

Can I replace an ABS sensor myself?

Usually, yes. Clean the sensor bore before installing the new sensor, route the cable away from moving and hot parts, and clear the fault codes afterwards. Also check the tone ring for damage or rust.

How do I make sure this ABS wheel speed sensor fits my car?

Compare the part numbers listed on this page with the number on your old part or in your vehicle's parts catalog, and check the fitment information. If you are unsure, contact us with your VIN before ordering.
