Where is the ABS wheel speed sensor located?
In the image below a stator ring or as it is sometimes called a reluctor can be located inside the bearing hub, rear axle housing, or on the CV joint itself. Slowly rotate the ring to check it for damage or missing teeth. Wheel sensors are magnetic so check for metal shavings around the sensor which can hinder performance.
Where is the speed sensor on a car?
Locate the electrical connector from a particular the wheel speed sensor which is near the frame in the wheel well in most cases. Don’t be confused by other wiring harnesses that may lead down to the wheel such as the brake pad wear sensor.
How can I tell if my ABS sensor has failed?
To determine if a sensor has failed there are one of two methods that can be used. Connect a code tool to pin point the sensor, or check them manually. These sensors are subject to road conditions and vibrations which can cause them to short out and stop working.
What causes a car sensor to stop working?
Connect a code tool to pin point the sensor, or check them manually. These sensors are subject to road conditions and vibrations which can cause them to short out and stop working. Follow the guide below to perform a sensor test using a voltmeter. Watch the video below to get an idea for what you are in for when testing the sensor.

When to replace a bad wheel speed sensor?
1. ABS Light is illuminated on the dashboard Since the wheel speed sensor also monitors the anti-lock braking system on your car, it’s common for the ABS Light to illuminate when the sensor is worn out, disconnected, or has been struck by debris, which means you’ll have to replace the wheel speed sensor.
Is the wheel speed sensor the same as the transmission?
The wheel speed sensor is different than the speed sensor attached inside the vehicle’s transmission. Its job is to record the actual wheel speed and report this data to the vehicle ECU which controls all electronic functions on the car, truck, or SUV.
Which is more accurate, a WSS or a wheel speed sensor?
This type of sensor can generate a more accurate wheel speed signal at low speeds (down to 1 mph) than a magnetic WSS. It can also tell if the wheel is rotating forwards of backwards. With this type of sensor, the body control module or ABS module provides a reference voltage to power the sensor.
