How do you test a wheel speed sensor?
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.
How can I tell if my wheel sensor has failed?
Slowly spin the hub or axle which will produce the voltage, if no readings can be found the sensor has failed and replacement is required. This is a typical reading from a wheel sensor. Configuration of the sensor mounting is different for each manufacturer but follow the same operation.
Where is the whee L sensor on my car?
Locate and remove the connector. Look for the electrical connector from the certain wheel speed sensor that is near the frame in the wheel in most cases. You must not be confused by those other wiring harnesses which could lead down to the whee l like the brake pad wear sensor.
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.
What does a bad wheel sensor do?
Loss of stability and traction control: If it detects a bad wheel speed sensor, the ABS computer will usually disable the stability and traction control systems, as well. On some vehicles, a bad wheel speed sensor may affect other functions as well, such as hill-start assist and roll stability.
One way to check a suspicious wheel speed sensor is to measure its output voltage. One way to do this is to plug a breakout box into the ABS module’s wiring harness and attach the test leads from a digital volt ohm meter (DVOM) to the appropriate pins for the WSS circuit.
How do you replace a wheel speed sensor?
Part 1 of 1: Replacing the wheel speed sensor. Step 1: Prepare your work area. Make sure the vehicle is on a level, safe surface, and you have set the parking brake. Step 2: Loosen the lug nuts. Use a ½ inch drive breaker bar and a lug nut socket set to loosen all the lug nuts before you jack the vehicle up in the air.
Can you drive with a bad ABS sensor?
That is why in general, it is unsafe to drive a vehicle with a broken wheel speed sensor. If the wheel speed sensor becomes damaged or wears out, initially you probably won’t notice much difference in the way your car performs if your ABS light comes on unless you are driving on slippery pavement.
