How to clean wheel ABS sensor

One of the most annoying things to happen when you own a car, is to have ABS light come on telling you that something is not right.

Although this is concerning because your ABS will no longer work, there are many things you can check yourself.

Checking and cleaning your wheel ABS sensor is one of those things. Sometimes it can be serious, but most of the time it just needs to be cleaned.

What you need

You just need a few tools and you can clean your sensor and be back on the road. 


Now that you have the few tools you will need; you are ready to start.

Follow these steps to get your ABS sensor clean. Before you start, you need to look in the owner’s manual to see which tires have the ABS sensor. It is often the front tire or both front tires or all four tires may have them. 

  1. Make sure you are parked on a flat surface. Now you can use the wrench to loosen the lug nuts on your wheel. park vehicle to clean the abs sensor
  2. Once the lug nuts are loose, you can jack up your car. For safety, you should use jack stands. Now you can remove the lug nuts.
  3. Once you have removed the lugs nuts, you can remove the wheel. Be sure to keep the lug nuts in a safe place since you will need them to reattach the wheel later on. remove wheel to access abs sensor
  4. Now locate the ABS sensor and remove it. The eaiset way to locate the ABS sensor is to track the electrical wire (not brake line) that goes to the wheel hub. To remove it you will need to remove the bolt. Typically a 10mm bolt but in some cases, this may require Allen key or torx bit.  abs sensor location

  9. Then you replace all the bolts and the rest of the wheel and lug nuts. 
  10. Lower the car and remove the jack stand.

Once you have cleaned the sensors, it is important to realize that the light may still be lit up on the dashboard. You may need to take the car for a test drive as this will often rest the ABS light. 

If the ABS light doesn't reset, use an ABS scanner to read the fault codes and determine the cause of the problem. 

Just a few tools and some time, and you can clean and check your wheel ABS sensors yourself. A little routine maintenance can go a long way towards keeping your car running in excellent shape. 

Cleaning the ABS sensor does not always fix the problem and in some cases, the sensor may need to be replaced.
