• Begin by loosening the wheel lugs on the front wheel or wheels (depending on where your sensors are).
• Next, jack the front of the car up and rest it securely on your jack stands. Remove the wheel lugs and take the front wheel or wheels off.
• Turn the steering wheel opposite the side youre working on. For example, if youre working on the passenger side, turn the wheel all the way toward the drivers side. This will give you easier access to the ABS parts.

• Locate the ABS wheel sensor. Remove the bolts that attach it to the rest of the suspension.
• Follow the line and wiring harness to see if there are more bolts. Remember not to force it or pull too hard.
• Different vehicles are set up differently, but the idea is the same in most cases. If youve removed all of the bolts and other attachment components, you should be able to pull the sensor away with no effort at all.

• With the sensor free, take your rag or brush and wipe the sensor until its clean.
• Prefer not to use any chemicals on the sensor to avoid potential problems. However, if the sensor is really grungy, use a mild soapy solution and rinse well.
• To finish the job, reinstall the sensor in exactly the same manner as you removed it. Dont be discouraged if your ABS light doesnt turn off right away. It may take up to a few days for the system to reanalyze itself and reset fully.
