Yes, it is possible to clean the Dorman - OE Solutions 970-012 ABS Wheel Speed Sensor or similar AVS Wheel Speed Sensors, and doing so can sometimes restore its proper function if dirt or debris is causing issues. Here’s how you can clean the ABS wheel speed sensor:
Tools and Materials Needed:- Jack and jack stands or a car lift
- Lug wrench
- Screwdriver or socket set (to remove the wheel and access the sensor)
- Clean, lint-free cloth or a soft brush
- Brake cleaner or a suitable electrical contact cleaner
- Safety gloves and glasses
-
Safely Lift the Vehicle:
- Park the vehicle on a flat surface, engage the parking brake, and lift the vehicle using a jack. Secure it with jack stands or use a car lift if available.
-
Remove the Wheel:
- Use a lug wrench to remove the lug nuts and take off the wheel to access the ABS sensor.
-
Locate the ABS Sensor:
- The ABS sensor is usually located near the brake rotor, attached to the wheel hub. It may be held in place by a bolt or clip.
-
Inspect the Sensor and Area:
- Check the sensor and the surrounding area for dirt, grime, or metal shavings that could be interfering with its operation.
-
Clean the Sensor:
- Spray the sensor with brake cleaner or electrical contact cleaner. Avoid using harsh chemicals or high-pressure air, as these can damage the sensor.
- Gently wipe the sensor with a clean, lint-free cloth. If needed, use a soft brush to remove stubborn debris, but be careful not to damage the sensor.
-
Check the Tone Ring:
- While you’re cleaning, inspect the tone ring (the toothed ring that the sensor reads) for any debris or damage. Clean it if necessary.
-
Reassemble the Components:
- Once the sensor and tone ring are clean, reattach any bolts or clips that were removed, and ensure the sensor is securely in place.
-
Reinstall the Wheel:
- Put the wheel back on, tighten the lug nuts, and lower the vehicle.
-
Test the Vehicle:
- After cleaning, take the vehicle for a test drive to ensure the ABS light is off and the system is functioning correctly.
- Handle with Care: The ABS sensor is a sensitive electronic component, so handle it carefully during cleaning.
- Check for Damage: If the sensor appears damaged or the cleaning doesn’t resolve the issue, it may need to be replaced.
- Use Proper Cleaners: Only use brake cleaner or an appropriate electrical contact cleaner that evaporates quickly and leaves no residue.
Cleaning the ABS wheel speed sensor can often resolve issues related to dirt and debris, but if the problem persists, further diagnostics or sensor replacement may be necessary.
