Ford ABS Wheel Speed Sensor Replacement DIY

What you will need

• Ford Fusion ABS wheel speed sensor
• Breaker bar
• Floor jack
• Jack stands
• 8mm nut driver or 8mm socket wrench
• Prying tool

The rear ABS sensor has a different part number from the front and therefore is not interchangeable. The left and right ABS sensors are the same and can be switched without any issue. 

Procedure

1. Park the vehicle on a flat-level ground surface.
   
2. Loosen the lug nuts of the front wheel using a breaker bar.
   
3. Jack up the vehicle's front and support it with jack stands.
   
4. Remove the wheel from the vehicle.
5. Locate the wheel speed sensor on the back of the rotor.
   
6. Remove the 8mm bolt on the sensor using an 8mm socket wrench or 8mm nut driver. Spraying penetrating oil can make removal easier. 

    

7. Pull the sensor out from the vehicle.

    

8. Pull out the cable from all the clips and clamps attached to it.

    

    

   
9. Disconnect the connector by pressing the clip and pulling the connector out.

    

   
10. Connect the new wheel speed sensor.

     

11. Attach the cable of the new wheel speed sensor to the clips and clamps. Make sure that the cable is set in its original routing otherwise it may stretch or rub against the wheel.

     

     

    
12. Insert the sensor into the hole in the knuckle.

     

13. Reinstall the 8mm bolt on the sensor and twist it clockwise to tighten.

     

14. Place the wheel back to the vehicle and reinstall the lug nuts. Torque the lug nuts to spec. 
15. Start the vehicle and turn the steering wheel full left and right a couple of times then drive for about five minutes and ensure the ABS and traction control light reset. 

If the tracking control light and ABS remain on after you replace the faulty ABS sensor, you will have to read the fault codes again from the ABS module to find out what other codes are still present.
