REMOVAL & INSTALLATION



  1. Raise and safely support the vehicle. Turn the front wheel outward for easier access to the sensor.

  5. Carefully remove the sensor wire from the mounting brackets.
  6.  
  7. If the sensor is coated with mud, slush, etc., clean the sensor and surrounding area. This will prevent damage to the sensor and tone wheel during removal.
