INSPECTION



See Figure 1

  1. Remove the sensor from the rear axle. Inspect the sensor for physical damage, such as cracks or missing pieces. If any such damage is evident, replace the sensor with a new one.
  2.  
  3. Using a Digital Volt-Ohmmeter (DVOM), set to the ohmmeter function, measure the resistance between the sensor terminals, which should be 1.2-1.6 kilohms at 68°F (20°C). If the resistance is not as specified, replace the sensor with a new one.

  1. Measure the resistance between each sensor terminal and the sensor metal body, which should be 1 megohm or more. If the resistance is not as specified, replace the sensor with a new one.
  2.  
  3. Install the sensor in the rear axle.

Fig. Fig. 2: The rear wheel speed sensors are mounted at either end of the rear axle assembly-during installation, ensure that the sensor mounting tab is not bent, otherwise replace the sensor

  1. Block the front wheels, then raise and safely support the rear of the vehicle on jackstands.
  2.  
  3. Detach the wiring harness connector from the sensor.
  4.  
  5. Remove the wheel speed sensor retaining bolt, then pull the sensor out of the axle.
  6.  

To install:
  1. Inspect the sensor and rotor for damage, especially that the sensor and rotor teeth are free of metal particles.
  2.  
  3. Install the sensor into the rear axle, then install and tighten the retaining bolt to 186 inch lbs. (21 Nm).
  4.  
  5. Reattach the wiring harness connector to the sensor.
  6.  
  7. Lower the vehicle, and connect the negative battery cable.
