INSPECTION



See Figures 1 and 2

  1. Remove the sensor from the steering knuckle. 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.

Fig. Fig. 2: Also be sure to inspect the sensor wheel teeth for damage, such as missing teeth or cracks

  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 steering knuckle.
