Testing



  1. Using an ohmmeter, measure the resistance between terminals. Resistance should be 120-280 kohms.
  2.  
  3. If the resistance is not as specified, replace the sensor.
  4.  

  1. Disconnect the knock sensor connector.
  2.  
  3. Remove the sensor.
  4.  
  5. Using an ohmmeter, check resistance between the terminal and body. Resistance should be 10 kohm or greater.
  6.  
  7. If the result is not as specified, replace the sensor.
  8.  

To install:
