  1. Remove the ECT sensor.
  2.  
  3. Measure and record the resistance of the ECT sensor at various temperatures, then compare those measurements to the following. The change in resistance should occur smoothly. If there are any sudden changes, the sensor is faulty.

    -4°F: 28680 ohms
     
    14°F: 16180 ohms
     
    32°F: 9420 ohms
     
    50°F: 5670 ohms
     
    68°F: 3520 ohms
     
    86°F: 2238 ohms
     
    104°F: 1459 ohms
     
    122°F: 973 ohms
     
    158°F: 467 ohms
     
    194°F: 241 ohms
     
    230°F: 132 ohms
     
    266°F: 77 ohms
     

  4.  
  5. If the sensor tests outside of these ranges, replace the sensor.
