NOTE
Clear any Diagnostic Trouble Code (DTC) if applicable.

  1. Inspect the sensor connector connection, check terminal for poor connections, loose wires, bent, broken, or corroded pins, and then verify that the connector is securely fastened.
  2.  
  3. Remove the sensor from the engine.
  4.  
  5. With the sensing portion of the sensor immersed in hot water, check the resistance between terminals 1 and 2 using an ohmmeter at the following temperatures:
    1. Engine coolant temperature 68°F, resistance 2.1-2.9 kohms.
    2.  
    3. Engine coolant temperature 122°F, resistance 0.68-1.00 kohms.
    4.  
    5. Engine coolant temperature 194°F, resistance 0.236-0.260 kohms.
    6.  
    7. If it does not meet specification, replace the sensor.
    8.  

  6.  

  1. Remove the sensor from the engine.
  2.  
  3. With the sensing portion of the sensor immersed in hot water, check the resistance.
  4.  
  5. Specification should be 0.32 kohm at 176 degrees F.
  6.  
  7. Replace the sensor, as required.
  8.  

  1. Be sure the ignition switch is in the OFF position.
  2.  
  3. Disconnect the sensor electrical connector.
  4.  
  5. Using an ohmmeter measure the resistance between terminals 1 and 3 of the sensor connector.
  6.  
  7. Specifications are as follows (error range is 2-3 percent):

    Temperature 32 degrees F, resistance 2.45 kohms
     
    Temperature 68 degrees F, resistance 1.15 kohms
     
    Temperature 176 degrees F, resistance 0.587 kohms
     
    Temperature 212 degrees F, resistance 0.322 kohms
     
    Temperature 230 degrees F, resistance 0.188 kohms
     
    Temperature 248 degrees F, resistance 0.147 kohms
     

  8.  
  9. If within specification, check the PCM as follows, ignition OFF. Connect the scan tool. Turn the ignition ON and engine OFF. Select simulation function on the scan tool. Simulate voltage at terminal 3 of the sensor connector.
  10.  
  11. If the signal voltage value does not change, substitute a known good PCM and repeat the test. Replace the PCM as required. If the signal voltage value does change, check connectors for looseness, poor connection, binding etc. Correct and retest.
  12.  
  13. If the temperature and resistance check is not within specification, check for deterioration and damage to the sensor.
  14.  
  15. Retest, if still not within specification substitute a known good sensor and retest. Replace the sensor, as required.
  16.
