Circuit/System Verification

  1. Turn OFF the ignition.
  2. Inspect the cooling system surge tank for the proper engine coolant level. Refer to Cooling System Leak Testing and Cooling System Draining and Filling (GE-47716) or Cooling System Draining and Filling (2.4L LE5) .
  3. If the ignition has been OFF for 8 hours or greater, the ECT and the IAT should be within 15°C (27°F) of each other and also the ambient temperature. Ignition ON, observe the scan tool Start-up ECT and Start-up IAT Sensor parameters. Compare those sensor parameters to each other and also to the ambient temperature to determine if the ECT sensor is skewed warmer.
  4. Inspect the thermostatically controlled coolant heater, if equipped, for damage or modifications. Test for proper operation of the coolant heater.
  5. Operate the vehicle within the Conditions for Running the DTC to verify the DTC does not reset. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
