In-car Temperature Sensor Test

  1. Remove the humidity/in-car temperature sensor (see HUMIDITY/IN-CAR TEMPERATURE SENSOR REPLACEMENT  ).
  2. Connect the humidity/in-car temperature sensor 4P connector.
  3. Test the humidity/in-car temperature sensor while holding it in front of the dashboard center vent.
    • Measure the resistance with the system set to Max Cool.
    • Measure the resistance with the system set to Max Hot.
  4. Compare the resistance reading between the No. 4 and No. 3 terminals of the humidity/in-car temperature sensor with the specifications shown in the graph; the resistance should be within the specifications.
