• Ignition on
• Check that the value from the sensor is within its permitted range. Use a thermometer.

  Alternately blow hot and cold air onto the sensor. Check that the value displayed on the sensor changes.

  Shine a light through the grille over the passenger compartment temperature sensor. Check for anything that could obstruct the airflow through the pipe.

  Do not damage the sensor. The sensor is located just inside the grille.

  Remedy as necessary.
