The Cooler Thermistor (Room Temperature Sensor) is installed in the instrument panel to detect the cabin temperature which is used to control the heater and air conditioning system AUTO mode. The resistance of the Cooler Thermistor (Room Temperature Sensor) Thermistor changes in accordance with the cabin temperature. As the temperature decreases, the resistance increases. As the temperature increases, the resistance decreases.
The Air Conditioning Amplifier Assembly applies a voltage (5 V) to the Cooler Thermistor (Room Temperature Sensor) and reads voltage changes due to changes in the resistance of the Cooler Thermistor (Room Temperature Sensor).
The Diagnostic Trouble Code (DTC) will be set when the Air Conditioning Amplifier Assembly detects an open or short in the Cooler Thermistor (Room Temperature Sensor) circuit.
