DTC
B1411/11 Room Temperature Sensor Circuit
DESCRIPTION
The room temperature sensor is installed in the instrument panel. It detects the cabin temperature to control the
air conditioning AUTO mode. The resistance of the room temperature sensor changes in accordance with the
cabin temperature. As the temperature decreases, the resistance increases. As the temperature increases, the
resistance decreases.
The A/C amplifier applies voltage (5 V) to the room temperature sensor and reads voltage changes as the
resistance of the room temperature sensor changes. This sensor also sends appropriate signals to the A/C
amplifier. The room temperature sensor is integrated with the room humidity sensor.
DTC No.
