DTC B1411/11 Room Temperature Sensor CircuitDESCRIPTION
DTC Detection Condition:
The room temperature sensor is installed in the instrument panel to detect the room temperature and control the heater and air conditioner "AUTO" mode. The resistance of the room temperature sensor changes in accordance with the room 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 the appropriate signals to the A/C amplifier. The room temperature sensor is integrated with the room humidity sensor.
