DTC B1411/11 Room Temperature Sensor Circuit

DESCRIPTION

DTC Detecting Condition:

The A/C room temperature sensor is installed in the instrument panel to detect the cabin temperature and control the heater and air conditioner "AUTO" function. The resistance of the A/C 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 assembly applies voltage (5 V) to the A/C room temperature sensor and reads voltage changes as the resistance of the A/C room temperature sensor changes. This sensor also sends appropriate signals to the A/C amplifier assembly. The room temperature sensor is integrated with the room humidity sensor.
