Room Temperature Sensor Circuit; 2016 MY Tacoma [08/2015 - ]
DTC B1411/11 Room Temperature Sensor Circuit
DESCRIPTION
The cooler thermistor (room temperature sensor) is installed in the instrument panel to detect the cabin
temperature which is used to control the air conditioning system AUTO mode. The resistance of the cooler
thermistor (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 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).
