    It's the cabin temp. sensor for the HVAC.

    From the FSM:
    "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)."

    welcome,
    I think it's for the HVAC system, for climate control or humidity sensor.
