DESCRIPTION

1. In-car air temperature sensor is located at the center facia lower panel.

2. The sensor contains a thermistor which measures the temperature of the inside. The signal decided by the

resistance value which changes in accordance with perceived inside temperature, is delivered to heater control unit
and according to this signal the control unit regulates incar temperature to intended value.

3. It perceives the inside temperature, changes the resistance value, and enters the corresponding voltage into the

automatic temperature control module.

4. It will used for discharge temperature control, sensor failsafe, temperature door control, blower motor level control,

and A/C auto control.

INSPECTION

1. Ignition "ON"

2. Blow air with changing temperature to the in car sensor air inlet. Measure sensor resistance between 2 and 4

terminals.

In car sensor is negative type thermistor that resistance will rise with lower temperature, and reduce with
higher temperature.

REPLACEMENT

1. Disconnect the negative (-) battery terminal.

2. Remove the A/C control pannel. (Refer to BD group).

3. Disconnect the connector of in-car sensor (A).Loosen the mounting 2 screws and then remove the in-car sensor

(B).

4. Installation is the reverse order of removal.
