Kia Carnival (2007 year). Instruction — part 172

2007 > 2.7L V6 GASOLINE >

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.

DESCRIPTION

1. The photo sensor (A) is located at the center of defrost nozzle.

2. The photo sensor contains a photovoltaic (sensitive to sunlight) diode. The solar radiation received by its light

receiving portion, generates an electromotive force in proportion to the amount of radiation received which is
transferred to the automatic temperature control module so that the solar radiation compensation will be performed.
