2007 KIA CARNIVAL Workshop Manual

3.Disconnect the evaporator sensor connector (A).
4. Loosen 2 screws and then remove the evaporator sensor cover(B).
5. Remove the evaporator sensor.
Take care that evaporator core pins are not bent.
6. Installation is the reverse order of removal.

In-car Sensor

2007 > 2.7L V6 GASOLINE >
COMPONENT LOCATION

2007 > 2.7L V6 GASOLINE >
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.

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.
Specification
Temperature [°C(°F)] Resistance between terminals 2and 4 (kΩ)
0 (32) 97.83 ± 2.61%
15 (59) 47.12 ± 1.45%
25 (77) 30.00 ± 1.20%
35 (95) 19.60 ± 1.44%
50 (122) 10.82 ± 2.26%
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.

Photo Sensor

2007 > 2.7L V6 GASOLINE >
COMPONENT LOCATION

2007 > 2.7L V6 GASOLINE >
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.
