Kia Carnival (2007 year). Instruction — part 175

2007 > 2.7L V6 GASOLINE >

DESCRIPTION

1. The ambient temperature sensor is located at the front of the condenser and detects ambient air temperature. It is

a negative type thermistor; resistance will increase with lower temperature, and decrease with higher temperatures.

2. The sensor output will be used for discharge temperature control, temperature regulation door control, blower

motor level control, mix mode control and in-car humidity control.

If the ambient temperature is below -3°C (26.2°F), the A/C compressor will be stopped.
The compressor will be operated by manual operating.

INSPECTION

1. Ignition "OFF"

2. Disconnect ambient temperature sensor.

3. Check the resistance of ambient temperature sensor between terminals 1 and 2 whether it is changed by changing

of the ambient temperature.
Specification

Ambient temperature [°C(°F)]

Resistance between terminals 1and 2 (k

4. If the measured resistance is not specification, substitute with a known-good ambient temperature sensor and

check for proper operation.

5. If the problem is corrected, replace the ambient temperature sensor.

REPLACEMENT

1. Disconnect the negative (-) battery terminal.

2. Remove the front bumper. (Refer to BD group)

3. Remove the ambient temperature sensor (A).

4. Installation is the reverse order of removal.
