sensor KIA CARNIVAL 2007 Workshop Manual

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.

INSPECTION
1.Ignition "ON"
2. Using the scan tool.
3. Emit intensive light toward photo sensor using a lamp, and check the output voltage change.
4. The voltage will rise with higher intensive light and reduce with lower intensive light.
REPLACEMENT
1.Disconnect the negative ( - ) battery terminal.
2. With the ( - ) driver, remove the photo sensor (B) from the center of defrost nozzle (A).
3.Install in the reverse order of removal.

Water Temperature Sensor

2007 > 2.7L V6 GASOLINE >
DESCRIPTION
1.Water temperature sensor is located at the heater unit.
2. It detects coolant temperature. Its signal is used for cold engine lockout control. When the driver operates the
heater before the engine is warmed up, the signal from sensor causes the heater control unit to reduce blower
motor speed until coolant temperature reaches the threshold value.

INSPECTION
1.Ignition "ON"
2. Using the multi- tester, Measure resistance between terminal "1" and "2" of water temperature sensor.

3. If the measured resistance is not specification, substitute with a known- good water temperature sensor and check
for proper operation.
4. If the problem is corrected, replace the water temperature sensor.
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 grove box. (Refer to BD group)
3. Disconnect the connector (B) of water temperature sensor and then remove the water temperature sensor(A) by
pulling out.

4.Installation is the reverse order of removal.
Take care that wire of water temperature sensor is not to be damaged

Ambient Sensor

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.

2007 > 2.7L V6 GASOLINE >
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 (kΩ)
- 10(14) 164 ± 3%
0 (32) 97.5 ± 3%
10 (50) 59.6 ± 3%
20 (68) 37.5 ± 3%
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.
