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.

2007 > 2.7L V6 GASOLINE >
INSPECTION
1.Ignition "ON"
2. Using the scan tool.
3. Check the output voltage of AQS between terminals 2 and 3.
Specification
Condition Output signal Fresh/recirculation
Normal condition 4 ~ 5VFresh
Hazardous gas detection 0 ~ 1VRecirculation
4.AQS diagnosis and fail safe
Detect the open of signal for 7 seconds without choosing the AQS switch when IG on.
If 2.5V or more is detected for 3.5 seconds or more among 7 seconds, be judged the open of AQS signal.
Operate as below fail safe function, while choosing AQS.
Fail safe: Release the AQS (AQS cannot be selected), Fresh/recirculation maintains previous situation of AQS
selection.
When IG is turned ON, AQS heats for 34±5 seconds, it will output below 1.0 voltage during this time.
REPLACEMENT
1.Disconnect the negative ( - ) battery terminal.
2. Remove the front bumper (Refer to BD group).
3. Remove the AQS (A) after loosening the mounting screws (B).
4.Installation is the reverse order of removal.

INSPECTION
1.Ignition "ON"
2. Using the scan tool.
3. Check the frequency of humidity sensor between terminals 2 and 3.
Humidity (%) Frequency between terminals 2and 3 (Hz)
30 6976 ± 5%
50 6728 ± 5%
60 6600 ± 5%
70 6468 ± 5%
80 6330 ± 5%
90 6186 ± 5%
4. If the measured resistance is not specification, substitute with a known- good humidity sensor and check for proper
operation.
5. If the problem is corrected, replace the Humidity sensor.
REPLACEMENT
1.Disconnect the negative ( - ) battery terminal.
2. Remove the center facia lower panel (A). (Refer to BD group)
3. Disconnect the humidity sensor connector (A).
4. Loosen 2 screws and then remove the humidity sensor (B).
5.Installation is the reverse order of removal.

14.Remove the evaporator core(A).
15.Be careful that the inlet and outlet pipe are not bent during heater core removal, and pull out the heater core.
16. Install the heater core in the reverse order of removal.
17. Installation is the reverse order of removal, and note these items :
a. If you're installing a new evaporator, add refrigerant oil (ND - OIL8).
b. Replace the O - rings with new ones at each fitting, and apply a thin coat of refrigerant oil before installing
them. Be sure to use the right O - rings for R- 134a to avoid leakage.
c. Immediately after using the oil, replace the cap on the container, and seal it to avoid moisture absorption.
d. Do not spill the refrigerant oil on the vehicle ; it may damage the paint ; if the refrigerant oil contacts the paint,
wash it off immediately
e. Apply sealant to the grommets.
f. Make sure that there is no air leakage.
g. Charge the system and test its performance.
h. Do not interchange the inlet and outlet heater hoses and install the hose clamps securely.
i. Refill the cooling system with engine coolant.
