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.
