Step 7. Final confirmation test
Confirm if the problem symptom is troubleshoot and the A/C system is free from any abnormal conditions. If there
existed DTC, clear the DTC. Then , check if the DTC is still detected and if there is any other DTC.
Visual InspectionS7RS0B7224009
Check visually the following parts and systems.

DTC Detecting Condition Trouble Area
Inside air temperature sensor signal voltage is higher than or lower than
specified value for specified time continuously. • Inside air temperature sensor circuit
• Inside air temperature sensor
• HVAC control module
Step
Action YesNo
1 Inside air temperature sensor signal circuit check
1) Disconnect inside air temperature sensor connector.
2) Check for proper connection to inside air temperature
sensor at “PNK/BLK” and “ORN” wire terminals.
3) If OK, measure voltage between “PNK/BLK” wire terminal of inside air temp erature sensor connector and
vehicle body ground with ignition switch turned ON.
Is voltage 4 – 6 V? Go to Step 5.
Go to Step 2.
