DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Is it necessary to erase permanent DTC? YES >> GO TO 3.
NO >> GO TO 2.
2.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-193, "Component Function Check".
NOTE:
Use the component function check to check the overall function of the IAT sensor circuit. During this check, a 1st trip DTC might not be confirmed.
Is the inspection result normal? YES >> INSPECTION END
NO >> Proceed to EC-193, "Diagnosis Procedure".
3.PRECONDITIONING
If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following procedure before conducting the next test.
TESTING CONDITION:
>> GO TO 4.
4.PERFORM DTC CONFIRMATION PROCEDURE
NOTE:
Cool the vehicle in an environment of ambient air temperature between −10В°C (14В°F) and 35В°C (95В°F).
CAUTION:
Never turn ignition switch ON during this procedure.
NOTE:
The vehicle must be cooled with the food open.
CAUTION:
Never turn ignition switch OFF during idling.
Is 1st trip DTC detected? YES >> Proceed to EC-193, "Diagnosis Procedure".
NO >> INSPECTION END
Component Function Check
1.CHECK INTAKE AIR TEMPERATURE (IAT) SENSOR
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Proceed to EC-193, "Diagnosis Procedure".
Diagnosis Procedure
1.CHECK INTAKE AIR TEMPERATURE (IAT) SENSOR
Check intake air temperature sensor. Refer toEC-193, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace mass air flow sensor (with intake air temperature sensor). Refer to EM-25, "Exploded View".
Component Inspection
1.CHECK INTAKE AIR TEMPERATURE SENSOR
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace mass air flow sensor (with intake air temperature sensor). Refer to EM-25, "Exploded View".
