DTC CONFIRMATION PROCEDURE
1.INSPECTION START
Is it necessary to erase permanent DTC? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK INTAKE AIR TEMPERATURE (IAT) SENSOR
Monitor item | Condition | Value (Approx.) | |
INT/A TEMP SEN | Temperature [°C (°F)] | 25 (77) |
1.9 - 2.1 (V) |
Is the inspection result normal? YES >> GO TO 5.
NO >> Proceed to EC-207, "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 −10°C (14°F) and 35°C (95°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-207, "Diagnosis Procedure".
NO >> INSPECTION END 5.CHECK INTERMITTENT INCIDENT Refer to GI-41, "Intermittent Incident".
>> INSPECTION END
Diagnosis Procedure
1.CHECK INTAKE AIR TEMPERATURE (IAT) SENSOR
Check intake air temperature sensor. Refer toEC-207, "Component Inspection".
Is the inspection result normal? YES >> GO TO 2.
NO >> Replace mass air flow sensor (with intake air temperature sensor). Refer to EM-24, "Exploded View".
2.CHECK INTERMITTENT INCIDENT
Refer to GI-41, "Intermittent Incident".
>> INSPECTION END
Component Inspection
1.CHECK INTAKE AIR TEMPERATURE SENSOR
Monitor item | Condition | Value (Approx.) | |
INT/A TEMP SEN | Temperature [°C (°F)] | 25 (77) | 1.9 - 2.1 (V) |
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace mass air flow sensor (with intake air temperature sensor). Refer to EM-24, "Exploded View".
