DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
Is 1st trip DTC detected? YES >> Proceed to EC-208, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK INTAKE AIR TEMPERATURE SENSOR POWER SUPPLY

Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK INTAKE AIR TEMPERATURE SENSOR POWER SUPPLY CIRCUIT

Is the inspection result normal? YES >> Perform the trouble diagnosis for power supply circuit.
NO >> Repair or replace error-detected parts.
3.CHECK INTAKE AIR TEMPERATURE SENSOR GROUND CIRCUIT

Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK INTAKE AIR TEMPERATURE SENSOR
Check the intake air temperature sensor. Refer to EC-207, "Component Inspection".
Is the inspection result normal? YES >> GO TO 5.
NO >> Replace mass air flow sensor (with intake air temperature sensor). Refer to EM-24, "Exploded View".
5.CHECK INTERMITTENT INCIDENT
Refer to GI-41, "Intermittent Incident".
>> INSPECTION END
Component Inspection
1.CHECK INTAKE AIR TEMPERATURE SENSOR
