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 DTC detected? YES >> Proceed to EC-198, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK ENGINE COOLANT TEMPERATURE SENSOR POWER SUPPLY
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK ENGINE COOLANT 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 ENGINE COOLANT TEMPERATURE SENSOR GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK ENGINE COOLANT TEMPERATURE SENSOR
Check the engine coolant temperature sensor. Refer to EC-199, "Component Inspection (ECT Sensor)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace engine coolant temperature sensor. Refer to CO-24, "Exploded View".
Component Inspection (ECT Sensor)
1.CHECK ENGINE COOLANT TEMPERATURE SENSOR
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace engine coolant temperature sensor. Refer to CO-24, "Exploded View".
