DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.
- Turn ignition switch OFF and wait at least 10 seconds.
- Turn ignition switch ON.
- Turn ignition switch OFF and wait at least 10 seconds.
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
- Turn ignition switch ON and wait at least 5 seconds.
- Check 1st trip DTC.
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
- Turn ignition switch OFF.
- Disconnect mass air flow sensor (with intake air temperature sensor) harness connector.
- Turn ignition switch ON.
- Check the voltage between mass air flow sensor harness connector and ground.
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK INTAKE AIR TEMPERATURE SENSOR POWER SUPPLY CIRCUIT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between mass air flow sensor harness connector and ECM harness connector.
- Also check harness for short to ground.
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
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between mass air flow sensor harness connector and ECM harness connector.
- Also check harness for short to power.
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
- Turn ignition switch OFF.
- Disconnect mass air flow sensor harness connector and reconnect it again.
- Turn ignition switch ON.
- Select “DATA MONITOR” mode with CONSULT.
- Check that “INT/A TEMP SEN” indicates as per following condition.
| 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".
