2.Check 1st trip DTC.
Is 1st trip DTC detected?
YES- Proceed to "Diagnosis Procedure" .
NO- INSPECTION END


Diagnosis Procedure


1. CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE POSITION SENSOR POWER SUPPLY

1.Turn ignition switch OFF.
2.Disconnect intake valve manifold runner control valve position sensor harness connector.
3.Turn ignition switch ON.
4.Check the voltage between intake valve manifold runner control valve position sensor harness connector.





Is the inspection result normal?
YES- GO TO 4.
NO- GO TO 2.

2. CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE POSITION SENSOR POWER SUPPLY CIRCUIT
Check the voltage between intake valve manifold runner control valve position sensor harness connector and ground.





Is the inspection result normal?
YES- GO TO 3.
NO- Perform the trouble diagnosis for power supply circuit.

3. CHECK ECM GROUND CIRCUIT

1.Turn ignition switch OFF.
2.Disconnect ECM harness connector.
3.Check the continuity between ECM harness connector and ground.





*1: Except for California
*2: For California
4.Also check harness for short to power.
Is the inspection result normal?
YES- Check intermittent incident. Refer to "Intermittent Incident" Intermittent Incident.
NO- Repair or replace error-detected parts.

4. CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE POSITION SENSOR GROUND CIRCUIT

1.Turn ignition switch OFF.
2.Disconnect ECM harness connector.
3.Check the continuity between intake manifold runner control valve position sensor harness connector and
ECM harness connector.





*1: Except for California
*2: For California
4.Also check harness for short to power.
Is the inspection result normal?
YES- GO TO 5.
NO- Repair or replace error-detected parts.

5. CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE POSITION SENSOR INPUT SIGNAL CIRCUIT

1.Check the continuity between intake manifold runner control valve position sensor harness connector and
ECM harness connector.





*1: Except for California
*2: For California
2.Also check harness for short to ground and to power.
Is the inspection result normal?
YES- GO TO 6.
NO- Repair or replace error-detected parts.

6. CHECK INTERMITTENT INCIDENT

Perform "Intermittent Incident" Intermittent Incident.
Is the inspection result normal?
YES- Replace intake manifold assembly. Refer to "Exploded View" Exploded View.
NO- Repair or replace error-detected parts.
