DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at least 10 seconds before conducting the next test.
TESTING CONDITION:
>> GO TO 2.
2.PERFORM DTC CONFIRMATION PROCEDURE
With CONSULT
If not, cool engine down or warm engine up until “COOLANT TEMP/S” indicates between −7В°C (19В°F) to 60В°C (140В°F). Then go to the following steps.
With GST
Following the procedure “With CONSULT” above.
Is 1st trip DTC detected? YES >> Proceed to EC-413, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE MOTOR POWER SUPPLY
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE MOTOR 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 MANIFOLD RUNNER CONTROL VALVE MOTOR OUTPUT SIGNAL CIRCUIT
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE MOTOR
Check the intake manifold runner control valve motor. Refer to EC-414, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace intake manifold assembly. Refer to EM-27, "Removal and Installation".
Component Inspection
1.CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE
With CONSULT
If not, cool engine down or warm engine up until “COOLANT TEMP/S” indicates between −7В°C (19В°F) to 60В°C (140В°F). Then go to the following steps.
With GST
Following the procedure “With CONSULT” above.
Is 1st trip DTC detected? YES >> Replace intake manifold assembly. Refer to EM-27, "Removal and Installation".
NO >> GO TO 2.
2.CHECK INTAKE MANIFOLD RUNNER CONTROL VALVE MOTOR
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace intake manifold assembly. Refer to EM-27, "Removal and Installation".

DTC DETECTION LOGIC
The heated oxygen sensor 2 has a much longer switching time between rich and
lean than the air fuel ratio (A/
F) sensor 1. The oxygen storage capacity of the three way catalyst (manifold)
causes the longer switching
time.
