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-180, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE POWER SUPPLY
Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE 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 VALVE TIMING CONTROL SOLENOID VALVE GROUND CIRCUIT
Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE
Check the intake valve timing control solenoid valve. Refer to EC-181, "Component Inspection (IVT Control Solenoid Valve)".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Replace intake valve timing control solenoid valve. Refer to EM-48, "Exploded View".
Component Inspection (IVT Control Solenoid Valve)
1.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-1
Is the inspection result normal? YES >> GO TO 2.
NO >> Replace intake valve timing control solenoid valve. Refer to EM-48, "Exploded View".
2.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-2
CAUTION:
Do not apply 12 V DC continuously for 5 seconds or more.
Doing so may result in damage to the coil in intake valve timing control solenoid valve.
NOTE:
Always replace O-ring when intake valve timing control solenoid valve is removed.
Is the inspection result normal? YES >> INSPECTION END
NO >> Replace intake valve timing control solenoid valve. Refer to EM-48, "Exploded View".

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. To judge the malfunctions of heated oxygen

Inspection and Adjustment
INSPECTION
Perform inspection after removal, installation or replacement of camshaft or
valve-related parts, or if there are
unusual engine conditions regarding valve clearance.
Remove rocker cover. Refer to EM-46, "Exploded View".
