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".
