Diagnosis Procedure
1.CHECK INTAKE VALVE TIMING (IVT) CONTROL SOLENOID VALVE POWER SUPPLY

Is the inspection result normal? YES >> GO TO 3.
NO >> GO TO 2.
2.CHECK IVT 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 IVT CONTROL SOLENOID VALVE GROUND CIRCUIT

Is the inspection result normal? YES >> GO TO 4.
NO >> Repair or replace error-detected parts.
4.CHECK IVT CONTROL SOLENOID VALVE
Check the IVT control solenoid valve. Refer to EC-193, "Component Inspection (IVT Control Solenoid Valve)".
Is the inspection result normal? YES >> GO TO 5.
NO >> Replace IVT control solenoid valve. Refer to EM-44, "Exploded View".
5.CHECK IVT INTERMEDIATE LOCK CONTROL SOLENOID VALVE POWER SUPPLY

Is the inspection result normal? YES >> GO TO 7.
NO >> GO TO 6.
6.CHECK IVT INTERMEDIATE LOCK 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.
7.CHECK IVT INTERMEDIATE LOCK CONTROL SOLENOID VALVE GROUND CIRCUIT

Is the inspection result normal? YES >> GO TO 8.
NO >> Repair or replace error-detected parts.
8.CHECK IVT INTERMEDIATE LOCK CONTROL SOLENOID VALVE
Check the IVT intermediate lock control solenoid valve. Refer to EC-194, "Component Inspection (IVT Intermediate Lock Control Solenoid Valve)".
Is the inspection result normal? YES >> GO TO 9.
NO >> Replace IVT intermediate lock control solenoid valve. Refer to EM-64, "Exploded View".
9.CHECK INTERMITTENT INCIDENT
Refer to GI-41, "Intermittent Incident".
>> INSPECTION END
Component Inspection (IVT Control Solenoid Valve)
1.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I

Is the inspection result normal? YES >> GO TO 2.
NO >> Replace intake valve timing control solenoid valve. Refer to EM-44, "Exploded View".
2.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II
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-44, "Exploded View".

Component Inspection (IVT Intermediate Lock Control Solenoid Valve)
1.CHECK INTAKE VALVE TIMING INTERMEDIATE LOCK CONTROL SOLENOID VALVE-I

Is the inspection result normal? YES >> GO TO 2.
NO >> Replace intake valve timing intermediate lock control solenoid valve. Refer to EM-44, "Exploded View".
2.CHECK INTAKE VALVE TIMING INTERMEDIATE LOCK CONTROL SOLENOID VALVE-II
Make sure that the plunger moves as shown in the figure.
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 intermediate lock control solenoid valve.
NOTE: Always replace O-ring when intake valve timing intermediate lock control solenoid valve is removed.
Is the inspection result normal?
YES >> INSPECTION END
