Turn ignition switch ON.
Check the voltage between IVT intermediate lock control solenoid valve harness connector and ground.

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

Turn ignition switch OFF.
Disconnect IPDM E/R harness connector.
Check the continuity between IVT intermediate lock control solenoid valve harness connector and IPDM E/R harness connector.

Check IVT intermediate lock control solenoid valve power supply circuit

Also check harness for short to ground.

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

Turn ignition switch OFF.
Disconnect ECM harness connector.
Check the continuity between IVT intermediate lock control solenoid valve harness connector and ECM harness connector.

Check IVT intermediate lock control solenoid valve ground circuit

Also check harness for short to ground and short to power.

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

Turn ignition switch OFF.
Disconnect intake valve timing control solenoid valve harness connector.
Check resistance between intake valve timing control solenoid valve terminals as follows.

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

Remove intake valve timing control solenoid valve. Refer to EM-44, "Exploded View".
Provide 12 V DC between intake valve timing control solenoid valve terminals 1 and 2, and then interrupt it. 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 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".

Check intake valve timing control solenoid valve-II
