DTC CONFIRMATION PROCEDURE


DTC CONFIRMATION PROCEDURE

1.PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds

>> GO TO2.

2.PERFORM DTC CONFIRMATION PROCEDURE

1. Start engine and let it idle for 5 seconds.

2. Check 1st trip DTC.

Is 1st trip DTC detected? YES >> Proceed to EC-176,

Diagnosis Procedure

1.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE POWER SUPPLY

1. Turn ignition switch OFF.

2. Disconnect intake valve timing (IVT) control solenoid valve harness connector.

3. Turn ignition switch ON.

4. Check the voltage between intake valve timing control solenoid valve harness connector and ground.

Is the inspection result normal?


Is the inspection result normal? YES >> GO TO 3.

NO >> GO TO 2.

2.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect IPDM E/R harness connector.

3. Check the continuity between IVT control solenoid valve harness connector and IPDM E/R harness connector.

4. Also check harness for short to ground.


4. 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.

3.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE GROUND CIRCUIT

1. Turn ignition switch OFF.

2. Disconnect ECM harness connector.

3. Check the continuity between IVT control solenoid valve harness connector and ECM harness connector.

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


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

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-177, "Component Inspection".

Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-42, "Intermittent Incident".

NO >> Replace intake valve timing control solenoid valve.

Component Inspection

1.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I

1. Turn ignition switch OFF.

2. Disconnect intake valve timing control solenoid valve harness connector.

3. Check resistance between intake valve timing control solenoid valve terminals as per the following.

Is the inspection result normal?


Is the inspection result normal? YES >> GO TO 2.

NO >> Replace intake valve timing control solenoid valve. Refer to EM-67, "Exploded View".

2.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II

1. Remove intake valve timing control solenoid valve. Refer to EM-67, "Exploded View".

2. 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-67, "Exploded View".
