Diagnosis Procedure

1.CHECK OIL PRESSURE WARNING LAMP

1. Start engine.
2. Check oil pressure warning lamp and confirm it is not illuminated.

Is oil pressure warning lamp illuminated?

YES >> Go to LU8, "Inspection".

NO >> GO TO 2.

2.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE

Refer to EC, "Component Inspection".

Is the inspection result normal?

YES >> GO TO 3.

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

3.CHECK CRANKSHAFT POSITION SENSOR

Refer to EC, "Component Inspection".

Is the inspection result normal?

YES >> GO TO 4.

NO >> Replace crankshaft position sensor. Refer to EM, "Exploded View".

4.CHECK INTAKE CAMSHAFT POSITION SENSOR

Refer to EC, "Component Inspection".

Is the inspection result normal?

YES >> GO TO 5.

NO >> Replace intake camshaft position sensor. Refer to EM, "Exploded View".

5.CHECK CAMSHAFT (INTAKE)

Check the following.

• Accumulation of debris to the signal plate of camshaft rear end
• Chipping signal plate of camshaft rear end

Is the inspection result normal?

YES >> GO TO 6.

NO >> Remove debris and clean the signal plate of camshaft rear end or replace camshaft. Refer to EM, "Removal and Installation".

6.CHECK TIMING CHAIN INSTALLATION

Check service records for any recent repairs that may cause timing chain misaligned.

Are there any service records that may cause timing chain misaligned?

YES >> Check timing chain installation. Refer to EM, "Removal and Installation".

NO >> GO TO 7.

7.CHECK LUBRICATION CIRCUIT

Perform "Inspection of Camshaft Sprocket (INT) Oil Groove". Refer to EM, "Inspection".

Is the inspection result normal?

YES >> GO TO 8.

NO >> Clean lubrication line.

8.CHECK INTERMITTENT INCIDENT

Refer to GI, "Intermittent Incident".

>> INSPECTION END

Component Inspection

1.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVEI

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 follows.

Is the inspection result normal?

YES >> GO TO 2.

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

2.CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVEII

1. Remove intake valve timing control solenoid valve. Refer to EM, "Exploded View".
2. Apply 12 V 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 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 Oring 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, "Exploded View
