Diagnosis Procedure


1. CHECK OIL PRESSURE WARNING LAMP

1.Start engine.





2.Check that oil pressure warning lamp is not illuminated.
Is oil pressure warning lamp illuminated?
YES- Go to Inspection.
NO- GO TO 2.

2. CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE

.
Is the inspection result normal?
YES- GO TO 3.
NO- Replace malfunctioning exhaust valve timing control solenoid valve. Exploded View.

3. CHECK EXHAUST VALVE TIMING CONTROL POSITION SENSOR

P1078.
Is the inspection result normal?
YES- GO TO 4.
NO- Replace malfunctioning exhaust valve timing control position sensor. Exploded View.

4. CHECK CRANKSHAFT POSITION SENSOR

P0335.
Is the inspection result normal?
YES- GO TO 5.
NO- Replace crankshaft position sensor. Exploded View.

5. CHECK CAMSHAFT POSITION SENSOR

P0340.
Is the inspection result normal?
YES- GO TO 6.
NO- Replace malfunctioning camshaft position sensor.Exploded View.

6. CHECK CAMSHAFT (EXH)

Check the following.





- Accumulation of debris to the signal plate of camshaft front end
- Chipping signal plate of camshaft front end
Is the inspection result normal?
YES- GO TO 7.
NO- Remove debris and clean the signal plate of camshaft front end or replace camshaft. Exploded View.

7. 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. Disassembly And Assembly.
NO- GO TO 8.

8. CHECK LUBRICATION CIRCUIT

Perform "Inspection of Camshaft Sprocket (EXT) Oil Groove". Inspection.
Is the inspection result normal?
YES- GO TO 9.
NO- Clean lubrication line.

9. CHECK INTERMITTENT INCIDENT

Intermittent Incident.
- INSPECTION END


Component Inspection


1. CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-I

1.Turn ignition switch OFF.
2.Disconnect exhaust valve timing control solenoid valve harness connector.
3.Check resistance between exhaust valve timing control solenoid valve terminals as per the following.





Is the inspection result normal?
YES- GO TO 2.
NO- Replace malfunctioning exhaust valve timing control solenoid valve. Exploded View.

2. CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-II

1.Remove exhaust valve timing control solenoid valve. Exploded View.





2.Provide 12 V DC between exhaust valve timing control solenoid valve terminals 1 and 2, and then interrupt it. Check 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 exhaust valve timing control solenoid valve.
NOTE:
Always replace O-ring when exhaust valve timing control solenoid valve is removed.
Is the inspection result normal?
YES- INSPECTION END
NO- Replace malfunctioning exhaust valve timing control solenoid valve. Exploded View.
