3.CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE

Check the exhaust valve timing control solenoid valve. Refer to EC-179, "Component Inspection".

Is the inspection result normal? YES >> GO TO 4.

NO >> Replace exhaust valve timing control solenoid valve. Refer to EM-44, "Exploded View".

4.CHECK CRANKSHAFT POSITION SENSOR (POS)

Check the crankshaft position sensor (POS). Refer to EC-297, "Component Inspection (Crankshaft Position sensor)".

Is the inspection result normal? YES >> GO TO 5.

NO >> Replace crankshaft position sensor (POS). Refer to EM-92, "Exploded View".

5.CHECK EXHAUST VALVE TIMING CONTROL POSITION SENSOR

Check the exhaust valve timing control position sensor. Refer to EC-387, "Component Inspection".

Is the inspection result normal? YES >> GO TO 6.

NO >> Replace exhaust valve timing control position sensor. Refer to EM-44, "Exploded View".

6.CHECK CAMSHAFT (EXH)

Check the following.

Is the inspection result normal? YES >> GO TO 7.

NO >> Remove debris and clean the signal plate of camshaft rear end or replace camshaft. Refer to EM-64, "Removal and Installation".

Check camshaft

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. Refer to EM-45, "Removal and Installation".

NO >> GO TO 8.

8.CHECK LUBRICATION CIRCUIT

Refer to LU-7, "Inspection".

NO >> Clean lubrication line.

9.CHECK INTERMITTENT INCIDENT

Refer to GI-41, "Intermittent Incident".

>> INSPECTION END

Component Ins

1.CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-1

  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.

Check exhaust valve timing control solenoid valve-1

Check exhaust valve timing control solenoid valve-1

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

NO >> Replace exhaust valve timing control solenoid valve. Refer to EM-44, "Exploded View".

2.CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-2

  1.  Remove exhaust valve timing control solenoid valve. Refer to EM-44, "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 exhaust valve timing control solenoid valve. Refer to EM-44, "Exploded View"
