NO >> Replace crankshaft position sensor. Refer to EM-103, "Exploded View".
4.CHECK EXHAUST CAMSHAFT POSITION SENSOR
Check the exhaust camshaft position sensor. Refer to EC-662, "Component Inspection".
Is the inspection result normal? YES >> GO TO 5.
NO >> Replace exhaust valve timing control position sensor. Refer to EM-78, "Exploded View".
5.CHECK CAMSHAFT (EXHAUST)
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-79, "Removal and Installation".
6.CHECK TIMING CHAIN INSTALLATION

NO >> Clean lubrication line.
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 exhaust valve timing control solenoid valve. Refer to EM-67, "Exploded View".
2.CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-II
1. Remove exhaust valve timing control solenoid valve.
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-67, "Exploded View".
