Component Inspection

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.

   Terminals	Resistance
   1 and 2	7.0 - 7.7 Ω [at 20°C (68°F)]
   1 or 2 and ground	∞Ω (Continuity should not exist)

Is the inspection result normal?

YES>>

GO TO 2.

NO>>

Replace malfunctioning exhaust valve timing control solenoid valve. Refer to TIMING CHAIN : Exploded View .

1. Remove exhaust valve timing control solenoid valve. Refer to TIMING CHAIN : 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, below.

   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.
