Component Inspection

CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-I

Turn ignition switch OFF.
Disconnect exhaust valve timing control solenoid valve harness connector.
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 "EXPLODED VIEW ".

CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-II
1. Remove exhaust valve timing control solenoid valve. Refer to "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.
