Component Inspection

CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-I

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

RESISTANCE SPECIFICATION

Terminals	Resistance
1 and 2	6.7 - 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 intake valve timing control solenoid valve.

CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II
1. Remove intake valve timing control solenoid valve.
2. Provide 12 V DC between intake valve timing control solenoid valve terminals 1 and 2, and then interrupt it. Make sure 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 intake valve timing control solenoid valve.

Is the inspection result normal?

YES: INSPECTION END

NO: Replace intake valve timing control solenoid valve.
