Diagnostic Test

1. Turn ignition switch OFF.
2. Disconnect intake valve timing control solenoid valve harness connector.
3. Check resistance between intake 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 STEP 2  .

NO 

Replace malfunctioning intake valve timing control solenoid valve. Refer to EXPLODED VIEW WITH TORQUE SPECIFICATIONS .

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. Check that the plunger moves as shown in the figure.

   CAUTION:

   Never 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.

   NOTE:

   Always replace O-ring when intake valve timing control solenoid valve is removed. 

Is the inspection result normal?
