CHECK INTAKE VALVE TIMING CONTROL SOLENOID VALVE-II

1. Remove intake valve timing control solenoid valve. Refer to 

EM-49, "Exploded View"

.

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.

NOTE:

Always replace O-ring when intake valve timing control

solenoid valve is removed.

Is the inspection result normal?

YES

>> INSPECTION END

NO

>> Replace intake valve timing control solenoid valve. Refer to
