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.
