note When removing the vacuum hose, always make a mark so that it can be reconnected at original position.
1.Remove vacuum hoses from the purge control solenoid valve.
2.Disconnect the purge control solenoid valve connector.

3.Connect a hand vacuum pump to nipple (A) of the solenoid valve (refer to the illustration at left).
4.Check airtightness by applying vacuum with voltage applied directly from the battery to the solenoid valve and without applying voltage.
