1.Disconnect the vacuum hose
from the solenoid valve. 2.Disconnect the harness
connector. 3.Connect a hand vacuum pump to nipple
(A) of the solenoid valve (refer to the illustration
at left). 4.Check air tightness by applying a
vacuum with voltage applied directly from the battery
to the exhaust gas recirculation control solenoid valve and
without applying voltage.
