EXHAUST GAS RECIRCULATION CONTROL SOLENOID VALVE CHECK <6G72>


note When disconnecting the vacuum hose, always make a mark so that it can be reconnected at original position.


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.
