PURGE CONTROL SOLENOID VALVE CHECK


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




1.Disconnect the solenoid valve from the inlet manifold.
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 airtightness by applying a vacuum with voltage applied directly from the battery to the purge control solenoid valve and without applying voltage.
Battery voltage
Normal condition
Applied
Vacuum leaks
Not applied
Vacuum maintained
5.Measure the resistance between the terminals of the solenoid valve.
Standard value: 22 - 26 Ω (at 20°C)
