IDLE-UP SOLENOID VALVE CHECK



1.Disconnect the vacuum hoses (white stripes, yellow stripes) from the solenoid valve.
2.Disconnect the harness connector.

3.Connect a manual vacuum pump to the nipple A.

4.Check air-tightness by applying a vacuum with voltage applied directly from the battery to the solenoid valve terminal and without applying voltage.
Battery voltage
Nipple B
Vacuum condition
Applied
Open
Vacuum leaks from nipple B
Blocked with finger*1
Vacuum is maintained
Not applied
Open
Vacuum is maintained
Blocked with finger*2
note In case of mark*1, a vacuum can be felt but in case of mark*2, a vacuum cannot be felt.

5.Measure the resistance of the solenoid valve.
Standard value: Approximately 40Ω
6.When disconnecting the vacuum hose, always make a mark so that the hose can be reconnected at original position.
