EGR Solenoid Valve (Justy Carbureted & Loyale)

1. Remove connector from solenoid valve. Measure resistance of solenoid valve. Resistance should be 33-40 ohms. If resistance is not 33-40 ohms, replace solenoid valve. Measure resistance between solenoid valve terminal leads and body ground. If solenoid is shorted, replace solenoid valve.
2. Check vacuum passage for opening and closing operation. When EGR solenoid is not energized, passage between "A" and "B" should be closed and passage between "B" and "C" should be open. When solenoid is energized, passage between "A" and "B" should be open and passage between "B" and "C" should be closed. See Fig 1 .
