EGR Solenoid Vacuum Valve Assembly

The dual EGR solenoid valve assembly consists of one vacuum valve that supplies vacuum to the EGR valve when it is energized and a vent valve that vents EGR vacuum to the atmosphere when de-energized. Both valves receive signals from the ECU. A restrictor is added in the vacuum valve inlet port so that the vent valve may vent if the vacuum valve sticks open.
