EGR Control Solenoid: Description and Operation
EGR valve position sensor
The dual EGR solenoid valve assembly consists of two dithering solenoid valves, Fig. 7. The first is a vacuum valve which supplies vacuum to the
sonic EGR valve when energized. The second is a vent valve which vents the EGR valve to the atmosphere when de-energized. Both solenoid valves
receive variable duty cycle signals from the EEC system according to EGR requirements.
