    It opens a butterfly valve on the drivers side exhaust manifold that creates more backpressure which forces some more of the exhaust towards the EGR valve. When its activated it closes partially and when off it opens all the way. Id leave it disconnected and plug the line unless youre worried about emissions. If so, make sure it and the EGR are plugged in and operable.
