robertgrove from WeGo2U Mobile Mechanic, February 10, 2013, 19:49ReplyEnthusiastThe EGR Modulator works along with EGR Valve and Vacuum Solenoid to control the amount of EGR flow into the engine. EGR flow cools the combustion temp and reduce NOX emissions. Vacuum lines from the EGR and vacuum solenoid go to the modulator.
The picture in my facebook post: http://www.facebook.com/photo.php?fbid=472075606173934&am... shows the modulator, EGR valve and vacuum solenoid, this should help you find it on your car
Enjoy!
