The 420 will not go away with egr replacement. it means the computer has detected a problem with the catalytic converter. eGR valve is at the rear of the engine. Not easy to get to on vans.

there are two ways to reset the light. you can use an obd2 scan tool to read and reset it or you can pull your battery cables off for a half hour and that will also reset it. just be forewarned if you have not fixed the problem that turned it on in the first place it will just come back on. if you have fixed the problem after 50 starts without seeing the issue again it will also clear itself.

check the vacuum line on the right side of the engine. There should be an elbow connector connecting the line to the engine. Does interior fan only come out of the defroster vents by chance?

404 is exhaust gas recirculation circuit, and 405 is exhaust gas recirculation sensor circuit low. EGR sensor or ground?
