Are you sure the O2 and egr was bad and how did you find this out? If you guessed. You maybe wrong. The prob may still be there. If you got the info from a Obd2 scanner. That's a little diffrent. If you dident get the info from a shop or scanner. Start there. If you did there's 2 things you can do. #1 unhook the pos from the battery. For a min or two. Doing this will reset the computer. But you will loose memory in your raido. If there still a prob the light will come back on after 50 miles or so. Then back to square one. #2 take it to a shop and and have them plug it in and they can rest the system with out loosing things. I think it would. Be in your best intrest to take. It to a shop and let them plug it in to element all doubt. Hope this helps

you dont need to buy a code reader for this van, If you planing to work on your van yourself, then you should get a haynes manual from a auto parts store, its not expensive and you will find more detailed info about how to read your codes. hope this helps.
