Exhaust Flap

Well, seems I have this problem too. Something hit mine and broke the plug off, CEL came on and so I pulled the codes. To make a long story short I drove it up on some ramps and crawled under to see what was up, the plug was hanging so I was going to pull it off and tie it up. When I did so the wires touched briefly and now I have a flashing GP light with a P2111 code. (Key was on when I pulled Wires) I also had to reset drivers side window memory and speed warning on the MFI. Not sure why but I did. I cleared the code but it keeps coming back. So anyone know what happened? Is there a fuse somewhere? Need to be "reset" bigger question is what would it have to do with window memory? I would like to get rid of that flashing GP light. Car works the same as always BTW.
Someone please answer. I know there is a guru there somewhere.
