Default HELP with check engine light!

I pulled the code on my 94 GT and it was a bad TPS, so i replaced it. The light shut itself off, but then a week later came back on. WHY IS THIS???
I checked everything i pulled apart and nothing has come loose. Why would it come back on after a week? Should i try disconnecting the battery to see if it might shut it off?
