Check Engine Light

I have a 2002 Trooper. The check engine light is on. I had the EGR Valve changed and the gas cap. It is still on ??????

scanner

go to your local parts store and use a scanner in order to acquire the codes
some codes are minor such as the cayatltic converter needs replacing. only way to be sure is to get the scanner. i personnaly bought one so i can have it at all times.
