I recommend everyone get a scan tool.  All aren't created equal and in general a bluedriver (not counterfeit) is what I recommend as a minimum.  I'd also try this, "disconnect ground cable from battery and let it sit disconnected for a few hours.  Reconnect sharply and firmly (preventing a lot of sparks that can be interpreted as signals by the ecm).  And hopefully it'll reset your ecm to a correct programmed state.  Else likely will require an oem scan to reset/reprogram correctly.  However, check forum for your specific car as there may be a better scan tool for it that will allow this/more functions... if battery disconnect doesn't resolve.
