Depends. The SCT. Has a built-in reader & gives P0140, but the Eqquis at O'Reilly's gives P0172. They are actually similar results, involving O2 sensors detecting a rich mix. Once I reset it, it runs fine on the next start up, I could drive til the tank is empty & it won't pop a code. But once I shut down, the next time I start it up, I get the code after 3-4 minutes, then it runs rich until I reset it.
It gets more complicated than that, but That's it in a nut shell.
