The AOS will not trigger a CEL directly. It is likely that the code is thrown due to unacceptable differences in reading between pre and post cat O2 sensors. It is also possible your O2 sensors have been cooked from all the smoke created by burning oil. Only by plugging it into the computer and reading the codes will you know for sure though.
To answer your question, not much can be done to bypass AOS or plug it up. Driving with the smoke can damage O2 sensors and cats. In saying that, I drove mine in this state for about a week with no ill effects, although I am completely catless and only have one set of O2 sensors. Just remember to check oil daily if you drive it. You may be using as much a 2 quarts per week if it is severe.
