Understood, but the particular code I'm getting is that the *heating element* in the oxygen sensor is what's not working. My expectation is that's a pretty specific input line that the computer is monitoring. So though those are still possibilities, I expect it's still actually something related to that part.

I'll also try the battery disconnect thing too, if I can't find a blown fuse.
