I can't answer either question. I do know that the throttle
body and MAF sensor do have codes of their own, although
not for being dirty, meaning it's not going to read "Dirty Throttle
Body" or "Dirty MAF Sensor."

But, what I wanted to tell you is that if you do clean your throttle
body by the way some people suggest which is just disconnecting
the hose and spraying it down and then running the engine, plan on
doing an oil change in the next couple of hundred miles. I do mines
by totally disconnecting the throttle body and cleaning it down with
the spray and a toothbrush plus a bunch of rags. You can really
get it clean that way and you don't have the liquid being sucked in
to the engine. Again, that isn't a big problem if you change the oil
soon after doing it.
