Location of smog air pump 07 QP

Starting to hear a odd whine noise which I suspect is the smog air pump on a few seconds after cold start ups. Goes away about the expected time the pump would typically turn off. No check engine lights so pumps still operating ok, just sounds odd. Where exactly does it reside in the engine bay as I have not looked just yet.

I think I know the answer to this but if one disconnected that air pump, to eliminate the whistle at startup, would it throw an error code?
