I'm telling you....it's part of the emissions controls....it's the air pump..mounted to the front of the engine....It pumps fresh air into the exhaust manifolds to help light off the catalyst faster during cold starts....that's the high pitched noise...and it's also why your headlights will flicker during a cold start @ night...
but If you want to check it, it's located right under the headlights on the drivers side. You could raise the lights and listen in that area, or jack the front of the car up, and remove the outer plastic piece under the bumper and actually see it.

Not sure if that's it, because mines be shut off, (and now removed) for a LONG time, so I don't remember what it even sounds like but If you want to check it, it's located right under the headlights on the drivers side.
