You didnt give year and engine of your Previa. But I'm going to assume that it's supercharged (S/C) model. Superchargers are notorious for supercharger whine or whistling. Also it could be a vacuum leak, or a loose air filter seal letting air in.
Another possibility is a restriction in the exhaust. I have a 95 with this feature -- it has whistled ever since the rear catalytic converter rusted out and had to be replaced. Some piece of this is probably stuck in the muffler and causing the whistle whenever there's enough air (exhaust) moving past it.
