Mine does it too, From what i have read on this board it is normal, and won't harm anything. There was apparently a TSB for it, but it has since expired

I had the same thing two years ago, it's the charcoal emissions canister .....
There was a continual "buzzing" sound from around the area of the battery and evaporative canister at the front left fender area. There is a Toyota TSB #EG002-97 "EVAP CHARCOAL CANISTER NOISE" that calls for a small $17 expansion plenum to be sticky-backed to the canister and connected into the tubing. The buzzing sound then goes away.
