What we have on the Sienna's (2nd gen) is an all in one IAC/cruise/throttle motor. I've never seen anyone complain about these failing before and would question the diagnosis. At any rate the cheap option would be to buy used, whether at your local junk yard or ebay.

bsedgal is correct - there isn't a separate IAC on a 'fly by wire' throttle. The electronic throttle sets the plate at a paper thin opening to support an idle air flow. But you do have to keep it clean for it to work properly.
