Toyotas of this vintage usually have several "vacuum switching valves" that open and close in part based on the coolant temperature. Some (the charcoal canister one, in particular) aren't even electronic - they just open or close when the coolant temp gets above or below a certain level.

One of those could easily be disconnected from its hose, causing all of this hand wringing. Less than 30 seconds of effort required to fix it.
