If the coolant thermostat sticks open, what happens is the engine
runs cooler than it should...thermal losses are higher and tolerances
are closer(ie more friction.)  Both affect mileage, thermal loss much
more so.  It's one of the reasons you get really crappy mileage on
short in-city driving(ie to the local corner store etc.)

However, if you mean the temperature sensor on the back of the
engine, yeah, that'll affect mileage...if it goes south, the ECU
assumes a really hot temperature.
