Yaris T1 Throttle Body Question

[SirDigby]

actually, the real reason there is coolant running to the throttle body is that: under a certain load, in certain humid areas, at certain times of the year, at certain elevation, at a certain RPM there may be a sight chance of maybe wet enough air in a certain vortex might form ice inside the manifold and on the throttle body, maybe. so we should heat up the throttle body just in case.
