The scangauge shows intake air temp(IAT). The temp of the air going into the engine. On newer rangers, it's a sensor in the MAF(Mass airflor meter) and in older models it's it's own seperate sensor generally located closer to the throttle body. Intake temp is almost always cooler than ambient temp(outside temp) when traveling because there's cooler air being shoved in(ram air effect), resulting in a lower temp. When parked, that number will rise with engine heat as there's no ram air effect.

On a 60* day, at about 75mph my IAT is about 40*.
that my friend is what i was trying to say !
