two observations - Toyota Yaris Forums

I doubt the Yaris has a sensor for the true outside air temperature that a reader like a Scanguage can display. The stock air cleaner takes in air from a point behind the radiator, and the intake air temperature sensor is in the throttle body. It will read the ambient temperature while the engine is warming up, but after the thermostat opens it will be breathing somewhat warmer air.

The thing I really miss from the Volvo I traded in is the data display. But I can't quite bring myself to use a kludgy add-on like a Scangauge. My dad would have. He punched a hole in the dash of his Diesel Chevette and mounted a mechanical tach on top of it.
