How does a car measure the outside temperature at speed, without it skewing for windchill or engine/surface heat?
In: 92
The temperature sensor is typically installed either in the front bumper or in the side view mirror. Either location provides some protection from wind/airspeed effects and is out of the way from the engine. You may notice that after you get your car washed that the temperature drops for a bit and that’s due to evaporative cooling on the temperature sensor..
