On a warm summer day, it usually displays a temperature significantly higher than the actual temperature, and there are several reasons why. For starters, your car does not actually have a built-in thermometer.
How is "outside temperature" measured in a car?

The sensor works by measuring the temperature that's being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on ...
How do cars measure outside temperature?
Cars use a device called a thermistor to measure temperature, by measuring the changes in electrical current when heat is added or removed. Most thermistors are located behind the grille on the front of the car, meaning they're fairly close to the road surface, which can affect the measurements.
Does the car measure temperature inside or outside?
Your car actually has a thermistor – not a thermometer. Car thermistors are a poor representation of the actual outside temperature. This is because the thermistor is exposed to re-radiated heat from the road surface.
