Question: Where Is The Outside Temperature Sensor Located On A Car?

Generally, the outside temperature sensor is located under the front of the hood near the bottom of the car. Although the sensor itself is accurate, the location causes the sensor to pick up heat from the road surface.

Why is my car reading the wrong outside temperature?

Most cars these days have 2 sensors: one inside and one outside. The sensor that measures outside temperature is typically up behind the bumper, which is near the hot asphalt and the engine. That’s why it reads a little higher that what the temperature actually is outside.
