Where is my outside temperature gauge located

I have a computer in my car that tells the outside air temperature and gas mileage among other things. For the last couple of years in the summer the air temperature is never right. You first had to subtract 10 degrees then it went to 6 degrees. This winter the temperature sensor registered that it was 135 degrees out! Can you tell me where the sensor is on the outside of the car? That would be greatly appreciated.
Thanks
