    most cars are behind the front bumper, everyone I've seen actually. it must be out of the direct airflow when the car is moving & out of direct sunlight. The only issues with this location is that if your car is ideing for a long period of time it can get heat soaked & show slightly higher than actual. This WILL happen even with factory installs, but seams to be the best location...............

    Turbocad is right on! GM mounts theirs in front of the radiator behind the grille. Saab has also placed theirs there since they started using them in 1986, but they place theirs lower. Our TT and VW place them in the same locale as the Saabs.

    Again - spot on info! The manufacturers in recent years have applied logic to the temp reading. They sample the ambient temp sensor when sitting for extended periods but do not display the drastic temperature changes caused by heat radiating from the road as well as the cooling system/radiator. A nice piece of logic to apply to your creation, as well.
    My first attempt at a carputer.

    PM me if you're interested in a monitor faceplate for your '99-'04 Golf or Jetta. My Vortex ID is NorthAtlR32 - you can IM me there, too. Go here for more information.

    outside temp sensor

    On the Dodge Sprinter (05, not sure about the rest), the outside temp sensor is inside/behind the front license plate mount.
