It takes almost 10 mins. to read correctly in the winter coming out of the heated garage.

The thermometer in your car contains basically the same ingredient as a sophisticated weather station: a thermistor. These are highly accurate sensors that produce electricity based on ambient temperature.

The major difference is the environment surrounding the temperature sensor. When we place our weather station sensors, we go to pains to avoid re-radiated heat. So our sensors are solar-shielded and located at least ten feet away from trees, fences, buildings, concrete and asphalt. We also take care not to locate sensors in stagnant air corridors.

Often this means a sensor out on a lawn or dirt, on a post five feet above the ground.

This allows us to meet National Weather Service standards, and the National Weather Service receives data from many of our locations on an hourly basis.

Car thermometers obviously don't operate in this kind of environment. Neither do those bank signs and billboards.

In particular, a car is a very difficult environment for a temperature sensor. That the sensors are located as well as they are are a testament to careful consideration on the part of the engineers. There is engine heat to worry about, plus re-radiated heat from the concrete and asphalt roads, paint, tires, etc.

It's also very possible to locate a weather station sensor poorly. I've seen many of these sensors incorrectly mounted on roofs. Think about the re-radiated heat a roof gives off, and what that must do to distort readings.

So think of your car temperature sensor as a ballpark figure. It's accurate for its environment, but that is it. On cooler days, it may only be different from more carefully placed weather station sensors by a degree or two. But on days like yesterday, an excess of re-radiated heat likely exaggerates those differences.

The readings are consistently lower than the air temp. (I have a calibrated thermometer on my front porch which is about 20 feet from the car in the driveway.)
On HOT sunny days we don't get much variation in air temp from place to place locally.
It's a frying pan everywhere.

Plus the temps are much lower than the air temp. when I 1st start the car at mid-morning or past noon.
The engine is air temp cold at that time.

Remember that the car thermometer usually reads less than the air temp.
I could understand if it read more, but I've never seen that except those times in the winter.

I have a 2008 Nissan Rogue SL, I have been trying to figure out how to make the outside temp display work. I have gone to Nissan and they have told me it is not equipped. The display is there I just need help figuring out how to turn it on, because currently it is off and no temperature is showing. What can i do?
