RonMaiden Mine has been reasonably accurate for the area I'm in but of course it isn't going to match a weather report since it's the temp of the immediate vicinity of your vehicle.

smakin Mine is out more that 15 degrees Celsius. Is there any chance that this sensor / information is used for anything else in the car? temperature of intake air?

It is a little sad to know that something that should be so easy to make work somewhat well isn't. The "who cares?" attitude about this doesn't reflect well on the rest of things.

This.

I have never really found car temp sensors to be accurate because depending on where they place the sensor it can be affected by sunlight, shade, or in the case of older vehicles, engine heat, etc.

Let us know how things go at the dealership, bwolper. I'm also happy to check out ways to assist, just send me a PM with your information and I'll get to work. Please be sure to include your VIN, dealer, mileage, daytime phone number, and full name.

Thanks!

amc49 Yes, ten a bit much. I used to have one car ages ago with a $5 gimmick plastic clunky thermo that actually was pretty dang close and for the long term. Not like it's not doable. It finally caved in from slow melting after several Texas summers. First time I ever realized it can hit 140F in a car interior.

a_2000_se Anyone happen to catch the story recently about next gen smart cars in the not too distant future that will collect weather data and transmit that to roadside towers along with embedded sensors. Then to a data center that processes the information and sends it back to drivers warning them of black ice/fog and other current/pending weather conditions. The story mentioned weather is the main cause of vehicle accidents and death. It was relating to that 75 car pile-up in recently in Virgina due to fog.

I don't know about you but distractions have to be catching up with weather. Grandma and grandpa are overwhelmed with every new car purchase.

amc49 Yep. Weather channel rules. It wouldn't matter one whit if the gauge is within 2 degrees, ice forms at 32 and not 33 but at the measured LOCAL SPOT only. Here in Texas ice can be on overpasses with wind and 34 temp listed on anything you want to read. Meaning something like wind chill going on there. Temperature can vary up to 5 degrees easily just depending on where you are in the city, the northern reaches of Fort worth here always have plenty of accidents because flat and not much building there to break the wind. Elsewhere in city no ice at all but same temp everywhere there, just local spots vary. Common, the outlying regions get worse because less concrete to radiate heat and less traffic to keep condensation scrubbed off overpasses and outer highways. Concreted areas can be 33 at the surface and the air 12 inches higher above is 25, dead accurate gauge will not help you there.

Car temp gauges are absolutely worthless for determination of road condition. So is a single weather report. One learns to use EVERYTHING to determine that, meaning look at the cold front on the weather for effects in other states before it gets to you, you can tell pretty much how much trouble you will have. NOAA invaluable for that. That plus your realtime temp and wind, plus listening to traffic data, plus time the ground has been above or below freezing point, and you can make a pretty much bulletproof guess on what the driving conditions are.

That someone would seriously consider dumping a car over a temp gauge, well, I won't say what I think about that. If that important, I certainly would be looking for a stand alone certified scientific measuring instrument instead of relying on junk.
