How accurate is the Tc's outside temperature reading?
Anyone have the theory of the car sitting on hot asphalt?? Would that be where the deviation in actual temperature is coming from.
The temp guage should be an actual probe on the car somewhere. now as for finding it...

Open the hood, to the left side looking down at the radiator, in front of it is the AC purge valve and a control valve it appears, the temp sensor is mounted to the front of that unit.

I have one of those too
It reads high when you first turn the car on cause its been sitting and your engine compartment is all metal so its like an oven. Once you get going its pretty accurate. Driving in the middle of wide roads in the sun seems to add a few to it. Maybe 2 to 5 degrees high but plenty close.
After moving north, I have found how much I miss thoses 100 degree days! It is nice to have a milder summer, but I also wish it would get a little blistery once in a while here. But, it is fun to hear people here in MN talk about how hot 92 - 93 degrees is

And the temp gauge isn't off only in the summer.
January in North Dakota, mine read 55 out...it was warm, but not that warm, settled down to a nice 28

Draven, you musta been in the Duluth area for that temp!!! That is just colder than hell!

Of course, Vegas isn't exempt either...
