External temperature off
I have noticed the past couple days that it has been hot here in Texas, the external temperature reading in my truck was 5-7 degrees hotter than what I find from 3 other sources. The three other sources are within 2 degrees of eachother.
So, I am just curious if anybody else has noticed this? Is there any adjustment that can be made? Where and how are the temperature readings taken?
My truck is black, so depending on where the sensor is, not sure if that does or doesn't matter. I also realize the 3 other sources could be taking their temperature readings from a different place in town where the temp might be different than where I am. Just not sure if it is coincidence that my truck always shows 5-7 degrees high.

(in the Sonoran desert, two states west of you)My '05 used to read a little high when left in the sun too. Usually by only a few degrees, but every once in a while that one would be high by 10/12F for whatever reason. Metallic silver on both, so it's not just your black paint.

I know it will show high when first started, or after sitting for a while. Mine is still showing 5-7 high when I pull into the driveway after 25 minutes on the freeway/frontage road.
I know it's probably not a big deal, I blame it on me being an engineer, way too **** about everything.

Wow, not anywhere near where I would have guessed. Thanks for the info!

I thought the sensor was in the passenger mirror. There is a small access panel on the bottom of the mirror housing with the sensor connected to it.

I tested mine yesterday with a digital thermometer. The actual air temp at my house was 99 (shaded area in my yard), but the truck display read 108 over the hot driveway. I hung a thermometer on the passenger side mirror. It read 108.3. That tells me the gauges are right on.

Havn't noticed much discrepancy but it could be a couple of degrees off...
Where I had the problem was in the cold - I noticed that the really cold south Tx mornings 20-25° (That's Cold Here for you northerners) The temp would show correctly but 2-4 hours later when it would be warmed up in the 50's or 60's my screen would still say 25° even after restarts & sitting in the sun while off....
At some point it would all start working again.....
Anyway, I attributed it to being a Texas truck & like me - the cold freaks it out... I still threaten to move to Mexico every winter...
