Outside Temperature Gauge sensor......where is it located?

[wngrog]

I recently went to Big Bend in the heat of the summer and was amazed at the temperatures I saw in the desert. I had a thermometer with me (meat thermometer.....don't ask) but when I stopped I would carry it outside and it would register the same as the truck was registering

Where is that sensor on these trucks?

I have a 1998 ......

I think it's IAT (Intake Air Temperature)

I've been to Bibe in the summer more times than I can remember. I've never seen the thermometer read that high unless the vehicle has just been started.

I was down on the river and the WeatherUnderground projected temps that day were 105 so in the direct sun, it makes sense that it was 120

OAT sensor, iirc, is behind the grill.

Here's the sensor on my '03...in the center of the picture, just above the passenger side frame rail, behind the grill as @hankinid mentioned.

Cool thanks. It's amazingly accurate. I guess since the fan pulls the engine heat away....

Its, IMHO, a stupid location for ambient temp sensor. Generally if < ~20mph, all things trail work, the temp skews high (due to engine heat pushing on it)...pointless. Some 80-Series guys relocate the sensor to the interior of the snorkel...if so equipped, then no hot engine impart

I honestly never thought much about it until I went to Big Bend alone in July.

I started watching it like a hawk. I thought it was the black ball on the dash but I ruled that out

One of the dash sensors sees light or darkness and works with the automatic headlight system. The other senses temp and works with the heater/ac systems.

Good to know. I tossed a wet rag on one to see what happened. That's when I figured it out.
