Outside Air Temp Sensor

2004 SCREW 4x4 52k

I just got back from a Seattle to Salt Lake City Ski trip and the Temp is suddenly reading way high - 30 to 50 degrees above ambient.

This morning I was scraping ice and the temp at startup read 84. by the time I got to work (9miles) I had 71 deg. The indication is erratic sometimes it increases while driving, sometimes it decreases. I am guessing either loose or corroded connection at the sensor or a bad sensor. several questions,

Where is the sensor ?

Should I attempt replacement or go for Dealer assist ?

I read through a number of threads, some referred to re flashing after sensor replacement which means a trip to the dealer...... is re flash necessary ?

Advice ?????????

Mine is right in front of the radiator, just behind the grille. It's only accurate when you're moving down the road from what I've seen.

they are very easy to replace.... just have a screw holding them to the radiator support, and a wire plug.... it is directly in front of the radiator, on a verticle mount.... but there are 2 sensors there.... the lower one is for the airbags, and the upper is for the temp. it has a kinda "cone" shape end on it.

ya mine did that before when i first bought the truck i took it to them cause it was 90 at 20 degrees outside and sometimes it said -45 well I took it in and they said they would fix it and got it back and they told me 80 for it they took it down from I think it was a 100 this was a few months ago I told them to take it off but they wouldnt so I had to pay for it. I wasnt a happy camper there.
