I just noticed the other day that my 2005 Lariat has the outside temp stuck at 140 degrees. I have tried disconnecting the battery but it still shows up. Anyone else have or seen this issue before I take it in?

Thanks!

 

I'd hate to live where you are. I can't stand it much above 75.

 

Gonna guess bad sender, or loose connection. Well, a dealer probem if there ever was one.
Weird one though.

ever lay your hand on your hood after its been in Sun all afternoon. I'd bet its 140+ So unless its always 140 maybe its just from the baking?????

 

Sometimes I've wondered about mine - it will get as high as 125 even though I know there's no way that can be true - if you find out what it is, please let me know since mine is no longer under warranty!

 

Mine's similar except it seems to be 2 degrees (C) too cold. Thats according to all of those electronic billboards anyways.

 

Mine has sat in the sun in 115+ heat all day and doesn't read more than about 120. I don't think that's his problem.

 

It is 140 degrees all the time when it has been in the 80s lately. Now it is reading --- degrees. I am taking it in since I don't know where the sensor is to check for a bad connection.

 

Hmmm...
I have a theory, instead of the cruise control wiring starting fires as in the previous generations of F-150s, the engineers decided to move the problem to the ambient air temperature sensor.

The reading you are seeing is the beginning of a fire!!!!































OK, maybe not

 

I had to have my sending unit replaced, it was doing the opposite, always reading colder than it was outside.

 

The sensor is mounted on the support that runs right up the middle of the radiator.

 

DAMN it's hot in Cali fry! Bring that beast (and car) up to Oregon, they'll love it up here.

 

LMAO! I haven't taken the time to try to find the sensor or stop by the dealer yet. The outside temp display doesn't bother me as much as the Interior Temp Control isn't working because of it...

 

I want to say there may be an updated PCM calibration that fixes this, but it could be a faulty ambient temp sensor as well. Our '05 Expedition is bass-ackwards of your truck; every now and then, it'll read like -40 degrees F.

 

It might be either... I am going to pick up a new sensor today to see if that fixes things. Just yesterday, it started to work again. Then I washed the truck and back to --- it goes. Since last night, it works sometimes and sometimes it displays ---. Go figure!
