Ambient Temperature Sensor

[2002pirate]

My 2002 Compass/ ambient thermometer started reading 140F. I put 3 sensors in it and disconnected
the battery the last 2 times. Same result. The dealer can't even fix it.
Any help out there??
Thanks,
Billy

Billy,

Is the compass function operating normally?

Maybe he's reading degrees azimuth!
(I believe that's southeast)

Yes the compass functions normal.

One of two three things have failed:

Sensor-located in front grill area. Previously replaced 3 times. Rule this one out.

Wiring between the two. Since this has been in the shop for at least one effort--probably not the issue.

Display/computer-this is the expensive one--is yours in the dash or do you have an Overhead Trip Information System (OTIS)? One is much more than the other.

The 2002 I have only the compass and Ambient Temperature in F&C are available.
A couple of the sensors I tried offered an new temp of -33F instead of only140f or 40C. That is the only change I saw. The compass has always been correct. I'm thinking that it maybe a file in the computer? I'm all with the idea that it's the wires in between. But all the temp readings wew exact or close. The one reading I got at-33f came up to 140 in a short drive. I'm thinking of pulling fuses one at a time and trying to get a reset.

move to Iraq or Alaska...

Then the temps will be closer to what it's displaying... LOL

I swore I read in the owners manual about resetting the temp? Mine started saying I was always going south... I had to drive in circles for a minute to calibrate it... There's got to be a easy thing being overlooked... I'd hate to think it is one of the more expensive ones that were mentioned above...
