Question about 1999 Dodge Ram 2500 4WD
If the compass is working and the thermometer is stuck (or wrong), it probably a bad sender which is located behind the bumper on the driver's side bolted to the radiator support.
If the compass is not responding, it will probably need to be recalibrated and might need to reset the VAR. You can try to recalibrate first but if you have the owner's manual handy, go ahead and do the whole thing.
In the owner's manual there is a VAR (variation) code to tell the truck which part of the planet you're in so it will be accurate. Locate that code and then do the following:
To reset the variation:
1. Ignition on.
2. Hold down both buttons (US/Metric and Comp/temp) until VAR appears. (about 5 seconds)
3. Release both buttons. VAR remains.
4. Press and release the US/metric button. VAR1 appears. Press and release the US/metric button until the correct VAR is shown.
5. Press the Comp/temp button to store the new variation.
1. Start the engine.
2. Depress both buttons until CAL appears, about 5 seconds after VAR.
3. Release both buttons.
4. Drive the vehicle on a level surface, away from large metal objects, through three or more complete circles in less than 48 seconds. The CAL message will disappear from the display to indicate that the compass is now calibrated.

I had the same code on my 2001 dodge 2500. The truck wouldn't shift from 3-4. I pulled the trans pan off and replaced a broken spring ($2.00). It is behind a thin plate with 3-4 small torq screws. You don't have to remove the valvebody. Only took me 45 minutes to fix.
I would like to give thanks to Jeff Russel from Teal automotive. He said this is a very common problem. He sells any part for any automatic Transmision and his prices are very affordable.
Here is a link to the website.
Hope this helps.

your code is PCM/ECM power input signal intermittent. this is ussually a sign of a bad connection whether it be in a connector or a short or brake in a wire.
