So on my 2000 xj it has this thing on the roof that tells me my miles left on the tank, the mpg, and more. They all work except for the temperature outside. It always says 0°c. How do I fix it

 

Hmm. This may not be much help considering I have a 96 xj and don't have this luxury. My guess would be either a bad sensor that reads this temperature or a disconnected sensor. But I don't know where it would be located haha

 

Yea me either that's the problem Haha

 

It's located behind the bumper in the middle in front of the rad cradle.

 

Any idea of what it looks like?

 

I thought this was for tearing a hole in the space-time continuum, to let my Jeep slip forward.
