Well when you say you just replaced long ago? I have heard it can take a few days before the temperature reads correctly. Otherwise, it likely is a wiring problem...of course assuming your tempeature sensor is working. I would check that first....its located behind the plastic door right next to the drivers side fog light.....its probably easier to get to it from the other side though.

I just replace my OBC with a used one. Everything seems to work except the temp. It constantly reads negative temp. It does fluctuate but always in the negative.

Do I need a new sensor? Where is it located?
