    Default Outside Temp display gone mad

    I'm getting readings below absolute zero all of a sudden. The display will sit on some negative number, like -873 deg F, then it will step up to zero in increments, then plunge back to seriously cold (except its NC hot outside). Is this the sensor gone bad, and if so, where is it located? Mr Bentley doesn't seem to say much on this topic. All other OBC functions seem fine.

    You likely have some water in the harness plug. The harness plug is right behind the temp sensor. Unplug it and blow the water out. Sometimes takes a day or two to recover.

    A small plastic panel with a "hole" in it next to the driver's side foglight. You'll see the sensor pointing throught the hole.

    Thanks Jon. It is possible some coolant got into the harness plug. I was fooling around changing the coolant, and had a leaking radiator plug temporarily until I discovered the old gasket had stuck to the radiator, and it just didn't like having two gaskets. I'll look into it.

    Thanks Ryan. I didn't see your post until this morning when I noticed George's comment. Sorry. As I was driving to a seminar last night (before I could investigate further) the temp display began reading normally again. Looks like the harness connector is the place to begin looking when this happens. Johan's pics were interesting. I'll take a closer look later today.
