I have had a problem with my overhead compass temp gauge. I replaced it with the same year one because my map lights were broken plus the temp has always been OD or it will say -135* or 118* or always way off and even with the old overhead gauge it did it and when I put the other one in it has also done this anyone have any ideas???

I think you meant to type "OC", not "OD". OC would be an indicator for "open circuit"

I think you are right I will look today what does it mean by open circuit? wires loose??

Easy way out would be that the sensor is "open". If not, could be a wiring prob. With the sensor unplugged the overhead should read "oc". Jump the connector and it should read "SC" for short circuit. Thats a quickie way to check the wiring and possibly determine that you have a sensor prob.

where is the sensor on these things 1997? is it under the hood?

The sensor on my '96 was on the lower driver side radiator support. My '02 is behind the grill. Not sure when they changed.
Check the sensor resistance. Manual says 336kohms @ -40*C and 2.4kohms @ 55*C. If you need a replacement from a junk yard any DC vehicle should do.

can anyone help with a picture or diagram I can't seem to find the sensor??
