Outside temp wrong
I tried to search and failed, anywho, my outside temp constantly reads 20-25* cool. I remember reading something about cleaning it, and I found it I think (blue/black plug in front of the engine), however don't remember how/what to clean. Thanks for the assistance.

Does your A/C work? If not, outside temp sensor, #10248401, could be bad. Check DIC for code: DTC 99-B0333 (Open)
Mine went bad and registered 32° and A/C wouldn't come on. $13 at the dealer.

I doubt you're looking in the right place if you're looking around the engine. The sensor is on the passenger side of the housing bringing air into the front of the radiator down near the bottom. It's on the outside of the plastic with the probe tip sticking into the air flow. You'd see the black platic tip if you are looking into the rad opening.

I have a 99 and have the same problem, except only about 7 degrees colder than actual air temp.
I am glad I stumbled across this thread. I just bought the car a couple of months ago and hadn't gotten around to investigating it yet. This gives me some good things to look at and that it sounds like an easy cheap fix. (that never happens for me).
Did that part number apply to all years of C5's?
What year car does the OP have?
I am trying to find out how similar mine is to the posts in this thread.
Thanks

OK, so I changed my sensor & checked the wiring...still reads 66*. Is there a fuse/reset for this or something else I'm missing? Oh yeah outside temp is currently 81* so I know it's wrong, thanks.

I fought this on my 99 for a while. I had a bad sensor and a corroded female connector. Grounds may have been corroded so i cleaned them also. After getting these right, it took about 20 min of driving to relearn to get the correct OAT.
