Time to Outside Temperature Reading?
On my C6, it seems to take about 15 minutes or so after starting to get a reading on the outside temperature. That doesn't seem right to me ... think I have a bad sensor?
Thanks!
Thanks!

It has a built in delay to make sure that the temp that it displays is more accurate. They talk about that in the manual.

I've had this problem from day 1! I think it's stupid. All of my other cars work just fine.
Here is what I found on GM's Corvette Action Center.

Guess we'll have to live with it.
To me, this sounds like Engineer gibberish meaning "we can't figure out how to make it work" so we'll say that's what it's supposed to do.

If the outside temperature goes up, the displayed
temperature will not change until:
• The vehicle’s speed is above 10 mph (16 km/h)
five minutes.
• The vehicle’s speed is above 32 mph (52 km/h) for
two and a half minutes.
These delays prevent false readings. If the temperature
goes down, the outside temperature will be shown
when you start the vehicle. If it has been turned off for
less than three hours, the temperature will be recalled
from the previous vehicle operation.

I have noticed the delay too. I have also noticed that the climate control works very well. I have had cars where the climate control got a little over aggressive in trying change the temperature.

I had an '88 before they changed this algorithm, and it was useless. Whenever you stopped at a light, the heat from the road and underhood would raise the reading. On an 80 deg day, it would read 120 or so while waiting for the light to change, then it would go back down. The way it works now is fine. BTW - my Jaguar takes even longer to read properly.

Does the outside temp sensor reading affect the HVAC settings in auto mode? I had the outside temp go up to 75* the other day (it was 53* when I shut the car off in the the morning) and the auto mode started blowing warm air into the cabin until the outside temp sensor corrected itself and cuaght up to teh actual outside temp.

. There is a sensor that looks at outside sun loading, though.

Mine appears to be pretty accurate for what the garage should be when I get in it and very quickly goes to what seems to be the proper temp. In heavy traffic, 80plus degree Fl. heat it still reads as it should and doesn't jump higher more than a few degrees. So far I haven't seen it over 87 which was probably 83 real degrees in heavy traffic.
