Hi EBEAVERS01,
BASSTECH is correct about the system not telling you which tire is low. It's purpose is to give you the warning so you can have time to slowdown and stop before the tire is so low that it can cause a hazardous situation. I'd venture a guess that most of the times that the warning comes "ON", that it's not a fast leak problem, but I personally had a situation where, after I had run over a metal object on the highway, the warning came on and I was able
to get the car off the highway and stopped before the tire went flat.
The system will not automatically reset itself. You, or someone, will have to reset it. The first thing you need to do is service the tires to the recommended pressure. Then perform the TIRE MONITOR RESET PROCEDURE that is in the Owner's Manual.
If you can't find it in the Owner's Manual, let me know, and I'll find it for you.

Additional Info:
I had a few minutes to think about the Reset Procedure. I posted it to another Impala owner a few days ago.
Look at page 3 of the posts about 6 posts from the top of the page. Look for "2002 Chevy Impala Message Board Error" posted by will1464. In my reply to will1464, I gave him the Reset Procedure from the Owner's Manual.
