After about 20 mins of driving my tire sensor light goes on. I have aftermarket rims and the tire pressure seems to be fine on all the tires. I wasnt even aware i had sensors on these rims, or on my previous 17' stock wheels for that matter. When i got a total flat one time, the yellow light didnt even go off. Is this a computer error that could be contributed to the dramatic drop in temperature?

That is normal behavior of the tire pressure monitoring system. Since your (aftermarket) rims do not have the tire pressure sensors, the computer is not getting any signals from them. After driving for a while, the computer turns on the low tire pressure light (without souding the alarm) to indicate there is a problem in the system.

Which rims did you have on the car when you had a flat?

2004.5 DG/G 5AT Coupe with all options
Sidemarker turnsignal mod
GroundingGear™
2003 Yamaha YZF600R

 

interesting. i had the aftermarket ones on when the tire blew awhile ago. How do i make it so the light wont come on?

You can either install TPS in your aftermarket rims (assuming they fit), remove that bulb (unlikely), or ignore it (most likely).
