TPMS light is on...

[rrod436]

the other day when we got our first freeze, I went out to go to work, turned on the car and the TPMS light went on. I thought it was due to the rapid cooling from the night before and the trip to work would warm them and all would be ok. Not so. today I finally got a chance to go outside and I checked all the tires and adjusted one or tow of them to 30# psi. I did this while the tires were cold. I turned on the car and the light is still on. What am I doing wrong, or there a reset. I don't have the EVIC.

I guess there's a chance that one of your batteries is dead/dying, but it seems early for that. So they're all whatever pressure your door jamb recommends?

What tire pressure do you normally drive on? I've heard that all sensors should be above 35lbs. to keep that light off !? It also takes a few minutes for the PCM resets the new pressures. How much time did you give before getting concern?

[rrod436]

All at 30#, as per door jamb. I drove for 15 min. and the light went out. I guess that is the reset?

Yeah, they don't turn on until the wheels start rolling and then the car ignores them for a certain amount of time until it figures they're on and functioning and the tires are warm.
