Since winter is over, I've recently put back my stock 18s on with the TPMS sensors. I've been driving with the tire pressure light on all this time with my winter wheel/tires.

Great! No more light! Or so I thought...

I notice sometimes when I drive about 15-20 minutes, the light would blink, then stay steady. Then sometimes it would just out after another 20 minutes or so.

I keep all tires at around 33-34 psi. I'm still on the stock tires.

Any thoughts? The temps here in Chicago is about 50-70, so it's not like there's a huge temp difference (like 30 to 60).

Does the TPMS also trip when the pressure is too high?

Check you pressures again, mine did that on my 07 and 1 of the tires was low.
Or you have a sensor going out.

Before I went to the dealer, I checked my pressures, a?"nd they were spot on. They claimed that my tires were over inflated at 42 psi, even though before I left the house, they were all 32 psi all round. They claim to have reset the pressures to 32 psi all round.

I kept telling them that's weird, and if they were sure, because my pressures were right. They said it may be my gauge. So I said "You set it to 32 psi all round, right?" They said "yes". So I said "I got the gauge right here. Lets see" Sure enough, the tires say 32 psi all around. "It's not the gauge". They swore it was a 42 psi before.

Whatever... I drove back home, and the damn light started blinking then stayed on like it does. I called, and rescheduled another day to bring my car in.

It's getting stupid. I cant take any more days off for this.

I need to have mine turned off since I don't have the sensors in my wheels, I would say it is a bad Sensor though.
