The light came on, I went and put air in the tires. Started up the truck and the warning light came back on. Don't know why.

You have to drive for it to go off sometimes.

Oldsmuggler

Takes a little time..it will go off.

Could also be that the spare tire is low?

CollinM

No. Spare tire does not have a sensor

Steve Osborne

did you put enough air in?...35psi for most or 40 on others...check your door tag for recommended psi...

RES4CUE

Is it saying low air pressure or tire pressure sensor fault?

One is just low air and needs to be above a certain psi, it will ay in manual.

The other means it is shot and needs replaced and won't go out until you replace it.

This and you need to drive for a couple of minutes. Something about the movement "waking up" the sensors.

Mine came on 2 days ago aswell and I couldn't figure out why until I realized that the colder weather makes the air pressure decrease. Decrease in temp- Air press decreases
Increase in temp- Air press increases

I was able to fix mine by letting tires all the way down before airing them up. My brother said he read that somewhere, so we tried it.
