every morning on my way to work after about 10 minutes the orange warning light comes on and "psi" flashes on digital reader. The readings average from 28 to 31 psi. But the weird thing about it is it goes off later on in the day and the readings go back to being all above 30psi. I took it to the dealer but he told me to bring it back when the light was on. Anyone else have this problem?? Input would be appreciated.

 

30psi is low...

hows your gas mileage?
tirewear?

put some air in those

 

you should figure out what the real tire pressure is with a reliable tire pressure guage and then decide if it's your psi or if its TPS system thats the problem

 

it happens to me in humid climates and cold weather. It just needs some more air. Try to keep it above 32psi.

 

When the light comes on it gives me figures ranging from 28 to 31 psi. I think thats inaccurate though because after a while it will return to readings between 32 and 34 and the light will go off. I know the tires arent inflating themselves so i think its the sensors. i have about 14xxx miles and my tire tread is maybe like 70%. But ill put some air it in and go buy an electronic tp meter to see for myself whats up.
