Tire pressure light

My tire pressure light just came on, thought I might have a tire starting to go down, like last time.
However after checking the pressures. everything is at 29lbs . Does anyone know where that sensor is and is there any way of resetting it? Thanks.

Did you check your spare?

 

^^^yep, thats probably what it is.

 

BTW...the sensors are part of your valve stem in each of the 5 tires...

 

'cept for the 09's that have only 4 no sensor in the spare.

Jeff, when you check it, flip it over, makes checking it next time a breeze!

 

Same thing happened to me today... fired the truck up to go to work, tire pressure light is on. Checked tires, all at 30psi - is it possible that the light comes on when the temperature gets too low and they are over 29?

 

yes that happened to me checked all tires and the spare i just needed to drive warm them tires then went off.

 

Not if they are filled with nitrogen gas

 

Definately the spare. It happened to me last winter about 2 miles down the highway. I pulled over asap expecting to find a tire losing air. It was only later in the day I remembered the spare which was down to 26PSI when I checked it that night.

 

Toyota has a new T-SB for cold weather tire pressure compensation adjustment.
