Tire Pressure Light....?

I just upgraded 3 months ago from an 01 to a 15. My tire pressure light came on. I found one tire at 30 where the rest were 44. I filled it up, but the light is still on. Is there a reset switch, or do i have a problem?

Thanks!

 

Did you check the spare?

 

Sometimes it takes a couple of miles of driving for it to go off. There is also a reset button under the dash. Your owner's manual will tell you how to use it.

 

the 2015 TPMS only monitors 4 sensors and cannot be modified to do 5. It’s possible that one of the 4 is the spare, but unlikely. This would only be the case if the original owner had matched the spare ( rim and tire type) to the others and had swapped its location.

 

WELCOME

 

Thanks guys! hope this problem solves itself.

 

PSI had been running around 45, now that the temps dropped my Low psi light came on. I wanted everyone to know what psi trigers the TPMS low tire pressure warning, answer it's below 41 psi. Tires are 285,55/20 BF Goodrich All terrain KO's. How much air is everyone running?

 

I think that's only if you have the pressure set to 45 as it's normal tire pressure. I know when I let the air out of mine down to 38 I had to reset it. It didn't go off again after that.

 

45 psi ?

 

35 or 38 I beleive

 

I didn't know you could set them, but makes since. Guess I may add some more air for winter time, who knows I may get some better gas milage.

 

Welcome from SE VA...

 

I just put all new sensors on my 08 Toyota tundra tire pressure light came back on a day later how do you determine which tire is low pressure

 

There is a "re-set" button located on the lower kick panel on the RH side...right below the trailer brake controller. Once you set your desired pressure, you need to turn the key on and press and hold this button until the low pressure light blinks 3 times. I can't remember if the key has to be in the ACC or ON position (check manual). Once reset, when the pressure drops by a predetermined amount (no idea what that is), it will notify you.

Good Luck!

 

Where did you get sensors, my dealership wants some supercilious amount for them or is tHere an aftermarket that works as well?

 

Does the tire pressure light blink a few times when you turn on your truck?
I also just got new sensors, but resetting didn’t work for me. Every time I turn my truck on it blinks a few times, I guess that means that I need to take it to the dealer so they can reprogram the new sensors I put in.
