TPMS indicator won't shut off

So my TPMS went off last night so today I checked and the tires which all read 34 Psi except for the spare which read 20. So I put the spare to 34 and reinstalled it (separate issue but now I can't get the spare to stay up it keeps lowering every few miles...driving me F..ing nuts). I went to the manual and found that to be useless cause everything it told me to do did not reset the indicator light. Any suggestions...Please

 

Did you have any work done to the tires recently, new tires?

 

My 2008 required a solid 30mins after topping up all tires to 34psi before it would go out...

Later down the road my tpms module (somewhere behind the climate controls) decided to throw in the towel... I couldn't justify the $ they wanted to replace it and reprogram the sensors, so I put up with the light... Hope your issue turns out to be cheaper than what mine turned out to be.

 

It took two days for the TPMS light to come on after I changed to TRD Pro rims, new TPMS modules which are supposedly correct for those rims - and Toyo ATII's.....P265/70R17.

Give it some time...it will eventually let you down.

 

No I haven't done anything to it other than installing a shell about a week and a half ago. The tires have been on there for eight thousand miles.

 

I never could get mine to go off. Finally had to replace the tires and rebuild the TPMS Sensors.

You may need to have sensors rebuilt. Or just get used the the TPMS light.
I actually had to get used to NOT seeing it on once it was fixed.

 

Did you try pressing the set button?

 

Assuming you did hold down the reset button (under the steering column), but I would also suggest disconnecting the battery for 30 minutes too.

Since you have a '12, I doubt the battery in your sensor is dead.

 

You may also try disconnecting the vehicle battery for about 10 minutes. That worked on my sons 2008 taco after adding air to the spare.

EDIT: Ben was faster than me by a minute...lol!! Great minds ya know.
