Dashboard tire warning light

How do I go about resetting the tire warning light? All the tires are to spec and I've tried to reset the warning light more than once, but with no luck

 

How old are the tire sensors? One of them could be bad.

 

If it's a 2012, the batteries are likely dead. They usually last about 7 years ish? Give or take a few.

 

Did you air up the spare too?

sometimes they have TPMS as well.

 

2012 didn't come stock with a spare TPMS...

 

Is the light blinking or solid?

Solid is low air pressure.

Light that flashes for 60-90 seconds and then illuminates solid is signaling that there is a problem with the TPMS system.

Flashing light can mean the sensor is damaged, missing, or has a dead battery and needs to be replaced.

 

When the batteries die just buy a $5 tire gauge and save yourself the added grief and thousands of dollars these $@#*&%$!! sensors are going to cost you over the life of the truck.... i'n still waiting for my *^$#&!! tpms dash light to burn out.

 

To turn the light off just snip the wire, it'll never bother you again. Another great government intervention such as sealed gas tanks!

 

Something else to consider is it may not be a sensor. The sensors are the most likely issue but there's a chance it may have something to do with the computer itself. My GMC Canyon had a perpetual TPMS warning light throughout the 4 years I owned it. The dealership replaced a sensor and that fixed it for a couple of weeks but once it came back it never went away after that. I had several tire shops attempt to fix it, including replacing "dead" sensors but they all came to the conclusion they couldn't fix it and I would need to go to a GM dealership to actually get it fixed.

I even tried myself, using the owner's manual method which involved the horn honking to acknowledge it recognized the tire sensor. Even still, it never went away and since the truck was 8 years old when I purchased it, I didn't think it worth pouring the money into over TPMS.

 

Awesome guys. Thanks for the info. Mine blinks and then stays solid. I'm going with the "use the tire gauge" method and going to forget about the warning light on the dashboard.

 

TPMS light came on (tires were low, so I inflated all tires to 29PSI as per door sticker)
Tried TPMS reset (several times following manual and above procedure)
Light stayed on

Was going for short drive so I tried again with a change
Had truck running
Reset TPMS
Drove truck about 10 minutes at city speeds c/w stops at traffic lights
Shut truck off to pick up my parcel
Came out started truck
Light went out

Sorry didn't notice if light had gone out while driving

Hopefully this may help someone else

 

29PSI is that what the sticker says, jeepers . . .

 

Just remember... don't look into the light!!

 

Dang, what a silly procedure. Did it say to pat your head and rub your tummy at the same time too?

 

Yeah, right after making a sacrifice while standing on one leg lol.

Basically it involved raising or lowering the tire pressure in each tire in a certain order until the truck honked acknowledging it recognized the sensor. Yes, it was annoying.

 

I'm a cheap SOB. I raided my wife's sewing closet and cut some black felt to fit in the bottom of the dash to hide the blinking light.

 

Was in getting an oil change yesterday and a customer was discussing his tire pressure sensors.

His vehicle was an 09

$55 per sensor, plus $20 to install…… yep…… $75 each

 

TPM system has to work in Vermont to pass annual safety inspection. Gets really costly as some brands of vehicles seem impossible to fix. They do a code scan as part of the inspection. The scanner they use for inspection is part of a statewide network so once your vehicle fails for any reason it is failed network wide. You can't go to another inspection station as your vehicle is flagged as failed. The state did make an exception for emission related check engine lights for vehicles over 15 years old. The state finally realized it would cost more than the vehicles are worth to fix.

 

I replaced all 4 sensors in my 2012. I went from the stock steel wheels to Level 8 Mk6 wheels (the steel wheel sensors have a different angle than the alum. ones).
I used all new sensors bought from Toyota. The new sensors look like they were updated with a bigger battery.

 

The batteries typically last 8-10 years, but sometimes longer. It's no big deal to replace them. It won't cost you thousands of dollars.

I paid $80 for a set of 4. These fit your truck. I've replaced sensors in 3 vehicles over the years with these and all worked just fine. If they last you ten years that works out to about the same cost as one McDonalds value meal a year.

It is best to have them replaced when mounting new tires. If you are close to needing new tires I'd buy a set and take them to the tire store when having new tires mounted. No shop will charge you any extra at that time. If they have to break down tires and replace them expect to pay $10-$20 per tire for installation.


TPMS doesn't replace an air gauge. What they do is monitor air pressure while you're driving and warns you of a sudden tire deflation. Twice in the last 10 years I've ran over road debris and punctured a significant hole in tires. The warning light gave me just enough time to get to the shoulder of the road and stopped before the tire went completely flat. Having a tire come apart at 75 mph isn't something I want to experience. Having to pay $80 every 10 years to prevent it is money well spent.
