The low tire presure sensor light is blinking?

The low tire presure sensor light is blinking on my 2007 Tundra? I checked the presure and all 5 tires are good.
The owners manuel only says to take to the dealer.

 

Most likely the batteries in the sensors. They average around 10 years of life.

 

Thanks!

 

yeah, I agree to the previous post on the batteries in the TPMS. If you do end up needing new ones, I got Discount Tires to price match the Amazon ones for $20 each. However, that is usually when I got a new set of wheels and tires with them, but it's worth a try to ask.

1 or more of your TPMS sensors are bad. You can go to any tire shop and they’ll replace the sensor(s) that are bad. Probably $75-$100 each out the door. Or if you’re due for new tires soon you can just put black tape over that light and replace the sensors at that time.

I just bought these for my 07 a couple of weeks ago. They’re made by TRW, the OEM maker of our tpms sensors. If you look up OEM Toyota sensors, TRW is printed on them. $39 each and Sam’s club was able to install and program them. Fwiw, I had bought Denso Tpms sensors for my 06 Prius, and neither Sam’s nor a local tire shop could program them. The Dealer ended up having to do it, and even then it was tricky for them. Knowing this, I asked for recommendations on which sensors to buy for my Tundra. They said they’ve always been able to program OEM with no issues, other aftermarket brands are hit or miss for some reason.

 

costco is/was $65 each tpms installed. cheapest i found calling around. I still had the flash after i replaced all my tpms on the tires.

theres also a tpms signal sender under your headliner part is 89760-0c010 or 89760-0c020. They are super expensive but turns out you can get one from 2011-2015 sienna. 89760-08020 you just swap out the electronics in the box with your factory box and reinstall it. takes two torx screws to open it up. super easy and found one on ebay for $30 shipped.

 

Can the TPMS batteries be replaced? Does anyone have a picture of the TPMS unit used in the 2011 Tundra Crewmax 5.7?

 

i believe they are sealed units.

 

The batteries cannot be replaced

 

A little piece of black tape to cover that light works wonders! That whole system is a scam.

 

I think between replacing the tpms and the receiver it will fix over 98% of the people who ever got a tire pressure light. swapping out the receiver was only figured out in the last year on a different forum and i shared it on here.

 

shared it where? I would like to read more about this swapping out the receiver. Do you have the original post from who figured it out?

Mine is doing the same thing, I am just waiting until I replace the tires and I am going to put new sensors on all four tires.

 

I had this issue as well. Solving the mystery highlighted the value of these user forums for me. Prior to finding the solution, the pros at Costco and Toyota service were not able to even diagnose the problem in repeated efforts.

Since it has been warmer for the last two days, my light has gone off. Seems like the colder weather was affecting it.

 

That’s strange that weather seemed to affect it in that manner.

I had similar in my daily a Kia Sportage and the dealer just had to reset the system

 

Mine will start blinking from time to time. Always when single digits, but not consistently, and for a few minutes at a time.

I figure the battery in one of the pressure sensors is iffy and drops below the threshold for the indicator light when really cold.

Plan is to replace them all when I get my tires replaced. I'll just have to remember to have the spare done
