I believe that the sensor is in the valve. Here's a snippet from a Toyota bulletin regarding a change to the 2009 Tacoma spare tire:
"11. Tire Pressure Warning System
The tire pressure warning valve and transmitter has been discontinued on the spare tire. Alternatively, an
information label indicating “TEMPORARY USE ONLY” has been placed on the spare tire disc wheel.
The spare tire for the ’09 Toyota Tacoma is only for temporary use. Do not perform tire rotations on
the spare tire."
So I could see how adding some Fix-a-Flat could gunk up the valve/transmitter.
For the guy who bought the new aluminum wheels, could you take your old valve assemblies and put them on your new wheels? Just a thought.
My 2008 Tacoma will definitely set off the low tire pressue light when the spare gets too low. Airing it up will shut the light off. The valve sensors do seem to work well. I hope I can make the same statement when my truck gets 10-12 years on it!

hi mr buffalonickle, i solved the problem. When i took my tachoma in for service at the dealer i had them check all the tire sensors and they found one of the sensors which are attached to the tire valve stems damaged. The damage occurred when I purchased the new tires from kmart / sears. One of the services techs attempted to replace the valve stem and noticed there was a device (the sensor) attached to it. When attempting to replace the stem or replacing the tire on the rim the sensor was mortally wounded. I showed the manager at sears / kmart the damage they caused and they refunded me the cost of repairs. $248.

Cannot get the low pressure warning light to reset. I've insured all tires are the same pressure, followed the owners manual and NOTHING. Light will not go out. Any suggestions?

I have a 2007 Tacoma. Recently, the tire pressure warning light came on. I checked by tires and found them only 3-4 psi low. I corrected that and the light still stayed lit. Then, I lowered my spare and found it about 15 psi low. I corrected that and at first, the light stayed on but within a block of my home, the light went out and has not lit again. Hope this helps.

Hello doen anybody here know how to simply turn the tire pressure light off! I broke one of the sesors off roading and dont want to pay alot to replace it thank you

is it possible to just disconnect a wire somewhere to turn the light out on the tire pressure sensor. I really dont like this feature and can live without it. it is a stupid idea and I just want to know can I do something to get rid of the feature all togather.
#23 of 35 What should you set your tire pressure to??
Jul 13, 2010 (2:05 pm)
My husband and I have a 2010 Tacoma double cab. The tire pressure light was on when we test drove it. They put air in the tires when we bought it and it went off. Then, about a week later it came on again. My husband took it to the dealership, and they checked the spare and all the tires and inflated them more than PSI of 29 which is what the inside of the car door says to inflate them. They talked my husband into believing that it was okay to inflate them over the 29 PSI and said they do it all the time. He got angry later when he was thinking about it, because the recommended PSI is 29 on the door. He brought it back and they gave him a loaner car to drive the next day to check out the sensors. Again, they said they needed to inflate the tires to 35 PSI and that they called an expert on tires and thats what he said to do. So now the tires are inflated to 35 and the light doesnt come on.....but we are still wondering if this will wear out the tires sooner than normal and what the reasoning is that we can't inflate them to 29 like it says we are supposed to. Any ideas? Any anyone else told this story also?

I keep tire pressure at about 35 psi on my '08 4x4 Tacoma. Take a look at your tires and they'll have a maximum recommended pressure and a maximum recommended psi on the tire. I still have the original factory tires on my Tacoma and the low tire pressure light can come on annoyingly often when I run the tires at 30 psi. Different tire pressures provide different performance. If you like a soft ride and don't haul heavy loads (and assuming you don't have the tire pressure lights, which I HATE) I'd run my tires at about 25 psi. If hauling heavy loads like firewood, I pump the tires up to about 40 psi. The tires just perform better that way. I had a Ford F150 that I'd pump up to 44 psi for heavy loads but would run 32 psi for everyday driving. And if I wanted lots of traction in snow I'd drop to 25 psi.
Changing tire pressures up or down is commonly done on many types of vehicles. You'll hear people say "low pressure wears out tires, or high pressure wears out tires faster, but it's more complicated than that. If you haul a heavy load on lower than average pressures, you really wear your tires. If you run around all the time with 40 psi tires you'll have a bouncier ride and will wear your tires too.
Now to answer your question. You won't be able to tell any significant performance difference between 29 psi and 35 psi on your factory tires. You won't see any real difference in wear, either. Rotate your tires as recommended and you'll be fine. Pressurizing to 35 psi is a realistic and honest way for the dealer to deal with the tire pressure system hypersensitivity problem.
Other than the tire pressure system, I love my Tacoma. I use it on my farm and tow, haul, etc. It's a solid truck. Good luck with yours.

#26 of 35 Where is this sensor
Dec 11, 2010 (7:50 am)
Hi- I'm new to this forum and have seen a lot of discussion about the low tire pressure sensor. Can anyone tell me just where the sensor is in the spare tire? My husband thinks Toyota is telling a fib because, looking at the tire, he can't imagine where it could be.
