My 2005 Tundra has the stupid TPMS. When I bought the truck used (at CarMax), it was lit - the truck had only 18k miles. Toyota "fixed" it by replacing the one bad sensor but said when CarMax put the new (cheap) tires on it, they broke it. So I when back to CarMax and they covered the cost. Then another went out and they covered that.
Several years later, the light came back on. When I got a new set of tires, I told them to just put regular valve stems in. They said they were not allowed to do that. Now the sensors have replaceable batteries and whenever they replace the tires, they replace the battery.
My light stays on now...
I found a web site that shows where to disconnect the system and ground it out so it doesn't light up the light. Its behind the glove box.
To top it off, I have to instruct any shop (including tire stores) to NOT set the tire pressure to the door sticker. I run my tires at max pressure so they wear properly and because I actually use my truck to haul stuff.
Remember the Ford
Exploder a ways back? True story. We just bought a used 1998 Exploder. Had Firestone tires on it. Took it back to the dealer for something or other. The tires had a tire pressure printed of something like 36psi. The dealer dropped them down to the door sticker - 26psi. We took a long trip at highway speeds - but nothing bad happened. Then the news came out the following week about recalls due to the blowouts. Duh - under inflated tires! From that point on, I don't let anyone adjust my tires. And I only run Michelin now.
