TPMS light went on, but there's plenty of air in tire
This morning the TPMS light came on. I checked all 4 tires, but the psi was right where it always is. So I bet it's the spare. I wasn't dressed to get under and check, but I'm going to do it tonight. If that is the problem, do I have to reset the light in some way or will it just go off?

It will just go off if it's the spare. No need to reset.
|
my light always goes on in the winter. those things suck

i took mine out completly. the one in my spare was always leaking and setting off the light
|
It was just the spare. It had gone down to 20 psi
|
its funny, i have the 4 stock tires in my uninsulated garage, i park right outside, so theres not that much difference in temp, & yet its the spare on the vec. that gets low & sets it off.
|
this feature annoys the heck out of me, but I learned to live with it....

Fill the tires with Nitrogen, you won't have nearly the issue, especially with the spare.

Thanks for the tip here guys. TPMS came on when I left the ski area today. Came home aired up all four tires, stayed on...then came home and got on here and found this. :) Went back aired up the spare and it went off. What a goofy place to put a TPMS sensor, in the spare?
|
Eh, its not as goofy as you would think...
Most people never check their spare tires and those things rarely if ever get used... Think of it this way, you blow a tire on the highway and the spare you just put on is as flat as your damaged tire? I'm still surprised by the number of customer's who's spare tires are practically flat... |
What surprises me is that the spare loses air faster than those on the ground.
thinking about it: Probably because my spare is 3 times older than any of those on the ground. (its the original and never been used) |
I like it. I would rather be informed that my spare is near flat than try to use it one day, and it is dead.
Which has happened. People ignore the spare until they need it and they go "crap, it is flat too"! |
My TPMS light is activated and has been since I bought it 2 months ago. The guy who I bought it from said it was a faulty sensor in one of the wheels. However, I think I'll first check the spare. Never thought about that. However, he did take it to a Toyota dealership so...It would be funny if they got it wrong.

I wish there was some mod to bypass the spare.. I can't stuff a 33 in there so the spare sits in the garage, and I hate seeing the light. I wish it would take readings from all the other tires and ignore the missing spare. how does the sensor work, anyways? does it go off tire weight or something? I'd like to try and figure out some solution, seeing as how it hasn't been done. and btw, I also recommend nitrogen, im going on 14 months with no PSI loss in any tire.
