I believe all cars produced for the US market had them as a required safety feature from the mid-2000's.
On the Patriots, there's two styles--one is just the warning light, the other uses EVIC and will display a picture of all 4 wheels with their pressures. (I wish it would also visualize the spare--you have to remove it to check its pressure...)
I jump on the occasion and ask you all: does anybody know a way to temporarily disable the TPMS ? I use a different set of wheels in winter, and they don't have the bloody sensors (which are pretty expensive, by the way).
depends.
do you have the evic full display or just the dash warning lamp
(I can t punctuate for some reason)
I put on winter rims with no TPMS senders in them all that happens is one ding shortly after start up and the lamp flashes for a bit them goes steady. A bit of black electrical tape on the dash cover lens solves that.
everything reverts to normal when I swap for my regular wheels with TPMS senders.
My light came on when the temperature dropped a couple weeks ago. One tire was at 23. (only measured one so I got air in them) I got them filled up to 30 at wal mart and tire light is still on
I know it says to wait a while and drive some and itll go off again, mine still hasnt gone off. I haven't driven more than 15-20 miles as ive been driving a short distance.

I think you will find your tire pressures are still to low to reset the TPMS.
The TPMS sensors are calibrated to the manufacturer's recommended tire sizes and air pressures. (32 lb.s air pressures is pretty much standard for most tires) Check your drivers door "B" pillar for the manufacturers tire specifications label. It will have the amount of recommended pressures stamped on it. Make sure your tires when "cold" are filled to that amount minimum. I am reluctant to use the term "For Safe Measure" with this recommendation! Temporarily add a couple / three pounds.
Next, take a drive for a minimum for 15 to 20 minutes, preferably without stopping at speeds above 30 .
On a side note, tire air pressures will change with the temperature. When the temperatures rise so also will the tire pressures. The opposite is true. When the temperatures fall tire air pressures will drop.
The National Highway Traffic and Safety Administration (NTHSA) due to the Firestone tire recall of 2000 mandated Tire Pressure Monitoring Systems be on all new "vehicles" starting with the 2008 model year.
I dont know whats up . Last week it came on low, filled it up to 35 psi. Went off for a day. Came back on. Filled it up again to 35 psi, went off. Came on again
John, if the tire was taking more air, then it was losing air. Maybe (for once in a blue moon) the TPMS was actually giving you good info -- you've got a tire that's going soft. I fear if you left it for a few more days it would become visibly soft and eventually go flat.
Also, I don't know what the weather is where you are but I've noticed that the first time it gets seriously cold -- and that can mean just frosty in September after the warm summer -- the TPMS light will come on. It will go away after I drive a few miles, get the tires warmed up, and then turn the vehicle off; when I restart it will be fine. After a day or two of this behavior in the fall, it will adjust to the new cooler temperature. Same thing may happen again in the winter when the temp makes a severe drop like the first time below 0 F. It must be related to the contraction of the air in the tire as it cools which must lower the pressure enough to trip the device.
I'm not sure on this, maybe others can explain. Does the TPMS only report differentiation between the tires or is there a particular pressure that will actuate it? Like if I ran all my tires consistently soft -- say 28PSI -- would the TPMS illuminate? Or only if 3 tires were at 28 and one was significantly lower? I'm thinking of our Wrangler with OEM tires that take 40PSI and our new Grabber LTs that take up to 80PSI. (I don't run them that high -- rides stiff enough as it is)
