TPMS light on

My tire pressure light came on a couple of weeks ago. Twice, I have checked and adjusted the tire pressure, but noted no low (or high) tire pressures. I had an identical problem when it got cold last winter. Anyone else have this problem? Faulty TPMS sensor or something? Thanks

It could be a faulty sensor. What pressures are you running?

Our 2010 Patriot (company car) with 1800km/1000mi has a similar issue. I've added air twice in that time. We had an 08 temporarily and it had the thing. That one needed air every 5-6 days on 2 or more tires...and not always the same tires. The pressure was down to 205kPa on all 4 tires. s/b 235kPa. Equal to about a 5psi difference. We'll be taking it back to the dealer to see what they say.

In that case I'd say the sensors were doing their job. It sounds like a leak in the tire or valve stem could be the problem and not the sensors.

Around Calgary the temperature can vary from 40 above zero farenheit to 30 below zero and in a matter of hours. I try to keep the tire pressure around 35 lbs Cold and let it drop to 31 lbs when way below zero. Ignorance is bliss with my steel wheels without sensors for the winter tires but I didn't have any rim leaks or valve leaks with any of the 8 wheels for the Patriot.

Yes, I did forget temperature changes quickly in some areas. I've been between -3 and 17 F for the last couple of weeks. My Kumhos are pumped up to 38 normally.

sometimes, Fix-a-flat will ruin the sensors too. My poor old dad made that mistake twice on his car, drives him crazy when I have to drive to his house just to tell him not to do dumb things

Leaks...to almost equal pressure...on all 4 tires still seems mighty odd. The previous Patriot had 1 tire.

it is probably a bad sensor, they go bad and are fairly easy for a shop to replace, very difficult to do on your own.

It will come on due to the change in air temps.... Cold air takes up less room. If your tires all read accurate pressure, don't worry about it. Especially if the light goes out when the tires warm up.

The rule of thumb is for every 10° Fahrenheit change in air temperature, your tire's inflation pressure will change by about 1 psi (up with higher temperatures and down with lower).

Also remember that the sticker on the door is for MINIMUM COLD air pressure and that the MAX air pressure is on the tires themselves. Try filling them up cold 1/2 way between the 2 extremes and see what happens. If this cures the problem then you may want to adjust the pressure for ride comfort, handling, etc.

If you go to the link in post #2 you'll find that member was getting interference from his I-phone charger.
