I'm here in the Chicagoland area and yesterday I ventured out into the tundra of snow and cold. Drove a couple miles and my TPMS lit up and started screaming.

Weird as my tire pressures are up to snuff. Only thing I could thing of was that the snow packed into and around the wheels. My understanding is that the TPMS measures pressure based on wheel rotation and maybe the snow packed around the wheels caused them to whack out.

Any thoughts? I haven't ventured since then. This morning it's a brutal -15F.

Thanks,
George

 

Did you switch over to winter tires?

 

More than likely, the cold weather killed one of the batteries in the TPMS sensors. They typically only have a lifespan of about 6 years.

If the light blinks for 60 seconds, and then goes solid. This is the case. There are procedures to run a sort of diagnostics and identify which sensor, and reprogram as well.

This actually happened to me last year. Once temps warmed up to the 40's, i reprogrammed the sensor and it worked fine.

Just this past weekend, it hit -5 out, and my TPMS light came on again blinking for 60 sec first. So right away, i know the same sensor that was weak last year has crapped out again. Cold kills batteries.

I might buy a single sensor to replace it, or wait til spring and try to reprogram it again.

 

Another bone chilling night. Went to start up and TPM light was on. Lucky to be on my way to the stealer for Annual State Inspection.
Long story short 2 were dead. When I got home you guessed it, light was back on. Headed back to replace the last one.
The first one went bad under similar conditions last year.

 

-15F??? Haha. Here in winnipeg it just hit -37C....which is -34.8 F....for the past 3 weeks. Just another winter......


Why I live here ill never know

But anyways, I never even thought about the sensors themselves having batteries. That could explain the false tpms indications.

Battery just gets weak and can't transmit a signal anymore. Car can't read it, so on comes the light telling you there is an issue.


I waited til springtime, and did the self-reset and it worked. I'm going to cross my fingers that it works this year again because I really don't want to spend the time and money to replace TPMS sensors....even though I beleive in doing things right.

 

Thanks everyone for your feedback. Sounds like batteries as I haven't installed any new tires since 2 years ago.

Now on to find the reset procedure. We're on our way to a tropical near-40 degrees this weekend so I may give that a try.

Worked like a charm when i did it

 

After a few years of the light coming on during long drives, it finally died for good. So I replaced one a couple weeks ago. So far 3 have lasted for 10 years.

I wish I had known how easy it was to diagnose which one was bad or I would have had it fixed a couple years ago.
