I got a low tire pressure light on the information screen... I Checked pressure and it was fine...

I think my TPMS failed... :-\

It probably did not fail but needs recalibrating. I seem to have to do this twice a year (seasonal) even though the tire pressures are correctly set.

are u using nitrogen? if not thats could be due to change in temp! and once u drive it or move that changes and it goes off or resets.

It's cuz of the cold weather probably. Mine did that the other day too when we hit 40,s overnight for the first time this fall. Just driving on them and heating them up shut the warning off.

+1 DRE, once my warning came on, just driving and heating tire turned itself off.

... and don't forget to check the spare tire as well.

^^ No sensor in there, but good to check it twice a year, to set the proper pressure.

Yep... Well I thought at first it was because they weren't heated...

I drove for maybe about 10 miles, but it was still on. I dropped by the dealership, because its on the my way to work. They fixed it and said they reset the TPMS and refilled the tires to 36PSI. (It was still at 28PSI after the10 mile drive)

I guess that is our threshold 28PSI?

I wouldnt just assume its weather. Could have a nail or something in the tire. Worth checking to make sure

If ALL 4 tires were at 28psi, that means its been a while since the air was properly checked & set for a cool 36psi.

The threshold is set during the tire pressure initialization process.. Meaning its based off the PSI set to each tire.

I’ve gotten mine to 27-28 psi at the track with no light..

I have also found a nail in one not to long ago, with 24 psi and Light On

Good thing we have the fun warning light for the nails..

I have learned that more often than not the TPMS light coming on is attributed to faulty TPMS sensors. That's why I had them taken out and the light from under the dash as well. Amen.

I'd replace the faulty sensor, not remove the whole system. So far the TPMS has worked great for me, not only on my Lexus but in other cars as well. I've found nails thanks to the sytems, without it I'd probably be spending money on new tires.

I've had far too many problems with faulty or broken TPMS sensors. I opted to have the system removed.

That's interesting. In three years on this board, no one has complained about faulty TPMS sensors in any Lexus product. Incompatible wheels, sure, but never the sensors. Add to this you can't remove the warning from the Information Display and I'd say your solution is a lot less than stellar. Sounds like installer fail, not Lexus fail.

Lexus technician fail who not only curbed the rim on the seating machine but also broke the sensors in all four rims. Cost the dealership a rim and four TPMS sensors... when one of them broke a few weeks later I opted to have the system removed. It's just a matter of exiting that screen in the ID every time I start the car. A pain in the ***, but much less a pain than having to go to the dealership every other week.
