So the indicator came on this morning before I went to work . . I checked all 4 tires and none of them seemed low to me. I even put more air in all of them since I wasnt sure which tire exactly is low. So now this indicator wont turn off. Anyone had this problem before? And how can I turn this off?

 

what psi is it reading?

 

33 psi is the norm and it's also written on the side of your door..... mine too showed up this morning, all of them reading around 23psi on the stick. Pump them all up to 34psi cause I know the cold weather is coming.

 

What year is your car? It's possible one of the batteries in a sensor went south.

 

2006 300awd

 

Batteries supposedly last 5-7 years, I think, so it's plausible. I think you'll need a shop to test them.

 

wow mine just happened today as well,,,

 

mine been on for the last 4months..

and the oil maint sensor also on..

 

Correct me if I'm wrong, but could it be that the secondary TPMS set got turned on?

 

doesnt the spare have TPMS too or no?

 

I forgot about that, yes, check this FIRST. The switch is under the glovebox.

 

i had mine come on as well. Took my car to the shop, they pluged the computer/code tester to my car , the guys said that everything seems to be in order and all of the sensors work. He turned the indicator light off. After about two month it happened again , i took it in to the same guy. Same senario.Here we are two month later and the light is on again. This time i am just gonna ignore it. Everything seems to be working and i have plenty of air in the tires. I dont know what the problem is.Go figure.

 

I would check your spare tire as well. My wife's RX350 had the same problem about 1 year ago. I checked pressure in all 4 tires and couldn't get the light to go off. Found out that the spare tire is also hooked-up to the TPMS, so I put air into the spare and the light went off. Good luck!
