Tpms warning even if tire is ok?

I am not sure why, but I have been getting a yellow error on my tire despite having 40psi on my tire. Anyone know if I might be doing something wrong or if the car is being strange?

I have no idea!

How about just reset/reboot your car?

If that doesn't fix it, how about go to Menu > Service > Wheel Configuration, switch to another size so the car can reboot to the new wrong size then choose the correct size again?

What pressure is the tire? You probably just need to add a little air. Stop by a tire store, most are happy to help for free.

I had it at 40, but I just read the jam it turns out I need 45

That makes sense!

My door jam says 42 so I thought 40 is not that off. However, since yours says 45, 40 is quite a bit 5 off away!!!

Time for more air as @ewoodrick said!
