Legacy tire pressure warning light

[mlateacher]

The tire pressure light blinks on and off and then a letter i appears next to the D symbol. My mechanic has checked the pressure frequently and says nothing is wrong other than the cold weather causing the issue. Any ideas?

Ive heard that if it blinks it's a bad Tpms. I also heard that you should check the spare tire.

What is the pressure when the light is on or flashing?

Have you tried to overfill by maybe 2-3 PSI and see if it stops warning you?

Also, TPMS's rely on batteries that often die. Any tire place should be able to scan all four tires and tell you immediately if you need to replace the TPMS's. How old are they?
