Hi, all.

Tire pressure light came on in my 2007 I4. I checked all the tires, including the spare, all close to 36 psi. Even bought a different tire guage, rechecked it, same thing.

Any ideas?

One tire has been missing the stem cover since the last oil change about 4 months ago. Is that connected?

I've read in this forum that the battery in the sensors last about 7-8. years for some members. 2007+8= it's about that time.

The missing dirt cover for the tire valve makes no difference as far as the TPMS is concerned. I would replace it though.
