I read somewhere that newer cars are smart enough to just lock onto the
four sensors that are usually the closest and spinning in unison.
I don't know if that's universal, though.  My daughter's Accord doesn't
use sensors at all, comparing wheel speeds to determine loss of
pressure.

 For a couple of weeks before I swapped the tires I was getting the low
pressure alert. The first time was disconcerting since i was out at the
range which is outside of town. I checked the pressures and one was 29 psi
so I got out the inflater and brought them all up to 35. Eventually the
light went off. Then it came on again on a rough road out to a trailhead.
I did a walk around. Everything looked okay so I ignored it. The next day
it was off, and then a day later it was on.
 I bought the car in 2020 but it was a leftover 2018. Because of covid it
only has 27,000 miles, less than that on the street tires because of the
swap so they're OEM. The only thing I can think of is one or more of the
batteries in the sensors are starting to fail. PITA. I'll check the tread
and may get new tires in the spring along with a sensor replacement.

It could be a premature battery failure, or it might be a bad/damaged sensor pickup at the wheel location .. latter can happen from road debris, and/or off-roading.
If the TPMS system tells you which tire is low, you could do some troubleshooting by doing a tire rotation to see if the "low" follows the tire or stays at the same location.
