Something many people don't know is that you actually have to drive your car to get the sensors to report information. When I start my car, the pressure readout is from when I previously stopped driving the car, an before getting out of my neighborhood, the new and cold pressures are reported.
This much I am sort of aware of even with sensors that only report a low warning. Took about half a mile for my wife's 2010 Subie LGT to recognize that I'd added a little air as its warning lamp had just illuminated.
I'd be careful about driving through cold water deep enough to fully immerse the wheel at the bottom (say, 6" deep") as this might result in odd sensor behavior that takes longer to self-correct. Been there.
