Tire Pressure Monitor Sensors (TPMS) are a real pain.
mine goes off when temps stay below 55F. I ignore it because pressures are fine at 32-34 psi. as confirmed by digital pressure gage i keep in car.
damn dealership says “just add 4-5 more pounds of air”
(they be hoping i’m stupid enough to overinflate, and buy new chinese tires from them......not...)
