How does a low pressure sensor work on a car?
Low-line direct TPMS systems simply prompt a low pressure warning light, leaving it up to the driver to determine which tire needs more air. Hi-line direct TPMS systems display the individual pressure of each tire on the dashboard.
Can a tire pressure sensor measure wheel speed?
Yes, a pressure sensor that doesn’t actually measure pressure… Indirect TPMS instead uses your car’s ABS system, tapping into the wheel-speed sensor to see if one tire is rotating faster than the others. Underinflated tires have smaller circumferences, which in turn means they have to rotate faster than a properly inflated tire.
