    TPMS works without sensors?

    Occasionally I would have my TPMS lights go off for no reason. Tires dont have the sensors, but pressures would be slightly low on occasion. Yesterday I got a flat and the TPMS went off.

    Does the system work without the sensors???

    It uses the wheel speed sensors to guess if you have a flat. If all the wheels go flat the same amount, it probably won't notice!
