    I have a 2nd Gen Prius. My TPMS light is on. I checked my tire pressure and one tire was low. I added air so the front are 35 PSI and the rear 33 PSI. i pressed the reset button, holding it until the light flashed three times which it did. However the light stays on. I tried this several times. What am I missing here?
    Thanks for the wisdom.

    You may want to have a tire shop scan for your TPMS sensor, one or more of TPMS sensor battery may have been out of commission

    The batteries in the TPMS sensors only last so long. Easiest thing to do is nothing, just monitor tire pressures more often, at least 'till next tire replacement.

    Some US states with annual car inspections will fail you for tpms sensor light being on, others don't mind.

    Have you driven it a couple minutes since airing up the tires? It can sometimes take a bit for the previously alarming sensor to report in again with the new good pressure.

    How old are the TPMS sensors? If original, they are already beyond the usual expected battery life, thus needing replacement. If you recently bought this car used, then you likely won't know their age.
