    Hi Everyone

    I live in Quebec and purchased a set of 4 x Schrader 33500 EZ tpms from Canadian Tire
    • Single Sensor Solution combining 314.9, 315 and 433 MHz applications into one sensor performing a TPMS sensor relearn on the vehicle
    (Their website claims that these are compatible with 2023 Toyota Prius Prime so long as they are programmed at installation)

    I paid another $40 for the installation while they were mounting winter tires on their own set of brand new rims
    After I came back home and was driving in the evening the tpms indicator on the dash lit up and I see --- in the dash for the TPMS screen

    Is there a re-learn or calibration that needs to be done for the car to pick up the new TPMS sensors. If someone has had a similar problem, I would appreciate to find out how it was resolved.

    I want to be informed before I go back to the tire shop and demand why its not working.

    Thanks in advance

    I think it's in the manual. There's a whole section on it with a lot of blah blah in it.
    Here's only one page, for rotation.
    I think it's needlessly complex.

    The car can remember two sets of tyres. It is capable of detecting new sensors without special tools, but only they're if they're of the newer type.

    From the "so long as they are programmed at installation" note, yours are presumably of the older type, which would mean it can't detect them from scratch.

    Given that the car is apparently not listening to these sensors, your best hope is that installers DID program the codes in, as they were supposed to, but they helpfully programmed them into the blank spaces for the second set, rather than overwriting your initial set.

    But they did that without actually selecting the second set, which you should be able to do now.

    Procedure for that is in a page close to the one posted above - "Selecting wheel set". Menu entries TPWS Setting -> Tyre Set Switching -> Register Valve / ID -> Tyre Set X.

    If you flip that, maybe it will start working. (After maybe 5 minutes of driving).

    If not, try flipping back to the other set, and then try the rotation thing above.

    Last resort before going back to the installers would be try a from-scratch registration as per the section "Registering ID codes", but I would not expect that to work with the sensors you have.

    (And I would be concerned that using that menu entry would make it forget a sensor set, thus forcing you to go back to the dealer to reprogram the old-style ones. Take care not to use it on the old sensors' set when you get them working. But maybe it's sensible enough to not blank codes unless it sees some new codes to replace them with.).

    Car Care Nut video about the two Toyota sensor systems, which may be helpful:
