    Hi all,
    Long time listener, first time caller. I have a 2008 Prius Base, that I replaced the TPMS sensors on. I will admit they're cheap Amazon sensors. The computer can see them and their associated ID numbers and the computer can see their pressures and temperatures. But when I try to scan them for diagnostics, they fail, saying they don't respond. I cannot get the light on the dash to turn off, what am I missing here?

    What computer are you talking about?
    What are you using to scan the TPMS sensors?

    I took the car to Discount Tire and they scanned the sensors and "loaded" them into the TPMS Computer. I took a picture of the sensor IDs from their scanner.

    I am using an Autel MaxiAP200 Bluetooth OBD Scanner. I don't know exactly what module of the car I'm in when I read the data. Before I had the sensors installed, the Tire Pressure would read "0" or "-" in every corner. After having the sensors installed, they read the pressure and temperature, but it's odd to me that the light is still on. If I open the TPMS function (which I'm assuming is the TPMS module), it doesn't show any faults. Not sure what is happening here.
