    I got a new Hybrid Battery installed by Greentec and when I picked it up they told me about 2 codes it was reading that they said i needed to fix still.

    C1466 - Right Rear Speed Sensor
    P0121 - Throttle Pedal Position Sensor

    I drove home about 20 miles and no lights or messages came on but they did say that if I didn't fix the C1466 then it would affect the cars ability to charge the hybrid battery.

    Should i go ahead and replace the right rear hub assembly that has the speed sensor in it? Or pay for a diagnostic now that the battery has been replaced? I was at least planning to wait on the throttle position sensor because I have a 12 hour job waiting for next weekend already (A/C evaporator) to get the car "fixed." Plus a tire swap and an oil change

    PS I also noticed the passenger front and passenger rear windows don't work from the drivers controls but they do work from each respective door. If anyone knows how to fix that also that would be awesome.

    Thanks in advance

    Get a code reader that will read ALL the Prius codes, and check it out yourself.
    Did you have those codes before the battery was replaced?

    If you do not presently have any warning lights or messages on the dashboard, you do not have any current trouble codes.
