    The shop is telling me that the codes say the accelerator pedal needs to be replaced in our 2008 'spare' Prius.

    He says there are dual controls, one a backup to the other, and when they go out of sync the whole assembly needs to be replaced. (Even thought it appears to be working fine.)

    Is it correct that the pedal can't be repaired - it just needs to be swapped-out?

    Other than Toyota, is there a reliable, and affordable, recommended source for a replacement?

    Thanks.

    Please ask your shop for the actual, exact trouble codes they are seeing, and post those here. A trouble code is five characters, where the first is a P, C, B, or U, the next is a 0, 1, 2, or 3, and the rest can be any digit 0 through 9 or letter A through F.

    A Prius has sensors both on the accelerator pedal and on the throttle itself (two sensors, for redundancy, in each place), and there are codes about one and codes about the other, and they all look similar and they all have similar descriptions that start "throttle / pedal position sensor / switch", and people mix them up all the time. It's no fun replacing the wrong thing.

    Here is a post you can refer to for more information.

    Since this is rarely posted as a problem, I would think there would be plenty of used parts available. All will be somewhat reliable, due to the rare failure occurrences that are listed on this forum.

    In fact I might have one for sale LOL

    Pretty sure this has shown up several times previously and is always a misunderstanding of the DTC.
