    New to Prius and forum. Thought I should show my findings for a code which came up for voltage sensing.
    I searched and came up with a supposedly broken lead. Didn’t know exactly where but a few guys here kinda pointed to where the buss bars are. I looked pretty good and couldn’t see any real break. Decided to pull it off and take it in the house to really look good at it. Turned out it was in the connection to the voltage reader. One of the pins had corroded. Was gonna buy a used setup for $200, but with only 4 screws I got in the box and soldered a jumper to the pin inside. Hope this helps anyone with the same problem.

    If that works then great, it's just that the one pic shows corrosion on the terminals to either side of the failed one in the orange connector. So I don't know how long before you have problems (again).

    Kudos for going the "repair it" route though.
