    2009 Prius. I am looking up from under the car, the oil filter is to my right. On the left there are two coolant lines going into the transmission. There is a black electrical conduit going from left to right, it has a junction above the coolant lines...that junction is crumby, looks like it has been chewed on, and I see white, probably white wires. This junction goes to a gray plastic part (sensor??) that is bolted to the trans. What is this sensor and has anyone had experience trying to fix a damaged junction like this? Years ago the protective shield under the car engine was lost. Any help is appreciated. I can try to get a pic. thanks.

    A six wire connection - is likely wiring for a "resolver". That's a fancy position sensor for one of the hybrid drive motors. The sensor is mounted inside the transmission. The gray part with the bolt is just the mating connector (and wires) that goes through the trans case.

    I would (carefully) unlatch the connector and inspect the wiring harness. To me it definitely looks nibbled. If the wires are ok, then wrap it in electrical tape and put it back. If there's "minor" damage to the wire insulation, you can use "liquid electrical tape" then regular electrical tape. If the copper conductors are damaged, then you have to repair things (somehow).

    Yes, that's right. The color coding on the visible part of the connector matches the hybrid wiring diagram.

    Problems can arise due to wire breakage or short circuits, then such error codes will appear.
