    Hi all,
    So putting back together another Gen 2 battery for a friend, and of course the top sensor broke. This has happened 3 times to me now on the older battery packs as they are now brittle.What codes will this throw and how can I fix this besides micro soldering it back yogether?

    Thank you in advance

    Is this what you're talking about?

    2004-2009 Toyota Prius Hybrid Battery Temperature Sensor Wire OEM | eBay

    I usually get them for cheap or free from battery re-builder.

    I did replace the whole harness once that had a bad sensor.

    And having one of the three banks sensing pack temperature that you can see on Dr. Prius app will did indeed throw a red triangle and make the car unusable.

    But when they break usually it's only the plastic clip not the sensor so you can just use a zip tie or electrical tape to hold it in place and it will work find that way.
