    Here in Ottawa, our Clarity spent it's first night outside at -15c, plugged in to 120V. This morning when my wife went to drive home, the check engine light was on the whole way.

    I hooked up an OBD2 scanner and the two codes present were PODA8 and P1A91.

    I looked them up and this is what I found:

    P0DA8 - HV cell voltage sensor software - there was a recall for the Accord Hybrid about this a couple of years ago.

    P1A91 - 14 Volt Power Module Temperature Sensor 1 Circuit Low Voltage.

    Am I the first to see these? If anyone has had them, how involved was the fix?

    A quick search showed you are the first to post those codes, so you'll be the guinea pig for what's involved. I hope it's a simple and quick fix.

    So the dealer cleared the codes and said that cold temps can cause a slight dip in voltage when you start the car, and that triggers these codes. If it happens again I have to bring it back and they'll dig deeper. I mentioned that here in Ottawa we regularly hit -30C, so if the car can't go to -15C without an error code then that's a design flaw. We'll see...

    Interesting. 5F would be somewhat routine for many places that a Clarity lives in the U.S. Thanks for posting the codes. I wonder if we'll see more of those.
