    That reading should be taken when the battery has rested 10+ hours.

    But 12.4v would mean it's good

    4 days later, the 12v is fine. I have a driven it around some more. One of the ABS codes is gone. Lights that are on: Maintenance required, TPMS, CEL, VSC, ABS, and now the monitor is saying that it's 36 degrees outside when its really 60 degrees.
    Code are p0138 and C0205 which is O2 sensor 1 bank 2 high voltage and left front wheel speed sensor signal malfunction, respectively. I recharged the hybrid battery as well. Car runs like a scolded dog, I just want to make sure it isn't anything else before I go and get rid of those codes. I have thought about keeping this car. Even if I do and don't decide to sell it, I need to clear those lights before I go crazy!

    Maintence required is a timed mileage light you can turn off yourself. Abs and others might be the wheel speed sensor.

    What would the VSC sensor be? And does anyone have a write up for the 02 sensor?

    You have mentioned in this thread and others that you "read the codes and got only Pxxxx ..." codes. I'm thinking you are not seeing the codes from all the car's computers.

    Are you using Techstream to read the codes or something else?

    I bought techstream. Needless to say, problem solved. Pretty insane what this technology can do.

    The lights were genuine. CEL is off after changing O2. Will be replacing the wheel speed sensor tomorrow I'll see if that shuts off the other 3. Then an oil change for the maintenance required light.
