    those are the codes that lit up on my Prius. I bought this Prius several months ago off auction and ended up replacing the front end with a nose cut. Wanted to see if anyone had similar codes and what you did to configure the problem?

    I am guessing the first code should be P0A93.

    Those are 'permanent' codes—the car's memory of an issue it had but no longer has.

    It appears that at one time you had a dodgy inverter water pump (P0C73, P314A), and that led to the inverter overheating (P0A93).

    But those codes no longer show as current, which either means (a, great) that you have changed out that pump and resolved the problem, or (b, less great) that you cleared the codes or something and they just haven't come back yet.

    Assuming you did the great thing and changed out the pump, the 'permanent' codes will just go away by themselves after a while, when the car convinces itself on a few consecutive drives that the problem is fixed.
