    P0A80 = HV Battery is bad.
    * replace w/ NEW for reliability or go w/ 2k1Toaser's cylindrical cell replacement kit.
    * used/rebuilt/remanufacture are a poor choice b/c the are made from old modules
    * module replacement is a band-aid fix and is NOT reliable.
    * Read Post #9&#11 to help you decide which way you want to go: Indianapolis area battery repair? | PriusChat
    * if you have to pay for labor, time for a new car or a younger used car.

    P0125 = Insufficient coolant temperature for closed loop fuel control.
    * you have a leak in the cooling system?
    * air entered the cooling system, likely due to a leak.
    * someone recently serviced the cooling system (drain/fill, replaced a pump or both) and did not bleed all the air out.​
