    Hi Friends,
    I'm getting Two code on scanner Tool P101D and P0A80. Is there any one tell me what i can do.
    Replace O2 sensor or is there any issue of battery. Because when i clean the code it comes again after driven 200-250km.

    I have 2012 prius currently with 99000 km mileage.

    sounds like you're battery is going south. check the 12v health to make sure the cpu's are getting enough voltage to produce good information

    do a load test on the 12v battery. a low voltage to the computers can cause flaky codes to pop up. if the battery is good, check the trouble codes with tech stream to make sure your reading all the right codes.
    then proceed to the service manual for troubleshooting and repair.
    if the P0A80 persists, you probably need a new hybrid battery. although, it would be worth disassembling and checking for corrosion.
    have you cleaned the cooling fan and intake grille?
