    Hello all I have gone thru this forums before i started this thread
    I purchased and repairs and very minor front hot 2014 Prius c one feom auctions last week. car was run and drive no issues drove as it suppose to when it arrived , drove around the block few times while hit and no such error . I replaced radiator condenser for the vehicle along with front bumper . finalyl got the car back today from repair shop and this sign came in “Check hybrid system turn off the car something “

    Keep in mind 12v battery was dead when it arrived so I didn’t gave jump to the car 2-4 times and it works . I recharged the battery and got it installed again .

    code I scanned is P0c73 .
    Anyone knows what should I check I am getting mixed reviews . Car only have 98k miles on it. 12v battery starts the car perfectly.

    All help is appreciated .

    pump is the most likely candidate. start by checking the reservoir for movement with the car ready
