    Dear All,
    I'm owning a Prius Plug-in 2012, there are around 120 000 miles on it. A few days ago after the car washes the engine light pop-up with the code P1420. I tried to change the gas cap seal and reset the code, but a few days after the engine light pop-up again with the code P1422. Is there anyone experienced these?
