    so my check engine lights on i have mil eliminators but they are a good 2 years old so they could be the cause of my problem.. but anwyas these are the cosed what showed up.

    P0156: 02 sensor circuit malfunction (bank 2 sensor2)

    PO161: 02 censor heater circuit malfunction (bank 2 sensor 2)

    the main question here is which one is bank 2 sensor 2? is it the rear one on passenger side???
    and would buying new mil's fix this or o2's???

    thanks guys

    just for future reference..

    bank 1 = the bank the #1 cylinder is on.. IE. passenger side.
    bank 2 = the opposite side
