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
sweet thanks, so should i replace it? i have off road h pipe so replacing it would still make the check engine light trigger correct? so i guess mil's are the issue here???
if the heater circuit is bad u need a new o2 sensor...the sims don have anything to do with the heater circuit
ok well i guess new o2 then and i'll go from there... i guess if my check engine light is still commin on after that then i would need to get new mil's?
just for future reference.. bank 1 = the bank the #1 cylinder is on.. IE. passenger side. bank 2 = the opposite side
