How do I know if I need the O2 sensor for cylinders 1-3 or 4-6? Is bank 1 cylinders 1-3 and bank 2 cylinders 4-6? Error code reads “Oxygen sensor upstream of catalytic converter, bank 2 - signal too low” and “…upstream …, bank 1 - signal too low”. Thanks for the video as well!

Hey omg please help me, do you know which catalytic converter is bank one and bank two? Is bank one the top converter in the video or the bottom one?

To my knowledge bank 1 is the first sensor (nearest the bumper) and bank 2 is the one after it. Then there are pre-catalytic and post-catalytic sensors. So two banks (cylinders 1-3) (cylinders 4-6). Pre-catalytic and post-catalytic. Near top of engine is pre and near bottom of engine is post. Hopefully that helps. Hopefully Pelican Parts confirms my understanding is correct
