darrencnz 10 Report post Posted May 6, 2016 Hey Guys Question, i didnt really take much notice when i removed my pre cat O2 sensors and was just wondering if it matters which way around they go. By that, i mean is there a specific front bank and rear bank that nee to be plugged in to the right lugs or does it not matter which way round they go? I cant remember when i first put them in and a quick search online has yeilded very little so am assuming it doesn't matter, can someone weigh in on this?

Thanks, yeah i thought i remembered having to check this when i first installed the engine, i think i also recall the front plug coincidentally referred to the front bank too but i am going to double check...
