Are the primary o2 sensors interchange or have certain sides for certain colors?
I just had downpipes installed and have thrown a few codes... i had a leaky charge pipe that may not have helped but regardless i was wondering if the o2 sensors before the cats have to be in a certain side.
I heard the grey wired o2s go on one side and the black on other... after my DP install ive gotten a few codes and saw that where the grey wire is on the bottom o2 is not where the grey wire is on the top, they are switched...
is this incorrect? Or are they interchangable on the left and right? Or is it true grey on one side black on the other...
Please help me out if you know... thanks
