I got a new catalytic converter for my Honda Civic 2005 HX car because the "coal" inside went lose and was just making noise inside of it. While trying to take off the old O2 sensor I ended up rounding it and in frustration I cut its wires and now it is no longer functional.
A friend told me he has an old O2 sensor for his Civic, but it went on the catalytic converter that was on the header not on the secondary catalytic converter.
So let me give you the idea, my HX Civic has 2 catalytic converters and 3 O2 sensors. An upstream one before both of the catalytic converters and 1 after each catalytic. My question is can I interchange the O2 sensors after the catalytic converter?
