are all honda/acura 02 sensors the same? I have one from long time ago that I never used but don't know how to advertise it.

 

There are three major versions:
one wire non-heated narrow band
four wire heated narrow band
five wire heated wideband

They are pretty generic from there. Primary and secondary may differ, I don't remember.

Advertise it with a part number if you have one.

 

thanks! I figured its not a o2 sensor from my other post
