<![CDATA[Ford O2 sensors, same or different?]]>I noticed on the 2001 expedition I bought that it looks like they put an O2 sensor with the long cord before the cat. All the ones online say the long cord is the back one.

There is conflicting info online. Does it matter, are all o2 sensors the same? Before cat, after cat doesn't matter?
