from other wiki answers bank 1 is the passenger side, bank 2 is the drivers side under drivers seat, sensors one are the one before converters towars engine and sensors 2 are the ones behind (after converters) , you have to use a 22 millimeter wrench to remove, bank 2 sensor 2 is blue plug, bank 2 sensor one I believe is white or gray color... this is from previous experience, I am 99% sure, I still have my 1997 expedition with 190000 miles and still runs fine, I had only changed transmission and fuel pump and other minimal items due to normal wear and tear.... hope this helps. sometimes it is easier to have a special sensor socket like the mechanics which has a slit along side of it to slide over sensor while not damaging the wires and removing the sensor, it is sometimes easier to remove the front wheels to get to sensor 1...
