Im new to the forum, lots of great info here. Im hope someone can help. I have an 2001 5.4 Supercrew 4x4. The scanner said I have to replace O2 sensor 2 bank 2. I have seen a couple of conflicting posts of which bank is which. Some say it is on the passenger side some say drivers side. Can someone please shed some light on this for me. Thanks in advance.
