bank refers to either passanger or drivers side and infront of the cat. I am not sure which bank is which tho. Most likly its not getting a good reading form it. The foul up after about 50k miles or so. Easy to replace on your own and are about 60$
Jeff, bank one is the passenger side. Sensor two is the one behind the cat. You're lucky, that's the easiest one to reach.... Be sure and check the wiring before calling the sensor bad. Since the wiring travels over the cat, it tends to drop down and sometimes burn.....
Thanks for the info.I just wented to tell you the wife is happy again .The check enginis out Bad wire on O2 sensor,and no more skip, Darnn bosch plugs.replaces with autolight platium.Also got some autolight wires,changed the oil and airfilter.
