I suppoused it was from bank 2, I just have the doubt of where in the car is the bank 2,
I know that there are 4 sensors, and I do not want to replace one that is working fine,
Additionally, Are the three sensor the same?,
If I bought it I just buy an oxygen sensor for contour 98 duratec? or OD I have to specify which one?
