Help please with info, which side of a 2002 Mits Montero sport is a B2 oxygen sensor on ... driver or passenger and is it before or after the catalytic converter? Thanks

 

Bank 1 is where cylinder 1 is, which is the front cylinder on the passenger side. Bank 2 is where cylinder 2 is, which is directly across from cylinder 1, driver's side front cylinder. California certified 3.0 and 3.5 Montero Sports have four oxygen sensors. Sensor 1 is the one before the catalytic converter, sensor 2 is the one after the cat. So bank 2, sensor 2 would be the one on the driver's side after the cat. Federal-only vehicles only have 2 oxygen sensors, one on each bank.
