Bank 1 sensor 2 is located downstream, usually behind the catalytic converter. Regardless of the bank, all oxygen sensors use the same naming pattern. Take it to a local auto parts store and have the code scanned again (for free). The I6 only has 1 bank. Sensor 1 would be the front and sensor 2 would be the ...
