Hello the front of the engine next to the radiator is bank  but before you replace the oxygen sensor after the catalytic coverter which is the bank  sensor  you need to check the cross counts.I suspect the catalytic converter is not working properly.

Thanks for the location of the sensor. However, I do not understand what you mean "check the cross counts". Will you explain?
