Answer 1
Hello the front of the engine next to the radiator is bank [2] but before you replace the oxygen sensor after the catalytic coverter which is the bank [2] sensor [2] 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? Thanks again -
