Does anyone know which one of the four 02 sensor is Bank 1 sensor 2 on a 03? I have an idea thanks to Adam but need to be 100% sure before I buy the wrong one

Thanks

 

Bank in on the number 1 cylinder, bank two is on the number two side.
Sensor one is the sensor before ce cat. converter and sensor 2 is after de cat. converter.

So bank 1, sensor two, is the sensor on the firewall side, after de cat. converter, normally on the exhaust pipe under the car.

 

That not the one I though it was.....Thanks. I guess my 02 silulator is not working
