Not passing smog check

Bank 1 is pass/side exhaustpipe/converter bank 2 is on the driverside,this car has two converters, so you have 4 oxygen sensors, one before and one after the converter on each side, so bank 1 sensor1 is pass/side before the converter, bank 1 sensor 2 is pass/side after the converter, then bank 2 sensor1 is driverside before the converter, before means starting at motor, then bank 2 sensor 2 is driverside after the converter, heres a diagram to help, i hope this is helpful.

There are 4 oxygen sensors. bank one is the right (passenger side) bank 2 is the drivers side. The front sensors are sensor 1 and the rears are sensor 2. So if it needs bank 1 sensor 2 that would be the right sensor, behind the cat converter. Bank 1 sensor 1 is in front of the converter. Be sure thats what you need from the smog shop, do not take advice from a auto parts store IE Ottozoo, they tell everbody they need oxygen sensors.
