The front oxygen sensor before the catalytic converter is usually called 'upstream' or Sensor 1. The rear oxygen sensor installed after the catalytic converter is called 'downstream' or Sensor 2. A typical in-line 4-cylinder engine has only one bank (Bank 1). Therefore, in an in-line 4-cylinder engine, the term "Bank 1, Sensor 1" simply refers to the front oxygen sensor. "Bank 1, Sensor 2" is the rear oxygen sensor. A V6 or V8 engine has two banks (or two parts of that "V"). Usually, the bank that contains the cylinder number 1 is called "Bank 1." Different car manufacturers define Bank 1 and Bank 2 differently. To know which is Bank 1 and Bank 2 in your car, you can look it up in a repair manual or you can google it, mentioning the year, make, model and engine size of your car. For example, according to Toyota bulletin TSB-0398-09, in a V6 Camry, Highlander, Avalon, Sienna and Solara, bank 1 is at the back, bank 2 is in the front. Similarly, in a V6 2003-2008 Mazda 6 or V6 Mazda Tribute, bank 1 is at the back, bank 2 is at the front. In a 2003 Nissan Maxima, bank 1 is at the back, bank 2 is in the front.
