how many o2 sensor on a mazda tribute 2008

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.
