How many o2 sensors

depends on engine and options...
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").
It has 3 , Just follow the exhaust lines , one when u pop the hood , one underneath and the one in the back of the engine , that’s probably the bad one . I replaced the two easy to see ones and kept popping codes, took to mechanic and he showed me the third one . Kinda hard to see . Just jack up the car and look towards the back of the engine . Replaced it and no more codes !!
