P0161 - O2 sensor, which one?
Hello guys, I got 1998 C43 AMG.
I got check engine light couple times, when I scan it I get P0161 code: Oxygen Sensor Heater Circuit Bank 2 Sensor 2.
Can somebody tell me which one it is exactly, right or left (please explain which side is right which is left : )) and if its before cat or after cat.
Maybe somebody had this issue and know what exactly is wrong...
I was at the dealer doing some service and the light came up again and they scanned it again and they said its O2 sensor and misfire codes: P0161, P0141, P0300, P0306, P0307, P0308 but when I scan it at AutoZone I just get P0161.
Greatly appreciate any help

bank 2 sensor 2 means its drivers side or left if you are sitting in the car,sensor 2 means its the one post the cat(your car must likely has pre and post cat sensors)the easiest way to figure out which side is bank one or two is to locate cylinder no 1,(1,2,3,4)are bank 1 and (5,6,7,8)are bank two.If it sad bank 2 sensor 1 ,it would mean that pre cat sensor is bad.
