Hello Fellow Members,

I have a question, I have a 2002 Dodge Ram 1500 4.7L and the engine light came on, so I took it to autozone to have a test ran on it and the only code that came up on the PCM is P0161, which its saying it is the oxygen sensor 2 in bank 2 and my problem is I dont know which one is sensor 2 in bank 2. I took a picture of the sensors, the picture is taken from the back of the truck leading to the front of the truck.



here is the direct link to the image if it will not show up:

I have the sensors marked with red and green circles, can anyone please help and tell me which sensor is sensor 2 in bank 2, the red or the green?

Thank You in advance...

 

Bank 2 is the side that does NOT have cylinder #1 (passenger side) and sensor 2 is after the cat converter. Sensor #1 is between the engine and converter.

 

okay, I kinda get what your saying, I am not a big car person but I made a layout of the truck, lol haha dont laugh at it -=)

I own a 2000 Dodge Ram 1500 4x4 5.2 litre, truck is running rough scanned with genesis bank 2 o2 sensor is putting out a constant reading of 5.0 . Tested o2 sensor with multimeter, sensor varies from 0.01 to 0.09 indicating sensor is good.

Why is the truck getting this false reading? What wiring do I need to check? Any help is greatly appreciated.

 

...yup, rear O2 sensor after cat, passenger side...
