I've got a problem with a code that keeps popping up on my kids car. I understand that it is an 02 sensor on passenger side behind the cat (bank 2 sensor 2). I changed out the sensor and cleared the code but the code keeps coming back. I've seen several posts on different forums and there seems to be different views on what sensor belongs to bank 2 sensor 2. Am I right in replacing the one I mentioned? If so, what else could be causing the code to come back? I checked the wiring around the sensor and there isn't any obvious signs of damage. Thanks in advance for any advice and suggestions.
