Hello everyone, I can seem to find the thread on here about this so I apologize if I had to start a repeat. I have a 2010 V6 and its throwing the codes on the catalytic converter 7e8. I'm being told its just the O2 sensor on the Cat but not sure where that is or what the part is. Everyone place ive looked like Autozone for diagrams show something generic and multiple sensors. Not sure which one is the culprit I need to change out is the issue im running into.

These are the pics im finding but nothing looks right to me.





1 - B52F Heated Oxygen Sensor Bank 2 Sensor 2 (LLT)
2 - B52E Heated Oxygen Sensor Bank 2 Sensor 1 (LLT)
3 - B52C Heated Oxygen Sensor Bank 1 Sensor 1 (LLT)
4 - B52D Heated Oxygen Sensor Bank 1 Sensor 2 (LLT)
