O2 sensors names
 

I replaced both O2 sensors on the passenger side and the upstream on the left side - located in the catalytic converter but still have a fault code P0130 bank 1 sensor 1 malfunction. Question is which O2 sensor is this. I have yet to replace the far right sensor… downstream I believe it is.

What year?

P0130 is the pre cat sensor on the left side.

Do you have access to a scan tool with a data stream?
