				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.

			P0130 is the pre cat sensor on the left side.   Do you have access to a scan tool with a data stream? | ||
