There's a total of 4 Co2 sensors one on each side above catalytic (upstream) and one below (downstream) for each side.
Don't be fooled by the sensor codes, misfires are usually not caused by bad sensors, sensors detect an issue in that bank but not necessarily the sensor itself, usually caused by lack of fuel or spark. Most common issue are bad ignition coils.
