Bank 2 is passenger side. O2 sensor 1 is threaded into the exhaust system between engine and catalytic converter.
Bank 1 sensor 2 would be the sensor after the behind the catalytic converter.
Bank 1 is the side that cylinder 1 is on, sensor 1 is downstream and sensor 2 is upstream
Bank 1 on a Chevy is the drivers side. Sensor 1 is located in front of the catalytic convertor and sensor 2 is after the converter. Each side has 2 O2 sensors.
