It would be on the opposite side as cylinder #1.
Catalytic converter efficiency failure bank 2.Catalytic converter efficiency failure bank 2.
bank 2 is the drivers side of the engine bank 2 - sensor 1 - is before the exhaust passes through the catalytic converter bank 2 - sensor 2 - is after the catalytic converter ( downstream )
Bank 2 catalytic converter efficiency failure.Bank 2 catalytic converter efficiency failure.
BANK # 1 is the passenger side of the engine / BANK #1 SENSOR # 1 is in the exhaust before the catalytic converter / BANK # 1 SENSOR # 2 is after the catalytic converter ( downstream ) ------------------------------------------------------------------------------------------------------------ BANK # 2 is the drivers side of the engine / BANK # 2 SENSOR # 1 is in the exhaust before the catalytic converter / BANK # 2 SENSOR # 2 is after the catalytic converter ( downstream )
Bank 1 sensor 2 is the sensor after the catalytic converterBank 1 sensor 2 is the sensor after the catalytic converter
Bank 1 is the driver's side, bank 2 is the passenger side. Then you will have sensor 1 and sensor 2. Sensor 1 is before the catalytic converter (closest to the engine), and sensor 2 is after the catalytic converter. So Bank 1, Sensor 2 is: the driver's side , after the catalytic converter.
Try to picture this Bank 1 Sensor 1 Bank 2 Sensor 1 Catalytic Conv. Catalytic Conv. Bank 1 Sensor 2 Bank 2 Sensor 2
Bank 1 is the oxygen sensor either screwed into ,or above the catalytic converter. Bank 2 is below the catalytic converter.
Assuming this vehicle has duel exhaust with duel catalytic converters, bank 2 sensor 2 would be the O2 sensor after the passenger side catalytic converter.
On GM, bank one is drivers side of engine, bank 2 is passengers side. Sensor(s) 1 is the upstream sensor, meaning BEFORE catalytic converter. Sensor(s) 2 are located downstream, or AFTER the catalytic converter, therefore, bank 2, sensor 2 is located in the exhaust pipe leading from the passenger side of engine and after the catalytic converter.
Sensor 1 would be before the catalytic converter ( upstream ) Sensor 2 is after the catalytic converter ( downstream )
Bank 2 is the drivers side of the engine Sensor 2 is downstream of the catalytic converter ( after the exhaust gas has passed through the catalytic converter )
