They should be in the exhaust system close to the engine ( either in the exhaust
manifold outlets or the
exhaust pipe ) before the exhaust enters the catalytic converters
Bank 1 is the passenger side of the engine and sensor 1 is the upstream sensor
Bank 2 is the driver side of the engine and sensor 1 is the upstream sensor on that side
