Bank 1 sensor 1 is upstream bank 1 sensor 2 is downstream
Sensor 1 would be before the catalytic converter ( upstream ) Sensor 2 is after the catalytic converter ( downstream )
bank 1 is always the head with the number 1 spark plug and the number 1 sensor is always in front of the converters closest to the motor
Bank 1 is usually on the driver side of the motor and bank 2 is the passenger, sensor 1 is the one on the header and sensor 2 would be after the catalytic converters Bank 1 is the same side as cylinder #1. Bank 2 is the other side.
Bank 1 is the bank of cylinders that contain the number 1 cylinder. O2 sensor 1 is the first O2 sensor in the exhaust system between the engine and the catalytic converter.
Bank 1 is the bank of cylinders that contain cylinder 1. The O2 Sensor 1 is the O2 sensor located in the exhaust system between the cylinder head and the catalytic converter, also known as the "upstream" O2 sensor.
Bank 1 is the bank that sits closest to the front of the vehicle. Bank one is the bank with cylinder # 1. You have 4 oxygen sensors, (bank 1 sensor 1, bank 1 sensor 2, bank 2 sensor 1 and bank 2 sensor2). Follow the exhaust from the head of bank 1. The first sensor you come to is sensor 1, the second is sensor 2.
Bank 1 = The side of the engine the Number 1 cylinder is on Sensor 1 = between engine and catalitic converter Sensor 2 = After cat...
On a Ford Expedition : Bank 2 is the drivers side of the engine Sensor 1 is between the engine and the catalytic converter ( upstream )
Bank 2 is passenger side. O2 sensor 1 is threaded into the exhaust system between engine and catalytic converter.
