I have a 2004 Silverado 4.3l engine, my questions is are all 4 02 sensors the same are they interchangeable
The oxygen sensor's are heated. so I guess that's where you are comming up with the word heated. Bank means- what side of the engine that the oxygen sensor is on. Bank 1 or bank 2
Heated oxygen sensor heater circuit malfunction (bank 1, sensor 1): Open or short in heated oxygen sensor heater circuit Heated oxygen sensor heater malfunction (Haynes Repair Manual)
Bank 1 is the part of the exhaust stream that includes cylinder #1. Sensor 2 is after the catalytic converter.
The HO2S (Heated Oxygen Sensor) bank 1 is between the manifolds and the Cadillac Converter. Manifold Exhaust (T) > "HO2S Sensor" > Cadillac Converter > muffler
bank 1 is the one closest to the firewall. sensor 1 is the first one exhaust gasses will come in contact with after leaving the cylinder head.

Bank one on your vehicle is on the back side of the vehicle. Sensor 1 is the first sensor coming from the engine in the exhaust, the one before the catalytic convertor.
if it is a V8 bank 2 is on the right (passenger side). sensor 1 is before the catalytic converter (sensor 2 is after)
Where are the Bank 1 Sensor 1 oxygen sensor on a 1998 ford explorer?
bank2 - opposite side of cylinder #1 sensor 1 - in front of cat converter
It's underneath the vehicle in the exhaust pipe after the cat convertor.
Bank 2 is the drivers side of your engine on your Ford Sensor 1 is in the exhaust before the exhaust enters the catalytic converter
