Bank 1 is the part of the exhaust stream that includes cylinder #1. Sensor 2 is after the catalytic converter.
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

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.
On a 2003 Oldsmobile Silhouette, the heated oxygen sensor (HO2S) bank 1 sensor 1 is located in the exhaust system, specifically upstream of the catalytic converter. It is typically found on the exhaust manifold or in the front pipe leading to the catalytic converter. This sensor monitors the oxygen levels in the exhaust gases to help regulate the engine's air-fuel mixture.
On a 2002 Monte Carlo, the heated oxygen sensor (O2 sensor) bank 1 sensor 1 is located in the exhaust manifold, upstream of the catalytic converter. It is typically positioned on the driver's side of the engine, where it monitors the oxygen levels in the exhaust gases before they enter the catalytic converter. Accessing it may require some maneuvering around other engine components.
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
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
