Bank 1 would be the passenger (right) side of engine. Bank 1 Sensor 2 would be the O2 sensor after the catalytic converter on the passenger side.
Bank 2 is the drivers side of the engine , sensor 2 is in the exhaust pipe after the catalytic converter ( downstream )
Bank one, sensor one on a 2003 Chrysler Town and Country is in the exhaust immediately behind the engine. Sensor two is farther down in the side of the catalytic converter.
There are 4 of them, 1 located before and after the cats on both sides. Drivers side is bank 1 and passengers side is bank 2
Bank 1 is the passenger side of the engine in a Mercury Mountaineer ( V6 + V8 ) Sensor 2 is after the catalytic converter ( downstream )
