It's not very likely that a 4 cylinder will have 2 banks, unless the engine is in a "v" confinguration. Haven't heard of a V-4, but it's possible.
Oxygen sensors for inline engines are on the exhaust manifold, just past the point where all 4 cylinders have joined.
There are two . One is ahead of the converter & one is below the converter. They are called upstream & downstream sensors.

Inside the fuel tank.
it is different for location

The difference between an outline and a contour line is location. An outline is used to draw the outermost form on an object, while a contour line is used to depict details inside the form of an object.
On a 1999 Ford Contour : In the passenger compartment fuse panel ( # 27 is a 15 amp fuse for the cigar lighter )
