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.
upstream
Contour lines crossing a small stream will point upstream as they represent the elevation change of the terrain. This means that the elevation increases as you move in the upstream direction.

On a contour map, streams flow perpendicular to the contour lines. When the contour lines are spaced closely together, they indicate a steep slope, while widely spaced lines suggest a gentle slope. If the contour lines form a "V" shape that points upstream, the stream flows downhill, away from the point of the "V." Therefore, the direction of flow can be determined by observing the orientation of the contour lines in relation to the stream.
Because we know that water cannot flow uphill, the flow must go from higher contours to lower ones.
Pre or Post?
Hi, I have a 96 ford contour.. they all seem to have emission issues dont they? On mine, I just replaced the 2 it has. They are called upstream and downstream o2 sensors. I liked the prices from rockauto.com where they were shipped from.
Contour intervals
Inside the fuel tank.
it is different for location

On a 2000 Ford Contour, there are typically two oxygen sensors: one upstream (pre-catalytic converter) and one downstream (post-catalytic converter). The upstream sensor is located on the exhaust manifold or just after the manifold, while the downstream sensor is positioned after the catalytic converter along the exhaust pipe. Both sensors can be accessed from underneath the vehicle, although you may need to raise the car for better access.
