One... It's screwed right into the exhaust manifold. It's very easy to get to but can be hard to get the old one out... They make special sockets for O2 sensors.
I own a 97' geo but have two sensors...
From 1996 on, the system is OBD-II, which has two oxygen sensors, one on the exhaust manifold and a second one on the catalytic converter. Pre-96 only have one on the exhaust manifold. The sensor wiring varies with 3-pin and 4-pin variations.
I have a 99 Metro 1.3L. This car has two oxygen sensors, one in the exhaust manifold and the other is after the Catalytic Converter. Hope that helps.

There are a total of ( 4 oxygen sensors ) according to the engine wiring schematic for the 1997 Mercury Mountaineer in my Haynes repair manual ( 2 oxygen sensors are " upstream " sensors used by the PCM to adjust the air / fuel ratio of the engine ) ( 2 oxygen sensors are " downstream " sensors / catalyst monitors )
You must mean Oxygen sensors. There are 2 upsteam (O2 sensors) and there are 2 downstream (catalyst moniters).
