SOURCE: Where is the O2 Sensor located on 2003 Ford Focus?

The code will tell you which O2 sensor it is.
The code will point to either bank 1 sensor 1; bank 1 sensor 2; bank 2 sensor 1; bank 2 sensor 2.

From what I remember with a focus, it should only have 2 sensors, sensor 1 will be located before the cat, and sensor 2 will be located after the cat.
