well i just recently replaced my pre-cat o2 sensor and it's just behind a steel plate on the front of the motor that has about four bolts i think which is also connected to your Power Steering. The o2 sensor is behind that screwed into the exhaust. so make sure that the car is cool when handling this area. The o2 sensor looks like a spark plug almost, installed the same anyway. Hope this helps somewhat. I'm sure it's the same thing as mine because i own a 2003 focus.
Upstream is before the catylitic converter, downstrean is below the cat.
Only two, upstream and downstream.

It is located before the Calaytic converter

The easiest way to reset the 2008 Ford focus low tire pressure sensor is to remove the fuse. Keep the fuse out for 10 seconds and then replace it to the original slot.
The best way for removal is to wiggle the sensor while pulling upwards. This speed sensor is known to break during removal, if it does it will have to be drilled out to remove the broken piece.
This will be located probably just before the catalytic converter on the exhaust
It is most likely your oxygen sensor
