In '97 it's located in the exhaust pipe right near the Cat Conv, I just saw it last week when mine was in the air. Could it still be in the same place or near there in 2000? It's worth a look. If you can't get your' up on a lift, just try and find a curb and drive so the car is part on the road and part on the curb side and then you've got lots of space to climb under. Hope your search is fruitful.
1st o2 senor is between exhaust. 2nd o2 sensor is under shifter
Remove the vacuum hose from the O2 sensor. Remove the wiring harness. Remove the O2 sensor retaining screws. Reverse the process to install the new O2 sensor.
O2 sensor? Hey its a part and parts wear out. Oil additives or fuel additives can ruin an O2 sensor as well.
See related link which includes instructions for testing any O2 sensor.

The check engine light would illuminate and set a code for the bad O2 sensor.
The oxygen sensor for bank 1 sensor 1 for a 2000 mercury mountaineer is on the cylinder #1 side.
the upstream o2 sensor is mounted in the exhaust before the catalytic converter and the downstream sensor is after the cat. conver.
You don't. Buy the correct sensor.
