On my 1988, O2 sensor is threaded into side of exhaust pipe underneath near transmission. When I changed it, it was difficult to remove. I had to keep heating the exhaust pipe with a torch to get it out.
O2 sensors are always located on the exhaust system.
All O2 sensors are threaded into the exhaust system at various points. Upstream O2 sensors are located before the catalytic converter(s) and downstream O2 sensors are located after the catalytic converter(s).
There are four o2 sensors on a montero sport.
The 2.5 has 2 O2 sensors (both on top of the engine) and the 3.5 has 4 O2 sensors (two on top, and two under the car).
The check engine light would illuminate and the code(s) would point to one or more of the O2 sensors.
The o2 sensors screw in. There is a special socket for removing the 02 sensors with a slot in the side to clear the wiring.
