2 upstream and 2 downstream for a total of 4 O2 sensors.
4, 2 before the converter on each bank and 2 after(downstream).

Oxygen sensors are screwed into the exhaust on both sides of the catalytic converter.
All O2 sensors are screwed into the exhaust system. Start at the exhaust manifold and work your way back toward the rear of the car and you will find all the O2 sensors.
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 two O2 sensors, one is between the exaust manifold and the catalyst converter and the other right after it.
There are four o2 sensors on a montero sport.
THERE ARE 4 O2 SENSORS. BOTH FRONT O2 SENSORS ARE LOCATED ON THE EXHAUST MANIFOLDS AND THE REARS AFTER THE MANIFOLD/CAT. BANK 1 SENSORS ARE LOACTED ON THE RIGHT SIDE OF THE ENGINE AGAINST THE FIREWALL. BANK 2 SENSORS ARE LOCATED ON THE LEFT SIDE OR RADIATOR SIDE.
O2 sensors on all vehicles are located in the exhaust system. Start at the exhaust manifold(s) and visually work your way back, you will find them.
check your exhaust system there should be a wire running in to your exhaust tat is your o2 sensor good luck There are two o2 sensors, one in the engine and one coming out of the Cat Converter in the exhaust system.
