The oxygen sensor reports live information about the engine's air/fuel mixture to the powertrain control module, (Computer). This information is used primarily to help calculate fuel delivery to the engine, which changes continuously while it is running. If the engine is running lean, the powertrain control module will sense this from the oxygen sensor's signal and increase the air/fuel mixture to the engine. Conversely, just the opposite occurs when the engine begins to run rich. On OBDII-equipped vehicles, the sensors are also used to help determine the efficiency of the catalytic converter. The powertrain control module does this by comparing the signal of the sensor located at the inlet of the catalytic converter with the signal of the sensor located at the outlet of the converter.

There are two oxygen sensor for Mitsubishi Outlander. Front Oxygen Sensor and Rear Oxygen Sensor
If the vehicle was built with an oxygen sensor, you will need an oxygen sensor.
The second oxygen sensor is now used downstream of the catalytic converter to monitor converter operating efficiency.
The oxygen sensor(s) before the catalytic converter(s) is used to determine the air / fuel ratio of the engine
It's integrated into the oxygen sensor. Buy a new oxygen sensor and you get a free oxygen sensor heater.
Remove the oxygen sensor vacuum to. Remove the oxygen sensor screws. Reverse the process to install the new oxygen sensor.
Remove the vacuum hose from the oxygen sensor. Remove the oxygen sensor retaining screws. Reverse the process to install the new oxygen sensor.
An O2 sensor is used to check the level oxygen in your blood. On a car it measures the oxygen content of the exhaust to the adjust air/fuel ratio
To replace the oxygen sensor disconnect the oxygen sensor electrical connector. Use an oxygen sensor socket to remove the sensor. spray the sensor with penetration oil if it is difficult to loosen. install in reverse.
