How to Install a Universal O2 Sensor on a Mitsubishi Montero – The O2 sensor on a Mitsubishi Montero measures the exhaust gases coming out of the exhaust for contaminants. This information is sent to the Montero’s electronic control unit, and then the air to fuel ratio is adjusted accordingly. After 75,000 miles, the O2 sensor may start to fail. When it finally fails, your vehicle will run very poorly. For the Montero, you can install a universal O2 sensor. These sensors replace the factory sensor.
