The Mitsubishi Mirage has had a long and varied history. Introduced as a subcompact platform during the fuel crisis of the 1970’s, it has evolved into a versatile platform of station wagons, hatchbacks, coupes, and sedans throughout its life. It was replaced by the Mitsubishi Lancer in 2002.

One trait that has remained consistent throughout the life of the model is its fuel efficiency. Of course, the only way to maintain good fuel efficiency during the life of an automobile is to keep up with engine maintenance.

Mitsubishi carefully tunes its engine to deliver the best compromise of economy and performance. The key to this formula is maintaining the proper fuel to air mixture in the combustion chamber. The Mitsubishi Mirage oxygen sensor is the final check in the engine to ensure that the proper ratio is achieved. It is mounted on the exhaust before the catalytic converter and measures the amount of oxygen present in the exhaust. Too much oxygen and it will increase the amount of fuel delivered into the chamber, too little, and it restricts it. A faulty oxygen sensor will likely deliver too much fuel into the chamber, which will, ironically, not only rob you of power, but will also drastically cut into your fuel economy. If you have noticed a significant drop off of power in your car, and an engine that just seems not to sound healthy, consider replacing your Mitsubishi Mirage’s oxygen sensor. It is a regular maintenance item that should be changed at manufacturer specified intervals.
