Ford Explorer Oxygen Sensor
Your engine's best fuel efficiency happens when it has the correct ratio of fuel to oxygen. The Explorer oxygen sensor is the component that measures this ratio. Running too much or too little fuel causes emissions failures, which is bad for the engine, increases the inefficiency of your vehicle and damages the environment.
