Due to the computerized automobile engines today, tuning up of our engines seems to be hard. Additionally, along with the advancements made in technology, there are new crucial components that have to stay within the bounds of environmental laws regarding emissions. Among these crucial parts is your Ford Explorer oxygen sensor. Such sensor should effectively monitor the engine exhaust for most common causes of air pollution. The oxygen sensor is basically the measuring probe that determines the amount of oxygen in the exhaust. It is mounted inside the exhaust pipe to continuously monitor the exhaust gases. This sensor signals the engine computer to adjust the air/fuel ratio to make sure that gasoline combustion is completed. A well-functioning Bosch Oxygen Sensor can help reduce harmful emissions improving the engine performance and fuel efficiency at the same time. Normal aging process can eventually cause your oxygen sensor to stop working. Contaminants from normal combustion and oil ash will accumulate on the sensing element reducing the sensor’s capability to respond quickly on changes in the air/fuel mixture. The oxygen sensor’s output voltage in your Ford Explorer might not be as high as it was before, giving the false impression that the air/fuel mixture is leaner than it is.
