What is a Ford Explorer Oxygen Sensor, and why is it installed on your vehicle? What's more, why should you make sure it's functioning? It is true that today's new, high-tech vehicles have many more parts than their ancestors. Because fuel economy is on most people's minds these days, the Ford Explorer Oxygen Sensor is installed in order to address the issue. For all driving conditions, there are ideal fuel to air ratios, or "mixtures," that maximize both engine performance and fuel efficiency while minimizing exhaust emissions.

A leaner mixture (more air, less fuel) means lower emissions, and is sufficient for most highway driving over level terrain during warm or temperate weather. The Ford Explorer Oxygen Sensor measures oxygen levels in the exhaust, then sends an electronic signal to the fuel-injection system, which makes adjustments to the mixture accordingly.

When an oxygen sensor fails to function properly, engine performance will be lowered, fuel can be wasted and harmful exhaust emissions may result.
