Vehicle Oxygen Sensors – What Do They Do?
Let's talk oxygen. Not only is it vital for humans, but your car also needs it to function as well. Without the optimal oxygen ratios, your vehicle isn't going to run at its top performance levels. That's where your car's oxygen sensors come in... What Does An Oxygen Sensor Do? Oxygen sensors optimize performance and emissions by monitoring the oxygen ratios in the exhaust system and reporting the Aforementioned to the P.C.M. (vehicle’s main computer). Too much oxygen read by the oxygen sensor is a lean mixture and generates nitrogen-oxide contaminants. Extremely lean conditions may cause overheating and engine damage. The opposite is known as a rich mixture and can cause pollution and an engine that misfires or runs rough. Oxygen levels vary from outside factors like altitude, temperature, load weight, engine temperature, barometric pressure, etc. Oxygen sensors will calculate the ratio of oxygen to fuel in the exhaust and communicate that information to your car's computer. The computer will then adjust the gasoline inputs based on the balance to keep it at optimal [...]
