What is an Oxygen Sensor ?
Too little oxygen indicates a rich mixture, which wastes fuel and reduces economy, and the unburned fuel results in excess emissions.
So, a properly working oxygen sensor is a necessity for any vehicle. Neglecting to replace a bad oxygen sensor will usually result in damage to your catalytic converter.
Functioning like a monitor, your oxygen sensor works like this: the O2 sensor tip is located inside of your exhaust pipe, the oxygen sensor detects the percentage of oxygen in the exhaust .
If the mixture is too rich (too little oxygen) or too lean (too much oxygen) than the oxygen sensor sends a signal to the ECU telling it to adjusts the amount of fuel entering your engine accordingly.
Too much oxygen in the exhaust gases indicates a lean mixture. A lean mixture tends to produce more nitrogen oxide pollutants NOx, and in some cases it can cause poor performance including misfire and even engine damage with the engine running too hot.
Oxygen Sensor install position:
The oxygen sensor is located in the exhaust manifold downpipes before the catalytic converter or between the exhaust manifolds and the catalytic converters.
What does an Oxygen Sensor do in the car ?
When a gasoline-powered engine burns gasoline there is oxygen present. Oxygen in an engine is the result of a number of factors including the air temperature, altitude, engine temperature, load on the engine, and barometric pressure. The ideal ratio for oxygen and gasoline is 14.7:1, which slightly varies depending on different types of gas. In the instance that there is less oxygen present fuel will remain after combustion, which is referred to as a rich mixture. On the other hand, if there is more oxygen present it is referred to as a lean mixture. Both the rich and lean mixtures are bad for your car, as well as for the environment. A rich mixture results in fuel that is not burned that creates pollution. A lean mixture generates nitrogen-oxide pollutants, which can lead to decreased vehicle performance and engine damage. Oxygen sensors are positioned near points in the exhaust system so to determine if there are rich or lean mixtures in your car. Typically, an O2 sensor creates a voltage due to a chemical reaction resulting from an off-balanced gasoline to oxygen ratio. Most car engines can determine how much fuel to expend into the engine based on the voltage of the O2 sensor. If your oxygen sensor fails to function properly, your engine management computer cannot determine the air to fuel ratio. Therefore, the engine is forced to guess how much gasoline to use, resulting in a polluted engine and a poorly functioning vehicle.
