Car Oxygen Sensors

What exactly is an oxygen sensor? This lesser known part has quite the impact on your car. Almost all vehicles manufactured after 1980 have this. It's a spark plug-shaped mechanism that's a significant component in your vehicle's emissions control system. This sensor measures the oxygen content of the exhaust, checking it hundreds of times per minute with tremendous accuracy before transmitting the data to your car's computer. Basically, the oxygen sensor's tasks are to help the engine perform efficiently and make sure that your vehicle produces better emissions.

A car oxygen sensor on a recent model will be positioned in the engine's exhaust manifold to detect whether the mixture of gasoline and air going to the engine is lean or rich. Rich mixture has too much fuel and is hazardous to the environment. On the other hand, a lean mixture has too little fuel and tends to generate more nitrogen-oxide pollutants. The latter is also responsible for poor engine performance.

Once the sensor determines if the mixture is lean or rich, it'll send a voltage signal to the computer. A command is then issued to adjust the mixture before it enters the engine. This procedure assures that the engine will be given not just the best possible fuel economy but the lowest possible exhaust emissions as well. As you know, those are two results that you should greatly monitor. A responsible car owner isn't only concerned with how powerful his ride is, but also with how it affects the environment.

Among the types of these sensors used in vehicles are the single wire variety and the heated variety. The latter features a heating ingredient that helps maintain the proper operating temperature. For your sensor to run properly, there are four fundamental conditions that should be considered. First, your vehicle should have good electrical connections to secure the path of its low current. It also needs outside air supply that must flow through the internal section of the sensor. The next factor is the proper operating temperature. That's because the ECU won't recognize the voltage signals until the sensor arrives at approximately 600 degrees Fahrenheit. Finally, remember to use non-leaded fuel to extend the sensor's lifespan.

When your oxygen sensor malfunctions, the computer will no longer be able to determine the air and fuel ratio. It'll end up guessing, and your car will begin to perform poorly and will demand more fuel than it needed before. For renewed engine performance, better gas mileage and healthy emissions, you'll need to install a replacement sensor as soon as possible.
