Every modern vehicle and most of the cars manufactured after 1980 feature an oxygen sensor. It is a spark plug shaped mechanism that’s designed to do a very critical job in your automobile even in the harshest of environments. A significant component in the vehicle’s emissions control system, oxygen sensor measures the oxygen content of the exhaust after passing through the catalytic converter. This electronic device feeds data to the engine management computer after accurately checking the exhaust hundreds of times per minute. Basically, the oxygen sensor’s tasks are to help the engine achieve an efficient performance and to make sure that vehicles produce few and safer emissions.

Oxygen sensors, especially on modern vehicles are 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 as unburned fuel causes pollution. If there’s a rich mixture, there is also a lean mixture. This mixture has too little fuel and tends to generate more nitrogen-oxide pollutants and worse, it could sometimes cause poor engine performance and even engine problems.

Once the oxygen sensor detected that the mixture is lean or rich, it will send a voltage signal to the engine management ECU computer, which in turn issues a command to the mixture control solenoid found in the carburetor 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.

Among the types of oxygen sensors used in vehicles are the single wire oxygen sensor and the heated oxygen sensor. The latter type of sensor features a heating ingredient to help in the warm up which leads to proper operating temperature and to keep up that temperature. For your oxygen sensor to run properly, there are four fundamental conditions that should be considered. First, your vehicle should have good electrical connections. The reason for this is that the oxygen sensor creates low currents and it requires clean and excellent electrical connections. The oxygen sensor also needs outside air supply that must flow through the internal section of the sensor. The next factor that should be given consideration is the proper operating temperature. It is because the automobile’s ECU will not recognize the voltage signals until the sensor arrives at approximately 600 degrees Fahrenheit. Also, remember to use non-leaded fuel all the time because leaded gasoline can damage the sensor rapidly.

When the oxygen sensor in your car starts to fail or malfunction, the computer can no longer determine the ratio of the air and fuel and thus, it will end up guessing. If this happens, your car will start to perform poorly and will demand more fuel than it needs before. It is in this situation that replacement oxygen sensors are really needed. Replacement oxygen sensors are designed to take the place and do the job of your vehicle’s existing oxygen sensor. They are usually made as efficient as the original ones so that engine performance, gas mileage and vehicle exhaust will not be compromised.
