How An Oxygen Sensor Works?
Oxygen Sensor O2 Working Of O2 Sensor in car Maintenance Oxygen sensors are made of reactive materials which limits their lifespan. Aside from mechanical failures such as shorted heating elements or physical damage, these sensors will usually last around 80,000 miles. If an engine has a mechanical failure such as a head gasket (coolant) or an issue that causes oil consumption (rings, valve guides), it will drastically shorten the sensor's life. When replacing your oxygen sensor, be sure to use a high-quality OEM (Original Equipment Manufacturer) part. Cheaper sensors aren't as accurate and don’t last as long as an OEM sensor will, and can cause performance issues as well as emissions problems. Vacuum leaks in the intake system, can give a false the sensor false readings and cause poor engine performance. History As fuel injection evolved, so did the oxygen sensor. Evolving from a one-wire sensor that grounded through the outer case, to a four-wire sensor that grou...
