An oxygen sensor, also known as an O2 sensor, is an electronic device that measures the proportion of oxygen (O2) in the exhaust gas of an internal combustion engine. It is a key component of the engine’s electronic control system and plays a crucial role in optimizing engine performance, reducing emissions, and improving fuel economy. Oxygen sensors are typically located in the exhaust manifold or exhaust pipe, where they are exposed to the hot exhaust gases.
Over time, oxygen sensors can become fouled or contaminated by carbon deposits, lead, or other combustion byproducts. This can lead to inaccurate readings and reduced engine performance. Cleaning an oxygen sensor can help to restore its accuracy and improve engine performance. However, it is important to note that oxygen sensors are delicate devices and should be handled with care.
