An automotive oxygen sensor, or O2 sensor, detects the presence of oxygen in your exhaust gases. They can be found in modern cars, trucks, and motorcycles. Its role is to maximize combustion engine efficiency and emission control. Once the sensor reads the amount of oxygen present, it can determine the appropriate amount of fuel to be delivered to the cylinders.   The O2 sensor prevents the so-called knocking from occurring, which can happen when an engine misfires or combusts too soon before it has finished burning both air and fuel.    You can find the oxygen sensors in the exhaust to monitor combustion efficiency in an engine. It can restore some of the air that burned during the combustion process with high-temperature oxygen gas. The sensor uses a heated filament wire or platinum wire as its heat source and emits a low-current electrical current in response to changes in temperature.   What Are the Signs of a Failing Oxygen Sensor?
