An oxygen sensor is a device that measures the amount of oxygen in a vehicle’s exhaust gas. It is also known as an O2 sensor or a lambda sensor. The oxygen sensor helps the engine control unit (ECU) to adjust the fuel-air mixture and optimize the combustion efficiency. A faulty oxygen sensor can cause various problems, such as increased fuel consumption, poor engine performance, and higher emissions. Therefore, it is important to check and replace the oxygen sensor regularly.
