Yes, an O2 sensor (oxygen sensor) is essential for modern vehicles as it monitors the level of oxygen in the exhaust gases. This information helps the engine control unit (ECU) optimize the air-fuel mixture for efficient combustion, improving fuel efficiency and reducing emissions. A malfunctioning O2 sensor can lead to poor engine performance, increased fuel consumption, and potential damage to the catalytic converter. Therefore, it's important to ensure that the O2 sensor is functioning properly.
