Oxygen sensors play an intricate role in controlling the emissions of a vehicle. These sensors, also known as O2 or Air-fuel sensors, monitor the level of oxygen in the exhaust gases of the engine. This real-time information is used by the engine control unit (ECU) to adjust the air-fuel mixture, ensuring optimal fuel-air ratio for […]
