An O2 sensor in a vehicle plays a crucial role in monitoring the level of oxygen in the exhaust gases that are emitted from the engine. The O2 sensor in a car monitors air/fuel levels in the exhaust. It sends this data to the engine control unit (ECM), which adjusts the air-to-fuel ratio for efficient combustion. This helps optimize engine performance, reduce emissions, and improve fuel efficiency.
