The engine relies on many sensor readings to keep the engine in optimal operating conditions and maximizing efficiency and performance. One of the most important sensors in your vehicle is the oxygen sensor. It is commonly called O2 or lambda sensor and is responsible for determining the amount of oxygen present in the exhaust gases that leave the engine. The presence of oxygen in the gases can tell how much fuel is needed for stoichiometric combustion or how much fuel is being wasted. A high amount of oxygen indicates a lean fuel-air mixture, and the ECU increases the amount of fuel supplied. Conversely, a low amount of oxygen indicates a rich fuel-air mixture, and the ECU reduces fuel supply. This is a continuous process that ensures the engine is always running efficiently, decreases fuel consumption, and regulates emissions.
