By measuring the oxygen content of the exhaust gas, the lambda sensor supplies the necessary information for optimal air/fuel mixture to the engine control unit, thereby providing the basis for more efficient and lower-pollutant combustion. Use of a lambda sensor contributes towards compliance with exhaust and on-board diagnostic requirements.
