This Lambda Sensor, part number 16289W, is specifically engineered for PEUGEOT and CITROEN vehicles. It plays a crucial role in your vehicle's emissions control system by measuring the amount of oxygen in the exhaust gases. By accurately reporting oxygen levels, the engine control unit (ECU) can adjust the fuel injection to maintain the ideal air-fuel ratio. This precise control is essential for maximizing fuel economy, reducing harmful emissions, and ensuring your vehicle runs smoothly. Replacing a faulty Lambda Sensor can resolve issues such as poor fuel economy, rough idling, increased emissions, and illuminated check engine lights. Trust in the quality and reliability of genuine PEUGEOT/CITROEN parts for a perfect fit and optimal function.
