This Lambda Sensor, part number 1618R0, is specifically engineered for PEUGEOT and CITROEN vehicles. It plays a crucial role in your vehicle's emission control system by measuring the amount of oxygen in the exhaust gases. By accurately detecting oxygen levels, the Lambda Sensor allows the engine control unit (ECU) to adjust the fuel injection and ignition timing. This precise control is essential for maintaining the ideal air-fuel ratio, which directly impacts fuel economy, engine power, and the reduction of harmful emissions. Replacing a faulty Lambda Sensor with this genuine PEUGEOT/CITROEN part will help restore your vehicle's performance, improve gas mileage, and ensure compliance with emissions standards. It is a vital component for a healthy and efficient engine operation.
