This Lambda Sensor, part code 1618AV, is specifically designed 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 monitoring oxygen levels, the Lambda Sensor provides vital data to the engine control unit (ECU). This information allows the ECU to adjust the air-fuel mixture in real-time, ensuring the most efficient combustion possible. Proper functioning of the Lambda Sensor is essential for maintaining optimal fuel economy and reducing harmful emissions. Replacing a faulty Lambda Sensor can resolve issues such as poor fuel mileage, rough idling, increased emissions, and illuminated check engine lights. This genuine PEUGEOT/CITROEN part guarantees compatibility and performance, restoring your vehicle's emissions system to its intended specifications.
