This Lambda Sensor, part code 1618HG, 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 allows the engine control unit (ECU) to adjust the fuel-air mixture for optimal combustion. This precise control is essential for reducing harmful emissions and improving fuel economy. Replacing a faulty Lambda Sensor can resolve issues such as poor fuel efficiency, rough idling, increased emissions, and illuminated check engine lights. Trust in the quality and reliability of this genuine PEUGEOT/CITROEN part to restore your vehicle's performance.
