PEUGEOT/CITROEN Lambda Sensor 9811388380

This Lambda Sensor, part number 9811388380, is a direct replacement part manufactured by PEUGEOT/CITROEN. It plays a crucial role in your vehicle's exhaust system by measuring the oxygen content in the exhaust gases. This data is then sent to the engine control unit (ECU) to adjust the air-fuel mixture for optimal combustion. A properly functioning Lambda Sensor is essential for several reasons. It directly impacts your vehicle's fuel economy, ensuring that the engine doesn't run too rich (wasting fuel) or too lean (potentially causing engine damage). Furthermore, it is vital for emissions control, helping your vehicle meet regulatory standards by ensuring the catalytic converter operates efficiently. Symptoms of a failing Lambda Sensor can include a check engine light, reduced fuel efficiency, rough idling, and increased emissions. Replacing a faulty sensor with a genuine PEUGEOT/CITROEN part like this one will restore your vehicle's performance and environmental compliance.
