This Lambda Sensor, part code 9813838380, is a direct replacement for your PEUGEOT or CITROEN vehicle. It plays a crucial role in your car's emissions control system by measuring the amount of oxygen in the exhaust gases. This data is then used by the engine control unit (ECU) to adjust the fuel injection, ensuring the ideal air-fuel ratio for efficient combustion. Proper functioning of the Lambda Sensor is vital for maintaining optimal engine performance, reducing harmful emissions, and improving fuel economy. A faulty sensor can lead to increased fuel consumption, rough idling, poor acceleration, and illuminated check engine lights. Manufactured to meet the high standards of PEUGEOT/CITROEN, this sensor guarantees reliable and accurate readings. Replacing a worn or faulty Lambda Sensor with this genuine part will help restore your vehicle's performance and ensure it meets emission regulations.
