This Lambda Sensor, part number 1628NY, is specifically engineered for PEUGEOT/CITROEN vehicles to ensure precise exhaust gas monitoring. A functioning Lambda sensor is crucial for the engine control unit (ECU) to adjust the air-fuel mixture, leading to improved combustion efficiency and reduced emissions. By accurately measuring the oxygen content in the exhaust gases, this sensor provides vital data to the ECU. This allows for real-time adjustments to the fuel injection and ignition timing, optimizing engine performance and preventing issues like poor fuel economy, rough idling, and increased pollution. Replacing a faulty Lambda sensor with this genuine PEUGEOT/CITROEN part will restore your vehicle's performance and help it meet emission standards. It's a critical component for maintaining a healthy and efficient engine, contributing to a smoother driving experience and lower running costs.
