This Lambda Sensor, part code 161848, is specifically manufactured for PEUGEOT and CITROEN vehicles. It plays a crucial role in your vehicle's emission control system by measuring the amount of oxygen in the exhaust gases. By accurately detecting oxygen levels, the Lambda Sensor provides vital data to the engine control unit (ECU). This allows the ECU to adjust the fuel injection and ignition timing to maintain the ideal air-fuel ratio. A properly functioning Lambda Sensor is essential for reducing harmful emissions and maximizing fuel economy. Replacing a faulty Lambda Sensor can resolve issues such as poor fuel mileage, rough idling, increased emissions, and illuminated check engine lights. Trust in the quality and precision of this genuine PEUGEOT/CITROEN part to restore your vehicle's performance and environmental compliance.
