This Lambda Sensor, part number 1628PL, 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 unburned oxygen in the exhaust gas. By accurately monitoring the oxygen levels, the engine control unit (ECU) can adjust the fuel injection to achieve the optimal air-fuel ratio. This precise control is essential for maximizing fuel economy, reducing harmful emissions, and ensuring your vehicle passes emissions tests. Replacing a faulty Lambda Sensor can resolve issues such as poor fuel economy, rough idling, increased emissions, and illuminated check engine lights. This genuine part ensures compatibility and reliable performance, maintaining the integrity of your PEUGEOT/CITROEN's sophisticated engine management system.
