The exhaust pressure sensor plays a crucial role in modern vehicle emissions control systems. By precisely measuring the pressure within the exhaust manifold or DPF (Diesel Particulate Filter), it provides vital data to the engine control unit (ECU). This data allows the ECU to make real-time adjustments to fuel injection, ignition timing, and other parameters to ensure efficient combustion and minimize harmful emissions. A malfunctioning sensor can lead to increased fuel consumption, poor engine performance, illuminated check engine lights, and failed emissions tests. This specific sensor, part number 1623137380, is manufactured by PEUGEOT/CITROEN to meet stringent OEM quality standards. It is designed for a direct fit and reliable operation, ensuring compatibility and performance with your PEUGEOT or CITROEN vehicle. Regular maintenance and replacement of critical sensors like this one are essential for maintaining your vehicle's health and environmental compliance.
