This Exhaust Gas Temperature Sensor, part number 1618LS, is specifically engineered for PEUGEOT and CITROEN vehicles. It plays a crucial role in monitoring the temperature of exhaust gases, providing vital data to the engine control unit (ECU). Accurate exhaust gas temperature readings are essential for several reasons. They allow the ECU to adjust fuel injection timing, ignition timing, and exhaust gas recirculation (EGR) rates to optimize combustion, reduce harmful emissions, and prevent damage to exhaust system components like the diesel particulate filter (DPF) or catalytic converter. By ensuring this sensor is functioning correctly, you contribute to maintaining your vehicle's fuel efficiency, reducing its environmental impact, and prolonging the life of critical exhaust components. This is a direct replacement part, designed to meet the original equipment manufacturer's specifications for a perfect fit and reliable operation.
