This Lambda sensor, part number 55282500, is specifically engineered for Fiat, Alfa Romeo, and Lancia 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 information allows the ECU to adjust the air-fuel mixture in real-time, ensuring the most efficient combustion possible. Proper functioning of the Lambda sensor is essential for maintaining optimal fuel economy and reducing harmful emissions. Replacing a faulty Lambda sensor can resolve issues such as poor fuel mileage, rough idling, increased emissions, and illuminated check engine lights. This direct-fit replacement ensures compatibility and reliable performance, restoring your vehicle's emission system to its intended operation.
