Original Quality Mass Air Flow Sensor 1120940048 for M112

This mass air flow sensor OE 1120940048 is an indispensable intake sensing component specially designed for Mercedes Benz M112 engine. Mounted on the engine intake manifold pipeline, it precisely detects the mass of incoming air flowing into engine cylinders and converts real-time airflow information into digital electrical signals and transmits them to the ECU. The engine control unit calculates accurate fuel injection amount and ignition advance angle according to the air mass data collected by the sensor, so as to form a reasonable air-fuel mixture ratio, which greatly affects engine starting condition, idle stability, throttle response, power performance and fuel consumption level. Adopted high precision sensing chip and high strength anti-corrosion plastic shell, the sensor owns reliable dustproof, heat resistant and anti-electromagnetic interference characteristics. It can continuously output stable and accurate signals under complicated working conditions with varying intake temperature and engine load. Each product will go through strict signal calibration, aging test and sealing inspection before delivery to ensure consistent measurement accuracy. Once the mass air flow sensor ages or malfunctions, the vehicle will have many obvious faults, such as rough idling, weak acceleration, excessive fuel consumption, black smoke from exhaust pipe and engine warning light lighting up on the dashboard. In serious cases, the engine may lose power or stall suddenly while driving, bringing hidden dangers for driving safety. This premium aftermarket sensor keeps the same mounting size and electrical parameters as the original component, enabling plug and play installation without extra modification. It restores the accurate intake air measurement function of M112 engine, improves fuel combustion efficiency and cuts down harmful exhaust emissions, providing a dependable and economical replacement option for maintenance and overhaul of Mercedes Benz M112 engine.
