New Mass Air Flow Sensor For Mercedes & Sprinter 280217517 917864

Mass Air Flow Sensor for Mercedes & Sprinter

This mass air flow sensor measures the volume of air entering the engine and sends that reading to the ECU so fuel delivery stays accurate, and it cross-references OEM part numbers 280217517 and 917864.

Overview

This mass air flow sensor is a direct-fit replacement for worn or failed sensors on Mercedes and Sprinter vehicles. The mass air flow sensor helps the engine control unit calculate the correct air-to-fuel ratio for smooth running and efficient combustion. It suits owners and mechanics replacing a faulty sensor that is causing rough idle, poor mileage, or check engine codes.

Good To Know

Q: Will this sensor clear my check engine light? A: It can resolve codes tied to a failed mass air flow sensor, but the codes should be read first to confirm the sensor is the cause. Q: Is installation difficult? A: Most installations involve unclipping the connector, removing the retaining screws, and swapping the sensor, so basic hand tools are usually enough.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
