Mercedes Sprinter Mass Air Flow Sensor – Bosch OEM | OM642 3.0L | #0000943448 (2010–2022)

DESCRIPTION:

A failing mass air flow sensor is one of the most common causes of rough idle, black smoke, poor fuel economy, and reduced power on a Sprinter diesel. The MAF sensor is the engine's primary source of intake air data — when it reads incorrectly, the ECU can't calculate the right fuel delivery, and performance suffers across the board. This is the genuine Bosch OEM MAF sensor for 2010–2022 NCV3 and VS30 Sprinters with the OM642 3.0L V6.

What This Part Does

The mass air flow sensor measures the volume and density of air entering the engine and sends that data to the ECU in real time. The ECU uses this data to calculate precise fuel injection quantities for every combustion event. A contaminated, drifting, or failed MAF sensor throws off this calculation — leading to rich or lean running conditions, elevated emissions, rough idle, hesitation, and in some cases, limp mode activation.

Common Symptoms of a Failing MAF Sensor

• Black or excessive smoke from the exhaust
• Rough or unstable idle
• Reduced power or sluggish throttle response
• Poor fuel economy
• Check engine light with MAF or air mass related fault codes (P0100–P0104)

Critical Fitment Note — 2010+ vs. Earlier Sprinters

This sensor (0000943448) is correct for 2010–2022 Sprinters only. Earlier 2007–2009 NCV3 Sprinters require a different MAF sensor — part number 0000943248 / Bosch 0281002896. Using the wrong sensor will result in improper readings and ongoing fault codes. Always verify your model year and VIN before ordering.
