VDO 5WK9613Z Mass Air Flow Sensor

The VDO 5WK9613Z Mass Air Flow Sensor is a precision engine management component designed to accurately measure the volume and density of air entering the engine. This sensor enables the engine control unit (ECU) to calculate and deliver the optimal fuel-to-air ratio for efficient combustion, maximizing engine power and fuel economy.

Key Features:

• Black plastic housing with durable construction
• Male blade terminal connector with 4 terminals
• 12-volt operation for reliable performance
• Direct replacement for OEM part numbers 1110940148 and A1110940148
• Compatible with Mercedes-Benz vehicles equipped with 111.983 engine code

Symptoms of a Failing MAF Sensor:

• Poor fuel economy and reduced engine efficiency
• Engine hesitation or jerking during acceleration
• Rough idling or engine stalling
• Check engine light illumination
• Difficulty starting the engine

When a mass air flow sensor fails, it can no longer accurately measure the air entering the engine, causing the ECU to provide incorrect fuel delivery. This results in excessively rich or lean running conditions that negatively impact performance. VDO has provided OE-quality electrical and electromechanical components for nearly a century, ensuring this replacement sensor meets or exceeds original equipment specifications for fit, form, and function.
