Mass Air Flow Meter Sensor - Mercedes-Benz - 5WK98101

The MAF sensor measures the volume and density of air entering the engine. This data is sent to the engine control unit (ECU) to determine the correct amount of fuel to inject for optimal combustion.

Common symptoms include a rough idle, hesitation during acceleration, poor fuel economy, increased exhaust emissions, stalling, and the illumination of the Check Engine Light.

While physically possible, the warranty for this part is only valid if installed by a qualified mechanic. You will need to provide proof of professional installation.

Ensure the electrical connector is securely plugged in. Verify the sensor is the correct part for your vehicle model and year. Have diagnostic trouble codes (DTCs) read and cleared by a mechanic. Confirm the MAF sensor was installed by a qualified professional as required for warranty.

Double-check that the MAF sensor was installed correctly and all air intake connections are sealed. A dirty air filter or other issues in the air intake system could also be contributing factors. Consult a qualified mechanic to diagnose further.

Ensure you are using the correct part number for your vehicle. Verify no obstructions are present in the air intake housing. If resistance is met, do not force the installation; consult your mechanic.
