Mass Air flow Sensor (MAF): how it works, symptoms ...

Jul 09, 2021· Mass Airflow Sensor (MAF) readings of a 4-cylinder engine at different RPMs. Often mass air flow sensor readings are measured at idle, 1,000 RPM, 2,000 RPM and 3,000 RPM. A contaminated or bad air flow sensor will, in most cases, show lower air flow readings than a known good one. In some rare cases a bad sensor may show higher readings.

Mass Air Flow Sensor/Meter | O'Reilly Auto Parts

The mass air flow (MAF) sensor measures the mass flow rate of air entering the engine. This information is then used by the ECU to calculate the amount of fuel needed for the correct air-fuel mixture. If the mass air flow sensor has failed or needs to be cleaned, this can cause especially rich or lean fuel mixtures.
