MAF Frequency

Range (Frequency In Hertz)
The MAF produces a frequency as it measures airflow entering the engine. The VCM detects this frequency on the signal circuit and converts it into a grams per second (g/s) of airflow scale. This raw frequency can be displayed by the scan tool as it is detected by the VCM.
