Circuit Description
The Mass Airflow (MAF) sensor measures amount of air which passes through it in a given amount of time. PCM uses this information to control fuel delivery. When the volume of air increases, current flow from MAF sensor also increases. When the volume of air decreases, current flow from MAF sensor also decreases. MAF sensor is located in left front of engine compartment, between air intake tube and air cleaner.
