The Mass Air Flow Sensor (MAF) is used in Cadillac DeVille cars to enhance the functionality of the engine since it is in charge of measuring the amount of air that is required in the engine. This information is then sent to the Powertrain Control Module which alters the pulse of fuel injector to provide the correct a/f mixture. There are several varieties of Mass Air Flow Sensor, including Vane Meter (VAF) and Hot Wire sensors; their working principles to measure airflow differ. The VAF sensor employs a spring mounted vane to detect the flow while the Hot Wire measures the change in current in a heated wire that is placed in the airflow. But both of them, including the Hot Wire sensor which is very accurate, can be damaged by contaminants and less accurate. The MAF sensor has to be frequently checked to ensure that it works properly because when the MAF sensor fails to work well, it causes; poor acceleration, stalling, and wrong air-fuel ratios.
