The difference between MAF sensor and MAP sensor
Model: (Various brands) Various
In this video we try to clarify once and for all the difference between MAF sensor and MAP sensor: the MAF sensor is the airflow meter, which measures the air mass, the MAP sensor is the "intake manifold pressure sensor". In naturally aspirated gasoline engines it had the function of the airflow meter, so it sensed the air mass, but without load. In diesel engines it has the function of the boost pressure sensor. If this sensor has problems, the user will notice it, because the vehicle starts jerking, power could decrease, the engine malfunction light comes on and the car goes into recovery mode, or it may stop the injection. There could be a broken wiring, or a poor communication with the ECU, or - especially in diesel engines - it could get dirty.
