Difference Between a MAF and MAP Sensor Explained

+

A faulty MAP sensor affects engine performance but can also affect transmission''s shift timing. This is because the PCM uses this signal as an indication of engine load. Another sensor that indicates engine load and that also affects shift timing is the MAF sensor. A (MAF) mass air flow sensor measures the volume of air passing through the air ...

Sep 20, 2018· Most modern EFI engines have a Mass Air Flow (MAF) sensor located in the air intake of the engine. This is the device that measures how much air is coming into the engine so that the computer can determine how much fuel it needs to inject. While the MAF sensor does not directly measure the actual flow rate of air, it measures the density.

Mass Air Flow Sensors vs Manifold Air Pressure Sensors ...

+

A MAF sensor isn’t the only way for the ECU to calculate engine load and a common alternative is to use a manifold air pressure sensor (MAP sensor) instead. A MAP sensor measures the air pressure or vacuum in the intake manifold and the mass of air entering the engine can be calculated from this using the ideal gas law.

MAP vs. MAF vs. IAT Sensors | 1A Auto

+

MAF is an acronym for "mass air flow." Unlike IAT sensors, MAF sensors measure air volume with temperature at once. Remember, the MAP sensor above measured intake manifold pressure / vacuum and then estimated air volume with computer software. An MAF actually measures real air volume so that the computer doesn''t need to guess what it might be.
