If the information is incorrect, then an incorrect amount of fuel will be put into the engine causing it to run either too lean or too rich.

This will jeopardize the entire internal combustion process because the engine won’t receive the proper amount of fuel from the injectors. If your mass air flow sensor ever goes bad or malfunctions for some reason, it will send the wrong information about the airflow mass to the engine control unit.
