MAP-Sensoren, auch bekannt als Saugrohrdrucksensoren, sind Geräte, die den Druck im Ansaugkrümmer eines Motors messen und diese Daten an das ECU (Motorsteuergerät) oder Motor-Management-System übermitteln. Die Druckdaten des MAP-Sensors werden vom ECU genutzt, um die Dichte der in den Motor einströmenden Luft zu berechnen und somit die geeignete Kraftstoffmenge für eine optimale Verbrennung zu bestimmen. Dies trägt dazu bei, die Motorleistung, Kraftstoffeffizienz und Emissionen zu optimieren. MAP-Sensoren werden üblicherweise sowohl in Benzin- als auch in Dieselmotoren eingesetzt und sind besonders wichtig bei aufgeladenen Motoren (wie turbo- oder kompressoraufgeladenen Motoren), bei denen der Ansaugluftdruck erheblich vom atmosphärischen Druck abweichen kann.<\/p>\n
