Fundamentals of Map Sensors

What is a Map Sensor?

Definition and Purpose:

A map sensor is a gadget that figures out the total air pressure in an engine’s intake manifold. Its re-adings are sent to the engine control module (ECM). The ECM uses these to figure out how dense the air is and tune the engine’s workings. The main job of a map sensor? It’s to help the engine work as best as it can. It helps balance the air and fuel mix, maximize power and keep emissions to a minimum.

Working Principle:

Map Sensor 6.7 Powerstroke typically employ a pressure-sensitive diaphragm or piezoresistive element that translates changes in air pressure into electrical signals.
