HOW DOES IT WORK
The Manifold Absolute Pressure (MAP) sensor signal is electrically used in a similar way to the use of Mass Air Flow (MAF) sensor signal
(although internally it is built differently). It takes a 5 volt power from the ECM or ECU (Engine Control Unit or Module) computer, and
returns a lower signal in accordance with the vacuum in the engine. A higher output voltage means lower engine vacuum, which is then
calculated as “more fuel is needed”. Lower output signal indicates higher engine vacuum, which requires less fuel. It's not just fuel control.
The MAP sensor signal gives the computer a dynamic indication of engine load. The computer then uses this data to control not only fuel
injection, but also gear shift and cylinder ignition timing.
