The manifold absolute pressure sensor (MAP sensor) is one of the sensors used in an internal combustion engine's electronic control system. Engines that use a MAP sensor are typically fuel injected. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engine's electronic control unit (ECU).
On vehicles so equipped, this alternative involves the use of a manifold absolute pressure, or MAP, sensor. The MAP sensor measures pressure in the engine's inlet manifold. When coupled with data regarding the engine's revolutions per minute, or RPM, and a table of volumetric efficiency over the operating range of the engine, the MAP sensor can ...
It was also the first with a map display. [5] 1981: Navigation computer on the Toyota Celica (NAVICOM). [7] 1983: Etak was founded. It made an early system that used map-matching to improve on dead reckoning instrumentation. Digital map information was stored on standard cassette tapes. [8]
Delco ECU used in General Motors vehicles built in 1996. An engine control unit (ECU), also called an engine control module (ECM), [1] is a device that controls various subsystems of an internal combustion engine.
MAF sensor in a 2006-2015 automotive diesel engine. A mass (air) flow sensor (MAF) is a sensor used to determine the mass flow rate of air entering a fuel-injected internal combustion engine. The air mass information is necessary for the engine control unit (ECU) to balance and deliver the correct fuel mass to the engine. Air changes its ...
