ACDelco GM original equipment manifold absolute pressure sensors measures the intake manifold pressure, and is a GM-recommended replacement for your vehicle's original component. If the reference voltage and the grounding are correct, check the signal wire between the MAP sensor and the onboard controller. The sensor generates a signal that is proportional to the amount of vacuum in the intake manifold. It preceded the mass airflow sensor and was much less efficient. The MAP sensor measures the absolute pressure inside the intake manifold of the engine. With a running engine, intake manifold vacuum usually runs around 18 - 20 “Hg (inches of mercury). 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). This is because the MAP sensor measures “absolute” pressure, based on a perfect vacuum, rather than atmospheric pressure. Vehicle Engine Electrical Inspection Cost, The statements expressed above are only for informational purposes and should be independently verified.

A manifold absolute pressure sensor, commonly abbreviated to MAP sensor, is used in some fuel injection engines to determine the pressure in the intake manifold, and then provides a signal on engine load to the vehicle's engine control unit (ECU).The ECM uses this data to calculate air density and determine the engine's air . The sensor is used in electronic control systems for fuel consumption of an engine. Connect a vacuum pump to the MAP sensor’s vacuum hose. If voltage sharply rises to its maximum value when the accelerator is pressed, and quickly falls to the minimum when accelerator is released - MAP sensor is working properly. If they are correct under suspicion falls the controller. • Replaces Harley Davidson® OE # 32316-99, 32424-99, 32424-98, 32416-10, and 32417-10. ECU estimates the data from the MAP sensor values as: "Absolute Pressure" = "Atmospheric pressure" - "manifold pressure”.By using the speed/density method, the onboard controller calculates the fuel mixture composition depending on the signal of MAP and engine speed. The various pressure sensors provide instant pressure data to the electronic control unit (ECU) of an engine. technically, manifold pressure is the pressure above an absolute vacuum and boost pressure is positive compressed pressure above atmospheric usually the result of a turbo or supercharger. There are a few things that can cause vehicles fuel trims to vary from normal. As you may know, the intake manifold is responsible for distributing the air and fuel mixture from the internal combustion chamber into each cylinder. You’re seeing this ad based on the product’s relevance to your search query. This MAP sensor is mounted directly to the intake manifold, but others might be connected by a hose. -- Check the accuracy of the external MAP sensorTerms under which checks are carried out - the engine not started and vacuum is provided with a vacuum pump. Therefore there is no risk of MAP sensor fuel penetration and contamination of the diaphragm, and therefore a special trap is not used.When the MAP sensor is used as a separate component, inexpensive maintenance could be achieved. Turn off the vacuum pump. When MAP sensor is built into the onboard controller, possible replacement of the MAP will require the replacement of the whole controller. CLICK HERE.
