Question

Quizplus · Accepted Answer

An intake manifold vacuum is used to sense the load on an engine. The vacuum signal provides information about the engine's load and is used by various systems, such as the brake booster and EGR valve, to adjust their operation accordingly. The powertrain and crank angle are not directly related to sensing the engine load, while the battery provides electrical power but does not provide information about the engine's operation.
