A vacuum gauge is used to measure the pressure in a vacuum. Application for car is at the MAP sensors. Most fuel injected cars uses MAP sensors to provide instantaneous manifold pressure information to the engine's electronic control unit (ECU). The data is used to calculate air density and determine the engine's air mass flow rate, which in turn determines the required fuel metering for optimum combustion. A fuel-injected engine may alternately use a mass airflow sensor (MAF sensor) to detect the intake airflow.
