Manifold Pressure/Vacuum Sensor: Description and Operation
INTAKE MANIFOLD PRESSURE SENSOR
The intake manifold pressure sensor is attached to the top of the throttle body, and continuously sends to the engine control module (ECM) voltage
signals that are proportional to intake manifold absolute pressures. The ECM controls the fuel injection and ignition timing based on the intake manifold
absolute pressure signals in addition to other signals from many sensors and other control modules.
