Manifold Pressure/Vacuum Sensor: Description and Operation

PURPOSE\OPERATION
The manifold differential pressure sensor converts air pressures in the intake manifold plenum into Voltage signals and inputs it to the powertrain control module. The powertrain control module monitors the EGR system using this signals and generates the diagnostic trouble code if there is an abnormality in the EGR system.
5V of power is supplied to the manifold differential pressure sensor from the powertrain control module, and the sensor circuit ground is located in the powertrain control module.
The manifold differential pressure sensor output Voltage is proportioned to the intake manifold plenum pressure and sent to the powertrain control module.
