Manifold Pressure Differential Sensor: Description and Operation
DESCRIPTION
The manifold differential pressure sensor converts air pressures in the intake manifold plenum into voltage signals and send them to the engine
control module.
The engine control module monitors the EGR system using this signals and generates the diagnostic trouble code if there is an abnormality in the
EGR system.
OPERATION
5V of power is supplied to the manifold differential pressure sensor from the engine control module, and the sensor circuit ground is located in the
engine control module.
The manifold differential pressure sensor output voltage is proportioned to the intake manifold plenum pressure and sent to the engine control
module.
