11-2 Intake manifold pressure sensor
Function:
Monitor absolute pressures (kPa) in the intake
manifolds; provide information about the engine
load.
Rang of pressures monitored: 10~115kPa
Principle:
Due to any change in the intake manifold's pressures causing deformation of a pressure sensor's diaphragm, the
piezo-resistance effect makes resistance changed and further developed to be signals (voltages) proportional to
pressures under a processor chip's functions.
