Function
The intake manifold pressure deforms the membrane which acts on a potentiometer. This alters the resistance value of the potentiometer and influences
the voltage signal in such a way that it serves the ME-SFI [ME] control unit as information about the intake manifold pressure.
The pressure sensor measuring range lies between 0.1 and 1.2 bar.
Example:
Intake manifold pressure

1.2 bar
4.5 V
0.8 bar
3.3 V
0.1 bar
0.5 V
