Fuel pressure sensor task	Detect fuel system pressure and conduct a corresponding voltage signal to the fuel pump control unit (N118).
Fuel pressure sensor design	Inductive measuring cell out of coil, movable anchor and electronics
Fuel pressure sensor function	With increasing fuel pressure the anchor moves further into the coil. An electronics detects the inductivity of the measuring cell and gives a signal (approx. 0.5 V at 0 bar; approx. 4.5 V at 9 bar).
