F. FUEL PRESSURE SENSOR
SPECIFICATIONS
It is fitted at the end of the of the single fuel manifold
rail and its function is to provide the injection control
unit with a feedback signal to enable it to :
- modulate the injection pressure;
- regulate the fuel injection duration.
The sensor receives a direct supply from the engine
management control unit of 5 V. The output voltage
varies in a linear fashion between 0.5 V (0 bar) and
4.5 V (1500 bar)

G. ACCELERATOR PEDAL POTENTIOMETER
CONSTRUCTION SPECIFICATIONS
The sensor is secured to the accelerator pedal; inside
it contains an axially-located shaft connected to two
potetiometers : a main one and one safety one.
Acoil spring on the shaft ensures the correct amount
of resistance to pressure while a second spring
ensures return following release.
The redundant signal reading makes it possible to
continuously monitor the plausibility of the readings
in order to guarantee complete safety whilst driving
even if there is a failure.
