4.7.2 SENSORS
Driving shaft position sensor (2)
Location: in the flywheel cover (10)
The sensor detects the number of teeth present on the
rotor.
The engine speed and the position of the driving shaft
are calculated based on the signals emitted.
Camshaft position sensor (11)
Position: in the front cylinder head (12).
The signal is sent out through the identification of a
tooth present on the exhaust camshaft sprocket.
This signal makes it possible to detect the current en-
gine stroke.
Intake pressure sensor (13)
Location: in the intake manifold.
The pressure measured in the induction pipe is con-
verted into a voltage signal.
Moreover, the injection time also depends on the induc-
tion pipe pressure, especially when the throttle valve
opening angle is limited (during idling).
Throttle valve potentiometer (3)
Location: on the throttle body (14).
The throttle valve potentiometer measures the position
of said valves and acts as the main parameter in deter-
mining the injection time and ignition angle.
