2.14 Sensors and switches

2.14.1 Fuel filter water detection sensor
(optional)
The water presence sensor in the fuel filter
serves to indicate the presence of water in
the fuel.
The sensor closes the electrical circuit
and the warnin lamp in the panel board
switches on the dashboard of the car on
which the motor is mounted.
Water, if present in the fuel, because of its
greater specific weight separates and
settles in the lower part of the filter
where there is a drain plug.
Gently loosen the water drain plug without
removing it and spill out the water if
present. Re-tighten the water drain plug H
as soon as the fuel spills.
2.14.2 Oil pressure switch
Oil pressure switch N is assembled on the
crankcase.
It is a N/C sensor, calibrated at 0.6 bar ±
0.1 bar.
With oil low pressure the sensor closes
the electrical circuit and the warning lamp
in the panel board switches on.
2.14.3 Coolant temperature sensor connector
The sensor has the dual function of a thermometer and
thermal contact.
The coolant/thermal contact P temperature probe is
applied to the cylinder head on the side of the
thermostatic valve.
Sensor P1 or P2 (Fig. 2.29) can be assembled on the
engine:
P1 Characteristics indicated in Tab. 2.33A (blue
