Pressure sensors
The pressure sensors are used to notify the electronic control unit of the oil pressure values (reference 3, Figure 1), the
atmospheric pressure (reference 5, Figure 1) and the turbo outlet air pressure (reference 13, Figure 1).
Temperature sensors
These are NTC type sensors and are used to notify the electronic control unit of the operating temperatures of the engine coolant
(reference 1, Figure 1), the engine oil (reference 2, Figure 1), the fuel (reference 6, Figure 1) and the heat exchanger outlet air
(reference 12, Figure 1).
Rpm sensors (timing sensor)
This is an inductive type sensor and is located on the camshaft (reference 9, Figure 1).
It produces signals obtained by means of the magnetic flow lines which close through the ports in the gear fitted on the camshaft.
The signal produced and sent to the electronic control unit allows the latter to calculate the moment of injection. The sensor
should be fitted by tightening it to a torque of 28 ± 7 Nm
Engine rpm sensors
This is an inductive type sensor and is located on the engine flywheel (reference 8, Figure 1).
It produces signals obtained through the magnetic flow lines which close via the ports in the actual flywheel. The electronic control
unit uses these signals to detect the various engine speeds.
Engine oil level sensors
This is a sensor used to signal a low oil level in the sump.
