Restore parameters PR063 Fuel temperature and PR064 Coolant temperature.
Fuel temperature reference value when operating at idle speed is between 60 °C and 80 °C.
The coolant temperature reference value is between 80 °C and 90 °C.
Note:
– when the fuel temperature is above 120°C, the maximum rail pressure is reduced to protect the plastic pipes,
– when the coolant temperature is above 100°C, the maximum rail pressure is reduced to protect the engine.
Are the fuel and coolant temperatures within the
reference value range?
YES
NOCheck the coolant temperature (see the
interpretation of DF001 Coolant
temperature sensor circuit) and fuel

Start the engine and let it idle.
An unusual combustion noise may be heard.
Check the rail pressure using parameter PR038
Rail pressure.
At idle speed: rail pressure between 190 and
210 bar
2000 rpm: rail pressure between 440 and
560 bar
3000 rpm: rail pressure between 380 and
480 bar
4000 rpm: rail pressure between 470 and
570 bar
Are the rail pressure values correct?
NO
Replace the pump (see Replacement of
components).
Note:
Deviations from the reference values may occur in the rail pressure regulation circuit because of wear, clogging or
faulty sensors or actuators.
These deviations can only be compensated for by the pressure regulator within certain limits.
One consequence of this is that the rail pressure may be regulated so that it is too low or too high or it fluctuates.
YESRail pressure regulation circuit correct.
