FUEL FLOW
PARAMETER
DEFINITIONThis parameter indicates the fuel flow in mg/st.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on.
Ignition on: PR017 = PR157 “Fuel flow setpoint”
Conformity check with engine running, engine coolant temperature > 80°C.
Engine running: 0 < PR017 < 60 mg/st
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

Sensor electrical conformity.
Check the condition of the rail pressure sensor connector (see Wiring Diagram Technical Note, Vehicle,
component code 1032).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Vehicle, component code 120).
If one of the connectors is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring
repair, wiring: precautions for repair), repair the connector, otherwise replace the wiring.
Check the continuity and absence of interference resistance of the following connections:
– connection code 3LX,
– connection code 3LY,
– connection code 3LZ.
Between components 120 and 1032.
If any of the connections are faulty and there is a repair method (see Technical Note 6015A, Electrical wiring
repair, Wiring: precautions for repairs), repair the wiring; otherwise replace the wiring.
Check that there are no external diesel leaks from the high pressure fuel circuit.
With the ignition on and the engine stopped for over 1 minute:
Display parameter PR038.
– If the pressure is below 90 bar, the sensor is in order.
– If the pressure is above 90 bar, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

FUEL FLOW SETPOINT
PARAMETER
DEFINITIONThis parameter indicates the fuel flow setpoint in mg/st.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on.
Ignition on: 0 < PR157 < 60 mg/st
Conformity check with engine running, engine coolant temperature > 80°C.
Engine running: PR017: Fuel flow = PR157.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

RAIL PRESSURE LOOP DIFFERENCE
PARAMETER
DEFINITIONThis parameter indicates that the fuel pressure variation is the difference between the
rail pressure and the rail pressure setpoint.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on.
The value should be:
PR213 = PR008 Rail pressure setpoint – PR038 Rail pressure
In the event of a fault, consult the interpretation of fault DF007 Rail pressure sensor circuit.
Engine running, engine coolant temperature > 80°C.
The value should be:
PR213 = PR008 Rail pressure setpoint – PR038 Rail pressure
In the event of a fault, refer to the interpretation of faults DF007 Rail pressure sensor circuit and DF053 Rail
pressure regulation function.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
