PR017FUEL 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: Engine stopped and ignition on
The fuel flow value must be:
PR017 = 0 mg/st (ignition on).
In the event of a fault, consult the interpretation of DF897 Pump pressure regulator circuit.
Conformity check with the engine running and engine coolant temperature > 80°C
Engine running: PR017 = PR157: Fuel flow setpoint.
In the event of a fault, refer to the interpretation of fault DF897.

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:
•3LX between components 120 and 1032,
•3LY between components 120 and 1032,
•3LZ between components 120 and 1032.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
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:
View parameter PR038 Rail pressure.
– If the pressure is below 90 bar, the sensor is in order.
– If the pressure is above 90 bar, contact the Techline.

PR063FUEL TEMPERATURE
PARAMETER
DEFINITIONThis parameter indicates the fuel temperature in °C.
NOTESThere must be no present or stored faults.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– after a customer complaint (e.g. lack of power).
Use the Technical Note Wiring Diagram, Laguna II ph2, Vel Satis ph2, Mégane ll
ph2, Scénic ll ph2, Espace IV ph2.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
The fuel temperature value must be between:
– 30°C < PR063 <90°C
PR063 = 100°C (default value).
In the event of a fault, consult the interpretation of fault DF098 Fuel temperature sensor circuit.
