The fault is declared present or stored after an attempt to
start or after starting, with the engine cold, several hours after
the last trip (the difference in the coolant temperature from the
last engine stop and the present attempt to start must be at
least 60°C).
Check the condition of the rail pressure sensor connector (see Wiring Diagram Technical Note, Laguna II ph2,
Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 1032).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check that there are no external diesel leaks from the high pressure fuel circuit.
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 if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
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.
If the fault is still present, contact the Techline.

NOTESIMPORTANT:
Please observe the cleanliness guidelines and safety advice.
Use the Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2, Espace IV

Check that there is no water in the fuel filter.
Bleed the fuel filter and the low pressure diesel circuit if necessary.
Start the engine and wait at least 1 minute to confirm the repair.
If the fault was stored but not present, carry out a road test (see Note).
If the fault is still present:
Check the continuity and absence of interference resistance on the following connection:
•3WT between the components 120 and 414.
Check the + 12 V after relay supply to the water detection sensor on the following connection:
•3FB of component 414.
Check that the earth is in order on connection NT or M of component 414.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Start the engine and wait at least 1 minute to confirm the repair.
If the fault is still present, check the conformity of the fuel used:
– Check that the fuel tank has been filled correctly.
–Run Test 12 Fuel conformity check.
– If the diesel fuel is not correct:
– Replace the diesel fuel.
– Change the diesel filter.
– Bleed the low pressure diesel circuit.
