high or very high injector pressure).
Check the connection and condition of the accelerometer connector, component code 146.
Check the connection and condition of the injection computer connector, component code 120 and the shielding
of the sensor on connection TB1.
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A (Renault) or Technical
Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the connector, otherwise
replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
●3DQ between components 120 and 146,
●3S between components 120 and 146.
If the connection(s) are faulty and if there is a repair procedure (see Technical Note 6015A (Renault) or

NOTESFault finding procedure application conditions:
The fault is declared present after the engine has been started.
Priorities when dealing with a number of faults:
– DF057 Water in diesel fuel detector circuit,
Special note:
If the fault is present, the level 1 warning light comes on or the water present in
diesel fuel warning light comes on (if present on the instrument panel and if
configured in injection).
Use the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2 or Kangoo VLL.
Check for the presence of water in the diesel filter; if water is present, bleed the diesel filter.
If there is a great amount of water, run the first part of Test 13: Diesel fuel conformity check (Is the fuel cloudy
or does it separate into 2 parts?)
Check the connection and condition of the connector of the water in diesel fuel sensor, component code 414.
Check the connection and condition of the injection computer connector, component code 120.
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A (Renault) or Technical
Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the connector, otherwise
replace the wiring.
Check for a voltage between 13V and 14V (with the engine running) and between 11.5 V and 12.5 V (with the
ignition on and engine stopped) on connection 3FB (or 3FB2, or 3FBA) on the connector of the water in diesel
fuel sensor, component code 414.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A (Renault) or Technical

A) Make sure the water in diesel fuel detection sensor is properly connected.
– If not, clear the fault,
– Carry out a road test (speed >12 mph (20 km/h) and engine speed >1200 rpm) for more than 30 seconds.
– If the fault does not reappear, end of fault finding procedure.
– If the fault reappears, go to step B.
B) If the sensor is properly connected:
– Bleed the diesel filter unit (see MR 388 (Logan/Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2) or
MR 374 (Kangoo VLL), Mechanical, 13A, Fuel supply, Diesel filter: Removal - Refitting).
– Clear the fault.
– Carry out a road test (speed >12 mph (20 km/h) and engine speed >1200 rpm) for more than 30 seconds.
If the fault does not reappear, end of fault finding procedure.
C) If the fault recurs:
Check the insulation and continuity of the following connections:
–3WT between components 120 and 414,
–M (or 3WU) between components 120 and 414.
If the connection or connections are faulty and if there is a repair procedure (see Technical Note 6015A (Renault)
or Technical Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the wiring,
otherwise replace it.
If none of these checks reveal any faults:
– Replace the water detection sensor (see MR 388 (Logan/Sandero), MR 451 (Duster), MR 423 (Thalia 2/
Symbol 2) or MR 374 (Kangoo VLL), Mechanical, 13A, Fuel supply, Diesel filter: Removal - Refitting).
– Clear the fault.
– Carry out a road test (speed > 12 mph (20 km/h) and engine speed > 1200 rpm) for more than 30 seconds, to
confirm the repair.
Note:
When the water level in the fuel filter unit is below the sensor's electrodes, some driving conditions (turning,
inclines) may cause the injection fault warning light to come on erroneously (the sensor's off-centre position in the
fuel filter unit, combined with the driving condition, shows water detection, and hence the light comes on).
If the fault is still present, contact the Techline.
