NOTESPriorities when dealing with a number of faults:
– DF001 Coolant temperature sensor circuit,
– DF002 Air temperature sensor circuit,
– DF003 Atmospheric pressure sensor circuit,
– DF098 Fuel temperature sensor circuit,
A fault on one of these sensors could lead to incorrect fault finding on the
accelerometer.
Conditions for applying the fault finding procedure to a stored fault:
The fault is considered present when the engine is running.
Special notes:
Use the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2 or Kangoo VLL.
Check the conformity of the injectorsfitted to the vehicle in relation to the type of vehicle and engine number (low,
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
Technical Note 9804A (Dacia), Repairing electrical wiring, Wiring: Precautions for repair), repair the wiring,
otherwise replace it.

Conditions for applying the fault finding procedure to a stored fault:
The fault is considered present when the engine is running.
Use the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2 or Kangoo VLL.
Check the connection and condition of the flow actuator (IMV) connector, component code 1105.
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 the insulation, continuity and the absence of interference resistance on the following connection:
●3HI between components 120 and 1105.
If the connection is 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.
Measure the resistance between connections 3HI and 3FB (or 3FB2) of the flow actuator, component code 1105.
If the resistance of the flow actuator is not between: 4.8 < X < 5.8 at 20°C, replace the flow actuator (see MR
388 (Logan/Sandero), MR 451 (Duster), MR 423 (Thalia 2/Symbol 2) or MR 374 (Kangoo VLL), Mechanical,
13B, Diesel injection, Flow actuator: Removal – Refitting).
Check the presence and conformity of fuel in the tank.
Apply test 13 Diesel fuel conformity check.
Run test 1 Low pressure circuit check.
If the fault is still present, run test 6 High pressure system check.
