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.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is considered present when the engine is running.
Priorities when dealing with a number of faults:
– Deal with all the other faults before fault DF859
Special notes:
This fault is activated when the injectors have not been reset for 1800 miles
(3000 km).
Leave the vehicle to run at idle speed until the engine is warm.
When the engine is warm (PR064 COOLANT TEMPERATURE above 77°C), carry out the following test drive:
– Drive at a speed of up to 30 mph (50 km/h) and change into 5th gear.
– Stay in this gear and perform 8 accelerations from 30 mph (50 Km/h) to 54 mph (90 Km/h).
– At the end of driving: without switching off the ignition, allow the vehicle to run at idle speed for at least
10 minutes.
– Switch off the ignition, and wait 30 seconds.
– switch on the ignition, check that the fault is stored and clear the fault.
