Special notes:
If fault DF008 is present: the engine speed is maintained above 1000 rpm (normal idle
speed with the brake pedal depressed) and the level 1 warning light comes on
(except 3.DEF).
If faults DF008 and DF009 Pedal potentiometer circuit gang 2 are present: engine
speed fixed at 1300 rpm, level 1 warning light lit.

NOTESNone.
Disconnect the injection computer connector, component code 120 and the pedal potentiometer connector,
component code 921.
Check the insulation, continuity and the absence of interference resistance of the following connections:
●3LS between components 120 and 921,
●3LW between components 120 and 921.
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.
If the fault is still present, replace the pedal potentiometer (see MR 388 (Logan/Sandero), MR451 (Duster), MR
