NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after a series of full-load/no-load actions on the
accelerator pedal.
Special notes:
Turbocharging, passenger compartment heating resistor activation and the cruise
control/speed limiter are not authorised.
If CO.0, CC.1 or 1.DEF is present the level 1 warning light is lit.

potentiometer and the engine torque is limited.
Use bornier Elé. 1681 or Elé. 1590 for all operations on the computer connectors.
Priorities when dealing with a number of faults:
Deal with fault first if it is DF011 Sensor feed voltage no. 1 first if it is present or
stored.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.

NOTESPriorities when dealing with a number of faults:
If fault DF009 Pedal potentiometer circuit gang 2 is
present at the same time, check that the pedal sensor
connector is connected correctly.
Check the pedal potentiometer connections.
Check the injection computer connections.
Repair if necessary.
Check the continuity and insulation to earth of the following connections:
– connection code 3KW,
– connection code 3LR,
between components 120 and 921.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Measure the resistance of the pedal potentiometer on gang 1 between connections 3LR and 3LT.
