2.DEF : Sensor reference voltage too high
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after carrying out a road test or after several attempts at
starting the engine.
Special notes:
If the fault is present:
–the cruise control/speed limiter function is inhibited,
–turbocharging is inhibited,
–the engine speed is limited,
–the level 1 warning light is lit,
–the OBD warning light will come on after three consecutive driving cycles (starting
+ 5 seconds + switching off the ignition and waiting 1 minute).
Use bornier Ele. 1681 or Ele. 1590 for any operation on the injection computer
connectors.
WARNING
This fault may appear if the wiring harness has been damaged.
Follow the procedure described in the Wiring Check in the Introduction.
This check enables the condition and the conformity of the engine wiring harness to be checked.
1.DEF
2.DEF
NOTESPriorities when dealing with a number of faults:
If fault DF008 Pedal potentiometer circuit track 1 is
present at the same time, check that the sensor is connected
correctly.
In the event of the simultaneous presence of fault DF004
Turbocharging pressure sensor circuit, check that the
turbocharger pressure sensor circuit connector is connected
correctly.
The sensors connected to supply no. 1 are:
–Turbocharger pressure sensor.
–Accelerator pedal potentiometer sensor, gang 1.
To locate a faulty sensor and/or connection, disconnect one of these sensors then check whether the fault
becomes stored.
If the fault is still present, start the operation again with the other sensor.
(Wait a few seconds after each disconnection so that the computer can carry out the check).
If the fault is stored after a disconnection, replace the faulty sensor or repair its connection.
Clear the faults created by the multiple disconnections.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

(Wait a few seconds after each disconnection so that the computer can carry out the check).
If the fault is stored after a disconnection, replace the faulty sensor or repair its connection.
Clear the faults created by the multiple disconnections.
Check the condition of the connector of the EGR valve position sensor, component code 1460, of the accelerator
pedal potentiometer sensor gang 2, component code 921 and of the refrigerant pressure sensor, component code
1202.
Check the 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, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
AFTER REPAIRDeal with any faults.
