NOTESPriority when dealing with a number of faults:
First deal with fault DF003 Atmospheric pressure sensor
circuit.
Conditions for application to a stored fault:
The fault is declared present after the ignition has been
switched on for 1 second, with a warm engine and when
the vehicle is stationary.
If the fault is present:
– the EGR function is inhibited,
– the turbocharging pressure value is in safe mode, PR041
Turbocharging pressure sensor = 1000 mbar,
– turbocharging is cut off.
– the maximum torque supplied by the engine is restricted.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and
KANGOO II Wiring diagrams Technical Note.
Check the connection and condition of the turbocharging pressure sensor connector, component code1071
and the injection computer, component code120 (see MR 392, 385, 364, 370 and 417, Mechanical, 13B,
Diesel injection, Diesel injection computer: Removal - Refitting).
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(s); otherwise, replace the wiring.
With the ignition on, check for the presence of + 5 V on connection 3LQ and check for an earth on connection
3LN on the turbocharging pressure sensor, component code 1071.
If the connection(s) 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.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–3LQ between components 1071 and 120,
–3LP between components 1071 and 120,
–3LN between components 1071 and 120.
If the connection(s) are faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the connections are correct, replace the turbocharging pressure sensor
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.

NOTESPriorities when dealing with a number of faults:
If one or more of the following faults are present at the same time:
–DF008 Pedal potentiometer circuit gang 1, check that the pedal sensor
connector is connected correctly.
–DF004 Turbocharging pressure sensor circuit, check that the turbocharging
pressure sensor connector is connected correctly.
–DF049 Refrigerant sensor circuit, check that the refrigerant sensor connector is
connected correctly.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the ignition has been switched on.
Special notes:
If the fault is present:
– The cruise control/speed limiter is deactivated.
– Power is restricted.
–The level 1 warning light is lit.
–The OBD warning light is illuminated.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
The sensors connected to supply no. 2 are:
–Accelerator pedal potentiometer gang 1 sensor, component code 921,
–Turbocharging pressure sensor, component code 1071,
–Refrigerant pressure sensor, component code 1202.
To locate the potentially defective sensor and/or connection, disconnect one of these sensors and then check
whether the fault becomes stored.
If the fault is still present, start the operation again with each sensor (one by one).
(Wait several seconds between each disconnection to allow the computer to detect the fault)
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 displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
