PRECAUTIONS/RISKS
The main recommendation regarding the system is:
Never electrically disconnect the injectors with the engine running.
The piezoelectric technology used for the injector system means that the injectors receive a control pulse to open
and another control pulse to close. If the injector is disconnected between these 2 pulses while the engine is
running, i.e. during the actual injection process, the injector will remain open long enough to create very
unfavourable thermodynamic conditions in the cylinder(s) or generate hydraulic pressure which may result in
engine damage. Tool fault Associated DTC Diagnostic tool title

NOTESPriorities when dealing with a number of faults:
If one or more of the following faults are present at the same time:
–DF009 Pedal potentiometer circuit gang 2, check that the pedal sensor
connector is connected correctly.
–DF007 Rail pressure sensor circuit, check that the rail pressure sensor connector
is connected correctly.
–DF056 Air flow sensor circuit, check that the air flow sensor connector is
connected correctly.
–DF209 EGR valve position sensor circuit, check that the EGR valve position
sensor connector is connected correctly.
–DF1003 Particle filter differential pressure sensor circuit, check that the
connector of the particle filter differential pressure sensor 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 lit.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
The sensors connected to supply no. 1 are:
–rail pressure sensor, component code1032,
–accelerator pedal potentiometers gang 2 sensor, component code921,
–air flowmeter sensor, component code799,
–EGR valve position sensor, component code 1460.
–particle filter differential pressure sensor, component code 1290.
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.
