PARTICLE FILTER PRESSURE SENSOR
STATUS DEFINITIONACTIVE: This status indicates that the particle filter electric fuel pump is active.
INACTIVE: This status indicates that the particle filter electric fuel pump is not active.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Only for vehicles equipped with a particle filter.
Conformity check with the engine stopped and the ignition on, or engine running, and engine coolant
temperature > 80°C
ACTIVE
INACTIVE
The status is ACTIVE during the particle filter regeneration phase.
If there is a fault, consult the interpretation of fault DF1004 Electric fuel pump control
relay circ**.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

AIR FLOW
PARAMETER
DEFINITIONThis parameter indicates the inlet air flow in mg/st.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
No faults must be present.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– or after a customer complaint (lack of power, smoke etc.).
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
Diagrams Technical Notes.
Sensor electrical conformity
Check the air inlet circuit (from the air filter inlet to the inlet manifold, run test 10 Air line at the turbocharger):
– air filter unit inlet not blocked and filter not clogged,
–visual inspection only, use ALP2 The engine does not start or starts with difficulty,
– oil vapour recirculation circuit connected correctly,
–absence of leaks or blockages in the low and high pressure air circuits: ducts, presence and tightness
of the mounting clips, mounting of the turbocharging pressure sensor, exchanger, etc.
– check that the damper valve is not jammed shut (except Vdiag 4C).
Carry out the necessary repairs.
Check the electrical conformity of the air flow sensor:
Check the + 5 V supply to the air flowmeter.
– connection 3KJ of component 799.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
