PR383WEIGHT OF SOOT IN PARTICLE FILTER
PARAMETER
DEFINITIONThis parameter indicates the weight of soot in the particle filter in g.
NOTESNone.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
The value of the weight of soot in the particle filter must be:
PR383 < 56 g.
If the weight is greater than 56 g:
For all Vdiags (except 18): carry out an After-Sales regeneration. Run command SC017 Particle filter
regeneration and follow the procedure (see Interpretation of commands).
For Vdiag 18:
Reprogram the computer in Vdiag 1C.
Then apply the procedure corresponding to Vdiag 1C.
In the event of a fault, refer to the interpretation of fault DF315 Particle filter diff* pressure sensor.

PR414PARTICLE FILTER DIFF* PRESSURE
PARAMETER
DEFINITIONThis parameter indicates the particle filter differential pressure in mbar.
NOTESNone.
Conformity check: Engine stopped and ignition on
The value of the particle filter differential pressure must be between:
- 1 mbar < PR414 < 1 mbar
In the event of a fault, refer to the interpretation of fault DF315 Particle filter diff* pressure sensor.
Conformity check with the engine running and engine coolant temperature > 80°C
The value of the particle filter differential pressure must be between:
10 mbar < PR414 < 100 mbar
In the event of a fault, refer to the interpretation of fault DF315.

Perform the following road test (looking for a loss of power when accelerating under full load):
– in the highest gear ratio, accelerate fully,
– lift your foot off the accelerator pedal completely for at least 2 seconds,
– accelerate fully again,
– release the accelerator pedal completely,
– accelerate slightly.
If the loss of power was not noted during slight acceleration and if there was a loss of engine power during each
acceleration at full load, replace the diesel fuel injector return rail and its overpressure valve (see MR364
(Mégane II ph2), MR370 (Scénic II ph2), MR 395 (Laguna II ph2), 402 (Vel Satis ph2), 405 (Espace IV ph2)
Mechanical, 13B, Diesel injection, Diesel injector fuel return rail: Removal - Refitting).
Check the connection and positioning of the differential pressure sensor (see MR 395 (Laguna II ph2), 402 (Vel
Satis Ph2), 405 (Espace IV ph2), 364 (Mégane II ph2), 370 (Scénic II ph2) Mechanical, 19B, Exhaust, Particle
filter pressure sensor: Removal - Refitting).
Check the conformity of the accelerator pedal position sensor, the brake pedal sensor, the atmospheric pressure
sensor, the exhaust gas recirculation valve, and the damper valve (see Interpretation of statuses and
parameters).
Check the consistency of the signal from the air flowmeter, the engine coolant temperature sensor, the fuel
temperature sensor and the engine speed sensor.
Check the connections, the continuity and the absence of interference resistance of the following components:
– the air flowmeter (apply DF056 Air flow sensor circuit)
– the engine coolant temperature sensor (apply DF001 Coolant temperature sensor circuit)
– the fuel temperature sensor (apply DF098 Fuel temperature sensor circuit)
– the engine speed sensor (apply DF195 Engine speed/camshaft sensor consistency).

– Check the consistency between the IMA* codes entered and the codes engraved on the injector bodies.
– Check that the particle filter differential pressure sensor is correctly positioned and connected (see MR 395, 402,
405, 364 or 370 Mechanical, 19B Exhaust, Particle filter pressure sensor: Removal - Refitting),
– Check the exhaust pipe (see TEST1 Exhaust pipe check),
– Check the air inlet circuit (see TEST4 Turbocharged air inlet circuit check),
– Check the air flowmeter (see TEST5 Air flowmeter),
– Check the turbocharger (see TEST7 Variable geometry turbocharger check),
– Check the injectors (see TEST10 Poor injector operation),
– Check the cylinder compressions.
