STOREDMOVEMENT DURING REGENERATION PRESSURE SENSOR
NOTESConditions for applying fault finding procedures to stored faults:
The fault becomes present during an After-Sales regeneration carried out using the
diagnostic tool at a speed above zero.
Special notes:
If the fault is present:
– regeneration in progress is stopped.
IMPORTANT
The fault is present because the vehicle was driven while the After-Sales regeneration was in progress.
The vehicle must remain stationary throughout regeneration.
DO NOT DRIVE THE VEHICLE DURING AFTER-SALES REGENERATION.
CHECK THAT THE VEHICLE IS CORRECTLY IMMOBILISED.
– switch off the ignition and wait for the diagnostic tool message (maximum time 8 minutes): Communication
lost with computer: EDC16C36, check the tool connection and computer supply.
– switch on the ignition,
– establish dialogue with the injection computer,
– clear the faults from the computer memory.
Check that there are no leaks or blockages in the exhaust pipe,
– Repair if necessary
– carry out another After-Sales regeneration,
– run command SC017 Particle filter regeneration and follow the procedure (see Interpretation of commands).
If the fault is still present, contact the Techline.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– particle filter regeneration is inhibited,
– blue/white smoke and black particles coming from the exhaust,
the OBD warning light will illuminate after three consecutive driving cycles (start + 5
seconds, switch off the ignition and wait 40 seconds).
Priorities when dealing with a number of faults:
– DF315 Particle filter diff.* pressure sensor if present or stored
IMPORTANT
In the long term, this fault may lead to premature wear and a greater risk of
turbocharger failure.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.

Check the status of the differential pressure sensor connector and engine management computer.
If the connector or 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.
Check the particle filter is present.
If it is present,
Visually check that the particle filter is in good condition by positioning the vehicle on a lift:
– not damaged (no abnormal welds, if necessary compare it with another vehicle fitted with particle filter),
– if there are After-Sales sleeves, as a result of a previous operation, check that the particle filter's contents were
not emptied out when it was removed.
If the particle filter is not in good condition or is absent:
– Replace the particle filter.
– Switch on the ignition.
– establish dialogue with the injection computer,
– run command SC036 Reinitialise programming,
–select After particle filter replacement as the operation type, then follow the instructions given by the
diagnostic tool,
– switch off the ignition,
– wait for the diagnostic tool message (maximum time 8 minutes): Communication lost with computer:
EDC16C36, check the tool connection and computer supply before switching the ignition back on.
– clear the faults from the computer memory (this operation must be carried out within 3 minutes of the ignition
being switched on).
– Check the weight of soot: PR383 Weight of soot in the particle filter.
– If PR383
≥ 1 g. Apply the procedure of test 12 Manual clearing of the weight of soot.
If the fault is still present, contact the Techline.
