STOREDLPG CYLINDER 2 COMBUSTION MISFIRE
1.DEF: Destructive misfiring
2.DEF: Polluting misfiring
3.DEF: Non-compliance with emission control standards
NOTESPriority when dealing with a number of faults:
– LPG fuel system: see 17C, LPG injection,
– ignition:
DF361 Ignition coil circuit cylinders 1-4,
DF362 Ignition coil circuit cylinders 2-3.
– flywheel signal:
DF154 Flywheel signal sensor circuit,
DF457 Engine flywheel target.
Check whether there are other cylinders with an LPG combustion misfire fault detected
by the tool before starting the following fault finding procedure.
Conditions for applying the fault finding procedure to stored faults:
The fault is considered present under the following conditions:
– there must be no further electrical faults,
– the programming must have been done, particularly the flywheel target,
– engine warm (min 75°C),
– run the engine at idle speed with all electrical consumers switched on for
approximately 15 minutes.
Special note:
– catalytic converter misfire: OBD warning light flashes when the fault is present then
is continuously lit,
– pollutant combustion misfire: OBD warning light lit continuously.
–engine unstable, loss of power and vibrations.
Combustion
misfires in
cylinder 2 only
Combustion
misfires in
cylinders 2 and 3
The fault is probably due to a component that can only affect this cylinder:
– check the cylinder 2 pencil coil,
– check the condition and conformity of the spark plugs,
– check the cylinder 2 LPG injector.
If everything is in order, check the same components on cylinder 3 (to correct a possible
cylinder identification error).
The fault is probably due to a component that affects a pair of cylinders:
– check the ignition coil circuit concerned (apply the interpretation of fault DF361
Ignition coil control 1-4 or DF362 Ignition coil control 2-3),
– check the condition and conformity of the spark plugs.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present with the engine running and with a heating and air
conditioning system request.
Priorities when dealing with a combination of faults:
Deal with fault DF232 Refrigerant pressure sensor circuit first if it is present or
stored
When the fault is present or stored, the heating and air conditioning system is inhibited.
Check fuse F22 (10A) of the UPC and the condition of the air conditioning compressor connector.
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the air conditioning compressor wiring.
If the wiring is faulty and there is a repair procedure (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Manually check whether the compressor is jammed (turn the clutch plate manually to check that there is no point
of resistance). In the event of sticking, replace the air conditioning compressor (see MR 364 (Mégane II) or 370
(Scénic II), Mechanical, Heating and air conditioning system, 62A, Air conditioning, Compressor:
Removal - Refitting).
Top up with freon, check for any leaks and repair if necessary (see MR 364 (Mégane II) or 370 (Scénic II),
Mechanical, Heating and air conditioning system, 62A, Air conditioning, Refrigerant circuit: checks,
Refrigerant circuit: Draining - Filling).
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.
