STOREDCOMBUSTION MISFIRE IN LPG MODE
1.DEF: Destructive misfiring
2.DEF: Pollutant 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.
– cylinder combustion misfires:
DF059 Combustion misfire in cylinder 1,
DF060 Combustion misfire in cylinder 2,
DF061 Combustion misfire in cylinder 3,
DF062 Combustion misfire in cylinder 4.
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.
Check the LPG injectors.
Check the condition and conformity of the spark plugs.
Check the ignition pencil coils.
If the fault is still present, carry out the following checks:
– check the flywheel sensor,
– check the condition and cleanliness of the flywheel,
– check the flywheel sensor mounting,
– check the sensor/flywheel air gap,
– check the cylinder compressions,
– check the LPG fuel system,
– check the complete ignition system (see MR 364 or 370 Mechanics, 17A, Ignition),
– check the hydraulic tappets if there is camshaft noise (see MR 364 or 370 Mechanics, 11A, Top and front of
engine).
If the fault is still present, deal with the other faults then proceed with the conformity check.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.

Apply the procedure for dealing with faults DF012 Sensor supply voltage no. 2,
DF012 Sensor supply voltage no. 2, DF197 Pedal sensor circuit gang 1, DF198
Pedal sensor circuit gang 2 if these are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present when brake and accelerator pedals are depressed
simultaneously for 30 seconds.
Special note:
–Severity 2 fault warning light illuminated,
– defect mode types 3 and 4.
1.DEF
NOTESSpecial note:
–types 2 and 3 defect modes: vehicle and engine speed
restriction, ESP and cruise control/speed limiter are
deactivated.
Check that the accelerator pedal is not jammed and that nothing is impairing its operation (floor carpet, etc.).
Check the connection and condition of the 6-track connector for the accelerator pedal potentiometer.
Repair if necessary.
Check the connection and condition of computer connector A.
Repair if necessary.
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.
