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.
