NOTESPriority when dealing with a number of faults:
– LPG fuel system: see 17C, LPG injection,
– ignition:
DF072 Cylinder 1 ignition coil circuit
DF073 Cylinder 2 ignition coil circuit
DF074 Cylinder 3 ignition coil circuit
DF075 Cylinder 4 ignition coil circuit
– flywheel signal:
DF154 Flywheel signal sensor circuit
DF125 "Torque sensor programming"
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 appears under the following conditions:
– there must be no further electrical faults,
– the programming must have been done, particularly the flywheel target,
– warm engine (minimum 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 compression's,
– 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 to the conformity check.
AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.

value- 12% < PR090 < 12%
PR090, an adaptive built-in action, is
a stored parameter designed to
program variation and engine ageing
for the idle speed regulator. These
are programmed only when the
engine is idling and warm, and no
electrical consumers (electrical
windscreen, air conditioning, GMV,
power steering) have been selected.
Therefore it adjusts slowly.

throttlePR091: Theoretical

regulation
OCR0% < PR091 < 100%
When the conditions for regulation
are met, the idle regulator continually
repositions the motorised throttle to
keep the engine speed at the idling
speed setting. The motorised throttle
opening ratio required to adhere to
the engine speed setpoint is then
given by parameter PR091.
