NOTESPriority for dealing with a combination of faults:
In the event of a fault DF154, DF119 Camshaft sensor signal and DF080 Camshaft
dephaser circuit, ignore fault DF080 and deal with the other 2 faults first.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the starter motor has been running for 10 seconds
or at an engine speed above 600 rpm.
Special note:
–OBD warning light illuminated.
Check the cleanliness, condition and the assembly of the flywheel.
Repair if necessary.
If the flywheel has been replaced or removed, the flywheel target has to be reinitialised, then reprogrammed.
Programming reinitialisation:
Run command RZ005.
Carrying out the flywheel target programming:
Accelerate up to 4000 rpm in third gear then decelerate, foot off the pedal, to power take-up speed*.
Then repeat immediately.
In rare cases, fault DF125 Torquemeter programming may appear.
(*This is the moment when, during deceleration with no load, the engine drops to idle speed and recovers torque).

Apply the procedure for dealing with faults DF081 Solenoid valve canister bleed and
DF085 Fuel pump relay first if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after an attempt is made to start the engine.
Special note:

Check the cleanliness, condition and fitting of the fuel vapour absorber.
Repair if necessary.
If the fault is still present, adjust the harness so that the fault status changes (present  stored).
Look for any damage to the wiring harness, and check the condition and connection of the injection computer
and fuel vapour absorber connectors.
Repair if necessary.
If the fault is still present, check for the +12V on track 1 of the fuel vapour absorber.
If the +12V is not present, check the following connection for insulation, continuity and the absence of
interference resistance:
Fuel vapour absorber track 1 track 2 of connector PPM1 on the Protection and Switching Unit
Repair if necessary.
If the fault is still present, disconnect the battery and the injection computer.
Check the insulation, continuity and the absence of interference resistance on the following connection:
Computer, connectorC, track E1petrol vapour absorber track 2
Repair if necessary.
If the fault is still present, measure the resistance between tracks 1 and 2 of the fuel vapour absorber bleed
solenoid valve.
Replace the bleed solenoid valve for the fuel vapour absorber if the resistance is not 26 ±4 at 23 °C.
If the fault is still present, check the insulation, continuity and the absence of interference resistance on the
following connections:
Computer, connectorC, track D1 track 1 of the PEM connector of the Protection
and Switching Unit
Repair if necessary.
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.

Special note:
The acquisition is made if the vehicle is not fitted with an automatic transmission.
Check the cleanliness, condition and assembly of the clutch pedal switch and its connections.

If the fault is still present, disconnect the switch. Check that when the clutch pedal is depressed, the switch is active,
and that when the clutch pedal is released, that the switch is not active and that the recommendations regarding
clutch pedal clearance are still valid (see MR 364, Mechanics,20A, Clutch
Replace the switch if necessary.
If the fault is still present, manipulate the harness so that the status changes (present  stored).
Look for any damage to the wiring harness, and check the condition and connection of the injection computer
and clutch pedal switch connectors.

STOREDLPG CYLINDER 1 COMBUSTION MISFIRE
1 DEF: Destructive misfire
2 DEF: Pollutant misfire
3 DEF: Non-compliance with emission control standards
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"
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 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.
Misfiring on
cylinder 1 only
The fault is probably due to a component that can only affect this cylinder:
– check the cylinder 1 pencil coil,
– check the condition and conformity of the spark plugs,
– check the cylinder 1 LPG injector
If everything is in order, check the same components on cylinder 4 (to cover a possible
cylinder recognition error).
The fault is probably due to a component that affects a pair of cylinders:
– check the ignition coil circuit concerned (apply interpretation of fault
DF072 Cylinder 1 ignition coil circuit
DF073 Cylinder 2 ignition coil circuit
DF074 Cylinder 3 ignition coil circuit
DF075 Cylinder 4 ignition coil circuit
– check the condition and conformity of the spark plugs.
