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 4 only
The fault is probably due to a component that can only affect this cylinder:
– check the pencil coil of cylinder 4,
– check the condition and conformity of the spark plugs,
– check the cylinder 4 LPG injector
If everything is in order, check the same components on cylinder 1 (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.

AFTER REPAIRFollow the instructions to confirm repair.
Deal with any other faults.
Clear the stored faults.

– 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.

FLYWHEEL SIGNAL
NOTESThere must be no present or stored faults.
Information:
If the flywheel has been replaced or removed, reinitialise the flywheel target
programming.
Check the mounting and positioning of the TDC sensor (see MR 364 Mechanics, 10A, Engine and
peripherals).
Repair if necessary.
Check the cleanliness and condition of the TDC sensor and its connections.
Check the condition of the wire.
Repair if necessary.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Using the universal bornier, check the insulation and continuity on the following connections:
Injection computer, connectorB, track E4 Track 2 of the TDC sensor
Injection computer, connectorB, track F3 track 1 of the TDC sensor
Repair if necessary.
Measure the resistance of the TDC sensor between tracks 1 and 2.
Replace the sensor if the resistance is not 200 to 270 at 23 °C.
If the sensor has been replaced, reset the flywheel signal programming.
Flywheel signal programming reinitialisation procedure:
Accelerate up to 4000 rpm in third gear ratio, then decelerate to power take-up speed*.
Then repeat immediately.
(* This is the moment when, during deceleration with no load, the engine drops to idle speed and recovers torque.)
If the fault is still present, check the cleanliness and condition of the flywheel.
AFTER REPAIRIf the TDC sensor has been replaced, reinitialise the programming (RZ005).
Repeat the conformity check from the start.
