STOREDCOMBUSTION MISFIRING ON CYLINDER 4
1.DEF : destructive misfiring
2.DEF : pollutant misfiring
NOTESPriority for dealing with a combination of faults:
– ignition: DF072, DF073, DF074 and DF075.
– fuel supply system: DF026, DF027, DF028, DF029 and DF085.
– engine flywheel signal: DF005 and DF125.
Check whether other cylinders have misfiring faults before starting the following fault
finding procedure.
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,
– programming must be carried out.
– engine warm (min 75°C),
– idling with all the electrical consumers activated for 15 minutes.
Special note:
–OBD warning light illuminated.
Misfiring on
cylinder 4 only
Combustion
misfires in
cylinders 1 and 4
(see DF059
Combustion
misfires in
cylinder 1 and
DF062
Combustion
misfires in
cylinder 4)
The fault is probably due to a component that can only affect this cylinder:
– check the cylinder 4 injector
– check the condition and conformity of the spark plugs,
– check the cylinder 4 pencil coil.
If everything is okay, check the same components on cylinder 1 (to correct
a possible cylinder identification error).
Carry out the steps "according to the repair".
The fault is probably due to a component that affects a pair of cylinders:
– check the relevant ignition coil circuit (apply the fault finding procedure DF072
Ignition coil circuit 1 or DF075 Ignition coil circuit 4),
– check the condition and conformity of the spark plugs.
– Carry out the steps "according to the repair".
AFTER REPAIREnsure that all the faults have been dealt with.
Clear the stored faults. Do not clear the programming.
To check that the system has been properly repaired:
– there must be no further electrical faults,
– programming has been carried out,
– warm engine (minimum 75°C).
– running at idle speed with all electrical consumers drawing power for 15 minutes.
– if the fault is still absent, check that the catalytic converter is in good condition. Use
command SC006 Run OBD Test: Catalytic converter.

MOTORISED THROTTLE VALVE SERVO
1.DEF : motorised throttle stop search fault
2.DEF : motorised throttle rest position programming error
3.DEF : motorised throttle servo fault
4.DEF : the position memory function does not work
5.DEF : when the throttle bounces off the lower stop, a relatively large permanent
discrepancy can be seen between the set position and actual position of the throttle.
The bounce detection is based on this error. The oscillation fault, after N oscillations
detected, activates the Limp Home defect mode.
6.DEF : when there is a micro-break on gang 1 of the sensor, the voltage delivered
is minimal (0V), which broadly corresponds to complete throttle closure. We can then
see the gang 1 signal lapse in relation to the gang 2 signal, which remains correct.
This lapse speed of one gang in relation to another is used to detect micro-breaks.
The micro-break fault does not activate any defect mode or illuminate any warning
lights.
7.DEF : non-compliance with emission control standards
NOTESPriority for dealing with a combination of faults:
Apply the procedure for dealing with faults DF011 Sensor supply voltage no. 1,
DF078 Throttle potentiometer control circuit, DF095 Throttle potentiometer
circuit gang 1 and DF096 Throttle potentiometer circuit gang 2 first if they are
present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after:
– A change in engine speed.
– the air temperature must be between 5°C and 105°C inclusive.
Special note:
If 1 DEF, 2.DEF or 3.DEF:
– the OBD warning light is lit,
– throttle valve defect mode types 1, 2 and 6.
If 4.DEF or 5.DEF:
– the OBD warning light is lit,
– Throttle valve defect mode types 1, 2, 4 and 6.
Check the cleanliness, condition and fitting of the throttle valve.
Repair if necessary.
If the fault is still present, manually check that the throttle valve rotates correctly.
Repair if necessary.
If the fault is still present, manipulate the harness in order to note a change in fault status (present  stored).
Look for possible damage to the wiring harness, check the condition and the connection of the connectors of the
injection computer and motorised throttle valve.
Repair if necessary.
