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.
– warm engine (minimum 75°C),
– idling with all the electrical consumers activated for 15 minutes.
Special note:
–OBD warning light illuminated.
Misfiring on
cylinder 1 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 1 injector
– check the condition and conformity of the spark plugs,
– check the cylinder 1 pencil coil.
If everything is in order, check the same components on cylinder 4 (to cover
a possible cylinder recognition 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 DF720
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.
