STOREDFUEL CIRCUIT OPERATING FAULT
1.DEF: Non-compliance with emission control standards
2.DEF: Component in bad condition
NOTESPriority when dealing with a number of faults:
If faults DF085 Fuel pump relay control circuit, DF549 Canister bleed circuit and
injector faults
DF026 Cylinder 1 injector control circuit,
DF027 Cylinder 2 injector control circuit;
DF028 Cylinder 3 injector control circuit,
DF029 Injector control circuit cylinder 4, are present or stored, deal with these first.
Special note:
–the OBD warning light is lit,
– a fuel supply system fault can lead to starting difficulties, and loss of comfort and
power.
Check the cleanliness, condition and fitting of the fuel vapour absorber.
Check the connections and correct operation of the petrol pump.
Check the cleanliness, condition and fitting of the injectors and their sealing.
Repair if necessary.
Check:
– that the fuel is present and correct,
– the tank vent,
– that there are no leaks on the petrol circuit (from the tank to the injectors),
– that there are no kinked hoses (especially after dismantling),
– the fuel flow rate and pressure.
Repair the faulty component(s) if necessary (see MR 364 or 370 Mechanics, 13A, Fuel supply).
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.
