After repair, check that the catalytic converter was not damaged by the misfire.
To do this, switch on the ignition, run the catalytic converter test SC006 Run OBD test: Catalytic converter and
start the engine (only depress the brake pedal to authorise the starting of the engine,
Do not depress the accelerator pedal or the clutch pedal).
At the end, check the test results:
STATUS1: Fault finding was not performed/impossible to obtain the necessary conditions
STATUS2: The component is in an average condition - sensor OK
STATUS3: The component is in a good condition - sensor OK
STATUS4: The component is in poor condition - replace the catalytic converter (see MR 451 (Duster), MR 423
(Thalia 2/Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL), Mechanical, 19B, Exhaust, Catalytic
converter: Removal - Refitting).
Note: The catalytic converter procedure is not carried out if a fault is present.
Important: Do not run the procedure if a new catalytic converter is fitted.
2.DEF
NOTESNone.
Check the ignition coil circuit of cylinder 3,
Check the fuel supply circuit (see MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), MR 430 (Clio II F 6) or MR 374
(Kangoo VLL), Mechanical, 13A, Fuel supply, Fuel circuit: Operating diagram),
Check the fuel supply pump circuit,
Check the condition of the cylinder 3 injector (see MR 451 (Duster), MR 423 (Thalia 2/Symbol 2), MR 430 (Clio
II F 6) or MR 374 (Kangoo VLL), Mechanical, 17B, Petrol injection, Injector rail - Injectors: Removal -
Refitting),
Check the compression of cylinder 3.
