After repair, check that the catalytic converter is 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 touch the accelerator pedal or 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 388 (Logan and
Sandero), MR 451 (Duster) or MR 423 (Thalia 2/Symbol 2), Mechanical, 19B, Exhaust, Catalytic converter:
Removal - Refitting).

For engines: K4M, K7M, D4D
NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero, Kangoo VLL.
Check the connection and condition of the connector of the additional fuel circuit solenoid valve, component code
1640 and the injection computer connector, component code 120.
If the connector or connectors are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the continuity, insulation, and absence of interference resistance on the following connections:
–3ACM between components 1640 and 120,
–3FB between components 1640 and 1047.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring. Otherwise replace the wiring.
Check the supply of the solenoid valve using a test light, by running command AC217 Additional fuel circuit
solenoid valve.
Check the internal resistance of the solenoid valve, component code 1640 on the computer connector; its value
must be between: 12 < X 16 (Duster F4R engine) or 22 < X 30 (Duster K4M engine). If the resistance
is incorrect, replace the solenoid valve.
If the fault is still present, contact the Techline.

NOTESThis fault corresponds to an electrical fault of the additional fuel circuit injector, which is
fitted directly on the throttle valve. It is not a solenoid valve fault.
See the Wiring Diagrams Technical Note for Duster.
Check the fitting and sealing of the additional fuel circuit injector
If there is leakage, replace the defective component (the injector inlet hose, the injector seal, the additional fuel
circuit injector).
Check the connection and condition of the connector of the additional fuel circuit injector, component code 1640
and the injection computer connector, component code 120.
If the connector or connectors are faulty and there is a repair procedure (see Technical Note 6015A, Electrical

Check the supply of the additional fuel circuit injector using a multimeter in the voltmeter position (direct current
mode).
Run command AC217 Additional fuel circuit solenoid valve and check that the average voltage reading is
different from 0 V.
Check the internal resistance of the additional fuel circuit injector, component code 1640 on the computer
connector. Its value must be between: 13.775 X 15.225 or 24 X 30 (F4R engine on Duster) at

Conditions for application to a stored fault:
The fault is declared present:
–For 1.DEF engine at idle speed.
–For 2.DEF, if impossible to see the fault present, deal with it as stored.
See the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/

With the brake pedal released, check ET039 Brake pedal and ET799 Brake wire contact.
If ET039 is Released and ET799 is Inactive.
Check the fitting and mechanical operation of the brake pedal (the pedal returns properly).
If the check is incorrect, check the braking system.
Remove the brake pedal switch, component code 160 (see MR 388 (Logan and Sandero), MR 451 (Duster),
MR 423 (Thalia 2/Symbol 2), Mechanical, 37A, Mechanical component controls, Brake pedal switch:
Removal - Refitting or MR 430 (Clio II F 6), MR 374 (Kangoo VLL), Mechanical, 37A, Mechanical component
controls, Brake pedal: Removal - Refitting) and, without depressing the pedal, press sufficiently on the brake
pedal switch to seat it completely in its position.
Lock it by turning it an eighth of a turn.
The fault should change from present to stored.
