Check the cleanliness of the throttle valve, component code 1076 and that the throttle rotates properly (no
resistance point)
Check the cleanliness and condition of the throttle valve connector.
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the cleanliness and condition of the injection computer connector, component code 120.
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector(s), otherwise replace the wiring.
Check the insulation, continuity and the absence of interference resistance on the following connections:
–3MO between components 120 and 1076,
–3MP between components 120 and 1076,
–3MN between components 120 and 1076.
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 it.
If the throttle valve has been replaced, reinitialise the programming by running command RZ031 Throttle stop

374 (Kangoo VLL), Mechanical, 17B, Petrol injection, Injector rail - Injectors: Removal - Refitting),
Check the cylinder compressions.
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 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), MR 423 (Thalia 2/Symbol 2), MR 430 (Clio II F 6) or MR 374 (Kangoo VLL),

AFTER REPAIRCheck that all faults have been dealt with.
Do not clear the programming.
To check that the system has been repaired correctly:
– 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 reappears, continue the fault finding procedure.

The fault is present after starting the engine and under the following conditions:
– engine running at idling speed
Special note:

Check the connection and condition of the connector of the crankshaft position sensor, component code 149
and of 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.
Measure the resistance of the crankshaft position sensor component code 149 between connections 3BL and
3BG on the injection computer connector, component code 120.
If the resistance of the crankshaft position sensor is not between 175 X 295 or 200 X 270 (F4R
engine of Duster) (between 0°C and 40°C), replace the crankshaft position sensor, component code 149 (see

Check the insulation and continuity of the following connections:
–3BG between components 149 and 120,
–3BL between components 149 and 120.
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 it.
Check that the 58 teeth of the flywheel target are not damaged or broken.
Check that the target is securely mounted on the flywheel (see MR 388 (Logan and Sandero), MR 451 (Duster),
