NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present with the ignition on or the engine running, or during
command AC015 Fuel pump relay.
Special notes:
CO/CC.1: The effect of the fault is the same as running out of fuel. The vehicle stalls
and cannot be restarted.
CC.0: There is danger of fire in the event of petrol leaking during an accident.
Intermittent CO: Risk of intermittent ignition cut-off and draining the battery.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check the condition of the engine management computer connector (component code 120).
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.
For NEW TWINGO or E33:
Check the condition of the fuel pump relay (component code 236).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Use the "universal bornier" to check the insulation and continuity of the following connection:
●3AC between components 236 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 for an earth during activation of command AC015 Fuel pump relay.

With the ignition on, if the + 12 V is still not present on the fuel pump relay connector, there is a fault in the engine
fuse and relay box.
Run fault finding on the engine fuse and relay box to check the continuity of the following connection:
●BP17 between components 120 and 597,
●BP17 between components 1033 and 597.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, check the battery and run fault finding on the charging circuit (see Technical Note 6014A,
Checking the charging circuit).
For CLIO III or MODUS:
Check the condition of the Protection and Switching Unit (see Wiring Diagram Technical Note, CLIO III or
MODUS, component code 1337).
If the connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Use the "universal bornier" to check the insulation and continuity of the following connection:
●3AC between components 1337 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 for an earth during activation of command AC015 Fuel pump relay.
If the fault is still present, there is a fault in the Protection and Switching Unit (the fuel pump relay is in the Protection
and Switching Unit and cannot be dismantled).
Run fault finding on the UPC, component code 1337 (see 87G, Engine compartment connection unit).
If the fault is still present, contact the Techline.
AFTER REPAIRFollow the instructions to confirm repair:
- If the fault is present, continue to deal with the fault.
- If the fault is stored, ignore it.

–DF062 Misfiring on cylinder 4,
–DF436 Combustion misfiring detection,
if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is considered present when the engine is running.
Special notes:
1.DEF: As soon as the fault is detected, the injection is cut for the faulty cylinder(s) to
limit the rise in temperature inside the catalytic converter. The OBD warning light
flashes for as long as the fault is present.
2.DEF: The OBD warning light is continuously lit.
Check:
–the level of fuel in the tank,
–the conformity and the grade of the fuel, apply test 1 Petrol conformity check,
–the fuel filter,
–the fuel pump,
–the fuel lines,
–the fuel pressure.
If there is no present or stored misfiring fault, the misfiring was caused by the low fuel level.

STOREDFUEL CIRCUIT OPERATING FAULT1.DEF: Operational fault finding on the fuel circuit should detect a fault on the petrol
system causing the EOBD pollutant emission thresholds to be exceeded.
The on-board diagnostic can detect:
–clogging of the injectors or an injector flow fault,
–a fault in the supply system (pressure regulator, fuel pump, filter, etc.),
–a poor connection in the petrol or injection circuits.
2.DEF: EOBD
NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running (wait for approximately
2 minutes).
Check:
–the fuel pressure,
–the fuel filter,
–the fuel pipes,
–clogging of the injectors or an injector flow fault (see MR 392 (Clio III), MR 385 (Modus), MR 411
(New Twingo), or MR 442 (E33), Mechanical, 13A, Fuel supply).

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,
the engine must be warm (minimum 75˚C), and idling, with all electrical consumers
running for 15 minutes.
