NOTESConditions for applying the fault finding procedure to stored faults:
The fault is declared present after the ignition is switched on or after the engine has
been running at an engine speed above 600 rpm.
Special notes:
–OBD warning light illuminated.
–Throttle valve defect mode type 6.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III, or
MODUS.
Check the cleanliness, condition, and fitting of the turbocharging solenoid valve (component code 436).
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.
If the fault is still present, manipulate the wiring harness in order to note a change in fault status (present
→
stored).
Check the condition of the engine management computer connector (component code 120).
Look for possible damage to the wiring harness.
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 for +12 V on connection 3AHN of the turbocharger solenoid valve, component code 436.
If +12 V is not present, check the insulation, continuity, and the absence of interference resistance on
connection:
●3AHN between components 120 and 436.
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.

NOTESPriorities when dealing with a number of faults:
Deal with the faults DF084 Actuator relay control circuit and DF046 Battery voltage
if they are present or stored.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running or when running the command
AC017 Bleed canister solenoid.
Special notes:
CO/CC.1: The valve remains stuck shut and there is a smell of fuel. The OBD warning
light is illuminated.
CC.0: The valve remains stuck open: hesitation when driving, risk of engine stalling and
difficult to restart the engine.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III,
or MODUS.
Check the condition of the fuel vapour absorber bleed solenoid valve connector (component code 371).
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
