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.

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, measure the resistance of the turbocharging solenoid valve between connections 3AHN
and 3AT.
If the resistance of the turbocharger solenoid valve is not between:
●21.8 Ω < X < 24.2 Ω at 23˚C, replace the solenoid valve.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by a check with

NOTESConditions for applying the fault finding procedure to stored faults
The fault is declared present with the engine running.
Special note:
Defect mode 4: speed limited to less than 66 mph (110 km/h) in 5th and 6
th and the
accelerator pedal feels spongy.
Defect mode 5: the ESP and Cruise control - Speed limiter are deactivated.
Defect mode 6: the wastegate is not controlled and opens freely.
The engine runs without turbocharging, like a naturally aspirated engine.
Use the Wiring Diagrams Technical Note for NEW TWINGO, E33, CLIO III, or
MODUS.
Check the connection of the turbocharging ducts.
Check the condition of the connector of the turbocharger pressure sensor (component code 1071), of the
wastegate solenoid valve (component code 436), and of the engine management computer (component
code 120).
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 connections:
●3AHN between components 436 and 120,
●3AT between components 436 and 120,
●3LN between components 1071 and 120,
●3LP between components 1071 and 120,
●3LQ between components 1071 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.
If the fault is still present, contact the Techline.
SIM32_V54_DF569
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.
Deal with any other faults.
Clear the stored faults.

ET567DEFECT MODE TYPE 4
STATUS
DEFINITIONACTIVE: This status indicates that defect mode type 4 is active.
INACTIVE: This status indicates that defect mode type 4 is inactive.
NOTESThere must be no present or stored faults.
This type groups together faults affecting the motorised throttle valve monitoring system, the pedal and the
turbocharging circuit for which there is a backup operating mode that is viable for the system.
The associated defect mode is a limitation of the throttle opening according to the engine speed. This is expressed
by limiting the speed to less than 66 mph (110 km/h) in 5
th and 6th and the accelerator pedal feels "soft".

ET568TYPE 5 DEFECT MODE
STATUS
DEFINITIONACTIVE: This status indicates that defect mode type 5 is active.
INACTIVE: This status indicates that defect mode type 5 is inactive.
NOTESThere must be no present or stored faults.
This type groups together faults affecting the pressure, the throttle valve control by the torque structure and the
turbocharging pressure.
Its effect is to go into pedal feedback mode instead of the permanent torque structure. The ESP and cruise control/
speed limiter systems are deactivated. The automatic or sequential gearbox goes into safe mode. The engine
management no longer accepts requests from the gearbox, and sends torque values by default to the multiplex
network.

6
STATUS
DEFINITIONACTIVE: This status indicates that defect mode type 6 is active.
INACTIVE: This status indicates that defect mode type 6 is inactive.
NOTESThere must be no present or stored faults.
This type groups the faults affecting the wastegate control in turbocharged vehicles.
Defect mode enables the engine to operate as a naturally aspirated engine.
The wastegate is no longer controlled and opens freely. The vehicle operates without turbocharging: loss of
turbocharger effectiveness (brisk engine performance, acceleration, recovery, etc.); operation as a naturally
aspirated engine.
Entry into type 1 to 5 defect mode always leads to the application of type 6 in turbocharged versions.

The atmospheric pressure value is:
PR035 ≈ 1 bar +/- 0.20 bar
In the event of a fault, consult the interpretation of DF004 Turbocharging pressure sensor circuit.
Check the cleanliness and condition of the atmospheric pressure sensor and its connections (component
code 147) and the engine management computer (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, otherwise replace the wiring.
On the atmospheric pressure sensor, component code 147, check the resistance between connections 3LG

–Check the cleanliness of the air filter.
–Replace the filter if necessary.
–Check that the air inlet circuit is not blocked.
The turbocharging system must be perfectly sealed, from the exhaust manifold to the turbocharger, from the
turbocharger to the heat exchanger and from the heat exchanger to the throttle valve.
Check that there are no air leaks:
–around the turbocharger pressure sensor,
–around the air temperature sensor.
Check absence of leaks in the wastegate capsule pressure circuit connected to the turbocharger system.
Check that the air-air heat exchanger is not clogged (presence of oil).
If there is oil in the heat exchanger, the turbocharger is certainly damaged.
Using a pressure/vacuum pump, check that the turbocharger protection and turbocharging valve capsule
diaphragms do not leak.
Check the condition the motorised throttle valve in terms of clogging.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.
