Switch off the ignition until the end of the power-latch phase, and carry out a road test
followed by a check with the diagnostic tool.

OR
STOREDAIR TAKEN INTO THE TURBOCHARGING CIRCUIT
1.DEF: Air leak in the turbocharging circuit
NOTESPriorities when dealing with a number of faults:
– DF004 Turbocharging pressure sensor circuit.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present with the engine running above 3000 rpm and during the
turbocharger regulation phase (for at least 10 seconds).
Special notes:
If the fault is present:
–the level 1 and OBD warning lights are lit,
– the vehicle performance is reduced,
– engine torque is limited,
– the turbo function is inhibited,
– particle filter regeneration is inhibited,
– the EGR function is inhibited by the engine management computer,
Check the condition of the turbocharging pressure sensor connector (component code 1071).
Check the condition of the turbocharging solenoid valve connector (component code 1475).
Check the condition of the engine management computer connector (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.
Check the continuity and insulation of the following connections:
•3LQ between components 120 and 1071,
•3LP between components 120 and 1071,
•3LN between components 120 and 1071,
•3MG between the components 120 and 1475.
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.

STATUS
DEFINITIONACTIVE: This status indicates that the thermoplunger is supplied.
INACTIVE: This status indicates that the thermoplunger is not supplied.
NOTESNone.
"INACTIVE"Statuses ET205, ET206, ET207 are INACTIVE when the ignition is switched on
and the engine stopped, or when the engine is warm.
"ACTIVE"Statuses ET205, ET206 and ET207 are ACTIVE when the engine is started, the
engine coolant temperature is low (<15°C) and the air temperature is low (<5°).
This program allows the engine coolant to be heated to enable the passenger
compartment to be heated.
The thermoplungers also act both to load the engine to improve regeneration of
the particle filter.
To control the operation of the thermoplunger relays, run the following commands:
– AC063 Thermoplunger no.1 relay,
– AC064 Thermoplunger no. 2 relay,
– AC031 Thermoplunger no.3 relay.
In the event of a fault, refer to the interpretation of faults:
– DF034 "Thermoplunger 3 relay control circuit",
– DF033 "Heating element 2 relay control circuit",
– DF032 Thermoplunger 1 relay control circuit.

DEFINITION
Statuses ET742 to ET751 correspond to the causes for the regeneration request. They
are associated with the parameters PR816 Stored regeneration start No. 1 to PR825
Stored regeneration start No. 10 which contain the record of the vehicle mileage at
the start of regeneration (e.g. PR745 Stored regeneration start No. 4 is associated
with ET745).
