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
DEFINITIONNOT DETECTED: This status indicates that the cruise control or speed limiter function
is not present on the vehicle.
INACTIVE: This status indicates that the main on/off switch of the cruise control/speed
limiter is in the rest (or neutral) position.
LIMITER: This status indicates that the driver has used the main switch to select the
speed limiter.
CRUISE CONTROL: This status indicates that the driver has used the main switch to
select the cruise control.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant
temperature > 80°C
