High pressure pump:
The pump draws in fuel from the tank, which passes through a fuel filter and supplies the fuel injectors.
Rail pressure sensor:
This sensor is fitted to the rail and indicates the pressure inside the rail.
Rail pressure regulator:
This component regulates the high pressure of the fuel in the injection system.
Fuel temperature sensor:
This sensor measures the fuel return temperature from the pump and injector return.
Four injectors:
These injectors enable rapid, precise metering of the quantity of fuel injected, with excellent injection process repeat
action.
Vacuum pump:
The vacuum pump is driven by the camshaft. The pump provides the vacuum required to operate the following
components: control solenoid valve, brake servo.
Control solenoid valve:
The solenoid valve controls the vacuum pump and the turbocharger vane control diaphragm.
Turbocharger:
The turbocharger is used to supply the engine with more air.
Turbocharger pressure sensor:
This sensor indicates the pressure at the turbocharger air cooler outlet before the damper valve.
Air mass flow meter:
The flowmeter measures the amount of fresh air entering the engine.
EGR valve:
Exhaust gas recirculation considerably reduces the nitrogen oxide emissions (NOx).
EGR position sensor:
The sensor gives the position of the EGR solenoid valve.
Damper valve:
The damper valve is used:
– When the engine is switched off, to dampen the engine which helps stop the engine.
– When in the rest position; the valve is open by default.

Cruise control/speed limiter management:
The vehicle cruise control function, when activated, allows you to keep the vehicle speed at a selected value
regardless of the driving conditions encountered.
Using the control buttons, the driver can increase or reduce the speed of the vehicle.
If the driver wishes to exceed the cruising speed, he may:
– press the accelerator pedal and exceed the cruising speed (the vehicle will return to the initial cruising speed once
the driver takes his foot off the pedal),
– press the system control buttons.
The cruise control function can be deselected either by:
– the system control buttons,
– deactivating the cruise control switch,
– when system events are detected, such as the brake pedal or clutch being pressed,
– when system errors are detected such as an inconsistent vehicle speed.
The cruise control function can also be temporarily disabled when the driver wants to increase speed by pressing
the accelerator pedal. The cruising speed is resumed when the driver releases the accelerator pedal.
The vehicle will then attempt to reach the cruising speed at a controlled acceleration rate.
It is possible to reactivate the vehicle speed control and resume the last cruising speed after deactivation (computer
feed not cut off).
When activated (using the selection switch) the vehicle speed limiter function limits the vehicle speed to a
preselected value. The driver controls the vehicle in the normal way using the accelerator pedal until the limit speed
is reached.
If an attempt is made to exceed this speed, the system ignores the pedal request and controls the vehicle speed in
the same way as the cruise control function, provided that the driver keeps the accelerator pedal depressed.
As with the cruise control function, the cruising speed can be altered using the control buttons by pressing briefly or
keeping the switch pressed.
For safety reasons, it is possible to exceed the limit speed by depressing the accelerator pedal and exceeding the
pedal position limit value. The vehicle speed is then totally controlled as a function of pedal position until the speed
falls back below the cruising speed when the speed limiter function will once again be reactivated.
If the driver wishes to exceed the cruising speed, he may:
– exceed the accelerator pedal's kickdown point,
– increase the limit speed by pressing or pressing and holding the limit speed switch.
The speed limiter function can be deselected either:
– the system control buttons,
– by switching off the speed limiter switch,
– when system events are detected, such as the brake pedal or clutch being pressed,
– when system errors are detected such as an inconsistent vehicle speed.

Deal with fault DF012 Sensor feed voltage no. 2 first, if it is
present or stored.
Conditions for applying the fault finding procedure to a
stored fault:
The fault occurs if the brake pedal and the accelerator pedal
are depressed simultaneously for more than 30 seconds
without any movement.
Special notes:
Do not interpret the conditions under which the fault occurs.
Make sure that the accelerator pedal is not mechanically jammed (broken spring, floor carpet, etc.).
Check that the brake switch is correctly positioned in its housing.
If the fault is still present, deal with fault DF165 2.DEF.

Check for + 12 V after ignition feed on the connections of the brake pedal switch connector and the
condition of the fuse.
– Connection code AP10 of component 160.
– Connection code SP13 of component 160.
Disconnect the ABS - ESP and check the continuity and insulation against + 12 V and against earth
of the following connection:
– Connection code 65A between components 160 and 1094.
Check that the brake pedal switch is working correctly:
in rest position: infinite resistance continuity between the following connections:
– Connection code 65A of component 160.
– Connection code AP10 of component 160.
depressed: continuity between the following connections:

STATUS DEFINITIONDEPRESSED: This status indicates that the brake pedal is in the depressed position.
RELEASED: This status indicates that the brake pedal is in the released position.
NOTESSpecial notes:
Only perform these tests if the statuses do not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C
DEPRESSEDStatus ET039 is RELEASED when there is no action on the brake pedal.
In the event of a fault, see the interpretation of statuses ET704 Brake switch no. 1
and ET705 Brake switch no. 2.
RELEASEDStatus ET039 is DEPRESSED when there is pressure on the brake pedal.
In the event of a fault, see the interpretation of statuses ET704 Brake switch no. 1
and ET705 Brake switch no. 2.
