Injection computer:
The injection computer manages the entire system.
Its role is to define the engine optimum operating mode and to inform the driver (via the instrument panel, information
display, and buzzer) and to communicate with the other computers.
Fuel vapour recirculation solenoid valve:
The fuel vapour absorber works like a ''sponge'' for petrol vapours and enables gases coming from the tank to be
collected.
Upstream oxygen sensor:
This sensor measures the amount of oxygen in the exhaust gas.
The voltage supplied to the computer by the sensor indicates the amount of oxygen in the exhaust gas - a rich
mixture or a lean mixture - and a program is adopted accordingly.
Downstream oxygen sensor:
This sensor measures the amount of oxygen in the exhaust gas.
The voltage supplied to the computer by the sensor indicates the amount of oxygen in the exhaust gas - a rich
mixture or a lean mixture - and a program is adopted accordingly.
Pinking sensor:
The sensor detects engine knocking and sends its electrical signal to the injection computer.
Oil pressure sensor:
This sensor measures the engine oil pressure.
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.
Ignition coil:
This acts both as an energy storage battery and a transformer. It generates high voltage ignition pulses and the
energy required to ignite the mixture.
Motorised throttle valve:
The motorised throttle valve supplies the engine with varying mixtures of fuel and air according to the load required.
This electronic control detects the position of the accelerator using a sensor (potentiometer) to inject the mixture.

Defect modes
Motorised throttle valve
In defect mode, the motorised throttle valve can assume six different statuses.
ET564 Defect mode type 1
This type groups together the faults that prevent the throttle from being controlled.
It causes the throttle control to be stopped: the throttle is in its safe position. By depressing the pedal, it is possible
to modulate the torque by cylinder cut-off and advance in order to keep the vehicle running.
The ESP, cruise control/speed limiter and automatic/sequential gearbox systems change to "defect mode". This
defect mode is always accompanied by the Type 2 defect mode.
ET565 Defect mode type 2
This type groups together the faults preventing the system from controlling the air flow modulation.
The associated defect mode limits engine speed by cutting off the injection (limiting engine speed to 2400 rpm at idle
speed and to 3500 rpm in other gears).
ET566 Defect mode type 3
This type groups together faults allowing you to deduce that the system has lost the accelerator pedal signal, but still
controls the air flow modulation (motorised throttle servo operational). Defect mode is associated with a constant
pedal setpoint for each gear ratio. The vehicle speed can vary by changing gear.
Suggested speeds on a flat road:
–12 mph (20 km/h) max in 1 - st,
–21 mph (35 km/h) max in 2 - nd,
–27 mph (45 km/h) max in 3 - rd,
–39 mph (65 km/h) max in 4 - th,
–below 54 mph (90 km/h) in 5 - th and 6 - th.
ET567 Defect mode type 4
This type covers faults that affect the motorised throttle valve monitoring system, the pedal and the turbocharging
circuit (for D4FT 780) or for faults for which there is a viable safety operating mode for the system.
The associated defect mode is a limitation of the throttle opening according to the engine speed. This results in the
speed being limited to below 66 mph (110 km/h) in 5 - th and 6 - th gear and giving the impression of a "soft"
accelerator pedal.Note:
This defect mode is an effect which occurs due to a fault, but does not necessarily originate from the throttle valve
itself.

PROCEDURE:
Before any computer programming, only Vdiag 54 and 50 (see previous page):
–Run the command SC003 'Save computer data.
Any time the computer has been programmed
–Switch the ignition off and then on again.
–Select the UCH domain using the diagnostic tool.
–In repair mode, run the command SC017 "Programming the injection immobiliser code" and follow the
instructions given by the diagnostic tool.
–Switch the ignition off and then on again.
–Select the INJECTION subgroup and check status ET341 Immobiliser code programmed.
–Run the command SC001 ''Write saved data" Vdiag 54 only.
IF ET341 = YES
–Start and then stop the engine (to initialise the computer) and wait 30 seconds.
–Switch the ignition back on and use the diagnostic tool to carry out the following steps:
–Run the command VP010 Write VIN.
–After injection system programming, stored faults may appear on other computers. Clear the memory of
these computers.
IF ET341: NO
–Re-run command SC017 and follow the instructions given by the diagnostic tool.
2. COMPUTER REPROGRAMMING OPERATIONS
When replacing or removing the TDC sensor, program the engine flywheel ring (see Configurations and
programming).
3. REPLACING THE MOTORISED THROTTLE VALVE
When replacing the throttle valve, program the throttle stops (see Configurations and programming).
4. REPLACING THE MOTORISED THROTTLE VALVE
When replacing the throttle valve, program the throttle stops (see Configurations and programming). IMPORTANT:
AFTER A PROGRAMMING OPERATION, DO NOT DISCONNECT THE BATTERY FOR AT LEAST
30 MINUTES (to carry out other work on the vehicle).
IMPORTANT:
Never drive the vehicle without having programmed the throttle stops.

2. PROGRAMMING
Flywheel target programming
(To be carried out when replacing or removing the TDC sensor).
The coolant temperature must be over 35˚C.
–Carry out an initial deceleration with injection cut-off (feet off the brake, accelerator and clutch pedals) between
3500 and 3000 rpm, in 3rd gear for at least 5 seconds for manual gearboxes.
–Decelerate a second time with injection cut-off (feet off the brake, accelerator and clutch pedals) between 2400 and
2000 rpm, in 3rd gear for at least 5 seconds for manual gearboxes.
Check the programming with ET089 Programming flywheel target: Performed.
Programming the throttle end stops
After replacement of the computer or the motorised throttle valve, with the ignition on, wait 30 seconds so that the
computer can program the Upper and Lower limits and then switch off the ignition and wait 30 seconds for the end of
the "Power Latch", so that the computer can store the programmed limits. Check the programming with ET051
Programming throttle stops: Performed.
Programming the alcohol level (only for vehicles running on Ethanol or E85 fuel)
Fuel recognition is carried out by observing the drift of the richness controller.
This can only be performed if the mixture regulation is looped (ET300 Mixture regulation).
Programming procedure:
–start the engine,
–wait for the engine coolant temperature to reach 75˚C and then check using the parameter PR064 "Coolant
temperature",
–run the engine at 1500 rpm for a period of at least 5 minutes,
–check that the programming has been carried out using status ET671 Alcohol level programming and
parameter PR743 Estimated alcohol level in tank,
–the programming is saved when the ignition is switched off. Note:
After replacement of the throttle valve run the command RZ005 Programming to erase any recorded
programming.
Note:
When the injection computer has not recognised the fuel composition, operation is faulty.
