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.

are depressed simultaneously for more than 1 second.
Special notes:
If the fault is present,
–the level 2 warning light illuminates if 1.DEF or 2.DEF is
present,
– turbocharging and cruise control are not authorised,

3.DEFNOTESPriorities when dealing with a number of faults:
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.

Fault finding – Interpretation of commands13B
VP036INHIBIT FUEL SUPPLY
NOTESThis command enables you to disable the supply to the injectors.
This command is carried out with the engine switched off, and ignition on.
This command allows the injectors to be locked, so that starting is not possible.
Command VP036 allows the engine compressions to be checked in complete safety without disconnecting the
injector connectors or the TDC sensor.
Procedure to follow: (cylinder no. 1 is located on the flywheel end).
– Remove all the heater plugs, connect the compression gauge.
– Position the gear lever in neutral (manual gearbox) or on position P (automatic gearbox).
– Depress the brake pedal and maintain this position.
– Activate command VP036.
– Try to start the vehicle.
– Check the engine compressions.
Start the procedure again on another cylinder.
WARNING
Keep the brake pedal depressed for the length of the test.
Re-establish control of the injectors using command VP037 Stop fuel supply inhibition.

is the engine running on all cylinders?
Check the operation of the injectors, run test 10 Poor injector operation.
If the fault is still present
Check the conformity of the accelerator pedal position sensor, the brake pedal sensor, the atmospheric pressure
sensor, the exhaust gas recirculation valve, and the damper valve (see Interpretation of statuses and
Interpretation of parameters).
Check the consistency of the signal for the air flowmeter, the engine coolant temperature sensor, the fuel
temperature sensor and the engine speed.
Check the connectors, the continuity, and the absence of interference resistance of the air flowmeter (apply DF056
Air flow sensor circuit), the engine coolant temperature sensor (apply DF001 Coolant temperature circuit), the
fuel temperature sensor (apply DF098 Fuel temperature sensor circuit), and the engine speed (apply DF195
Camshaft sensor - engine speed consistency).
Check:
– That the diesel filter is not clogged.
– That there are no leaks on the high and low pressure diesel circuits: run test 3 Low pressure circuit check.
– The connection of the oil vapour rebreathing circuit.
– The rail pressure regulator (MPROP) (jammed - stuck), apply the interpretation of command AC011 Rail
pressure regulator.
Check the engine timing (and the position of the high pressure pump sprocket). See the procedure in the
Workshop Repair Manual if necessary.
Test the high pressure fuel circuit:
Run the scenario SC035 High pressure fuel circuit fault finding (see Interpretation of commands).
If the fault is still present, contact the techline.

ALP5 Irregular engine operation
NOTESBefore analysing this customer complaint, check that there are no faults, and the
conformity (or otherwise) of the parameters and statuses, using the diagnostic
tool.
If the customer complaint is not eliminated, perform the following checks.
If the engine races during gear changes, if there is a floor carpet, check that this is not blocking the accelerator
pedal, the brake pedal and the clutch pedal, then check the conformity of the clutch switch and the conformity of
the accelerator pedal sensor when the pedal is released.
Measure the resistance of the engine speed sensor between the following connections:
– Connection code 3BG,
– Connection code 3BL,
of component 149.
Replace the sensor if the resistance is not 200 Ω to 270 Ω at +20°C
Check the continuity of the following connections:
– Connection code 3BG,
– Connection code 3BL,
between components120 and 149.
Check the conformity of the engine earths (oxidation, tightness, etc.).
Check the mounting and condition (overheating) of the sensor.
Replace if necessary.
Check the low pressure circuit, run test 3 Low pressure circuit check.
Apply the air flow test procedure (see Interpretation of statuses and Interpretation of parameters).
Check the turbocharger, apply the following tests:
– test 2: Air path at the turbocharger,
– test 6: Turbocharger control solenoid valve check,
– test 7: Turbocharger.
Test the high pressure fuel circuit:
Run scenario SC035 High pressure fuel circuit fault finding (see Interpretation of commands).
If the customer complaint is still present, contact Techline.
