RAIL PRESSURE
NOTESPerform this fault finding procedure:
– after the interpretation of fault DF053 Rail pressure regulation function,
– after an inconsistency for PR038 noted in the Parameters menu,
– after the interpretation of the fault finding procedure for AC011 Rail pressure
regulator,
– following a customer complaint (starting faults, poor performance, stalling, etc.).
Check the continuity and the absence of interference resistance on the following connections:
Injection computer, brown 48-track connector
B, track G3Track 2 of the rail pressure sensor connector
Injection computer brown 48-track
connector B, track A4Track 3 of the rail pressure sensor connector
Injection computer, brown 48-track connector
B, track C4Track 1 of the rail pressure sensor connector
If all these connections are correct, check for fuel pressure sensor power supply:
+ 5 V Track 3 of the rail pressure sensor connector
Earth Track 1 of the rail pressure sensor connector
Repair if necessary.
Check the sealing of the low and high-pressure diesel circuits (visual inspections, odour) pump housing,
overpressure valve, pipes, rail and injector unions, injector wells, etc.
If all of the previous checks are correct, switch the ignition on, wait for more than 1 minute and display PR038 Rail
pressure.
If the value is less than 50 bar, the rail pressure sensor is correct. If it is greater than this value, replace the rail
pressure sensor and tighten it to 35 ± 5 Nm.
AFTER REPAIRRepeat the conformity check from the start.

FUEL TEMPERATURE
NOTESThere must be no present or stored faults.
NOTE
In the event of a relatively low outside temperature, the difference between the
fuel temperature and the engine temperature after cold starting may be greater
than 30 °C.
Check in the Fuel circuit tab in PR063 Fuel temperature that the value displayed is not the recovery value 100 °C.
If it is, check the fuel temperature sensor:
Check that the fuel temperature sensor is in good condition:
Repair if necessary.
Check the continuity and the absence of interference resistance on the following lines:
Brown 48-track connector B, track H2 Track 1 fuel temperature sensor
Grey 32-track connector C, track F1 Track 2 fuel temperature sensor
If the temperature read is inconsistent, check that the sensor follows the resistance as a function of temperature
calibration curve (NTC) correctly.
Replace the fuel pressure and temperature sensor if the resistance is not:
2,051 ± 123Ω at 25 °C
810 ± 47Ω at 50 °C
309 ± 17Ω at 80 °C
Replace the fuel temperature sensor if it is incorrect (an incorrect sensor is often the result of an electric shock).
AFTER REPAIRRepeat the conformity check from the start.

RAIL PRESSURE REGULATOR
NOTESThis command enables the operation of the injector high-pressure regulator circuit to
be checked.
Step 1
Measure the pressure regulator resistance between tracks 1 and 2.
– Replace the regulator if the resistance is not approximately: 3Ω ± 0.5 at 20 °C.
Check the continuity and the absence of interference resistance of the following connections:
Injection computer brown 48-track connectorB, trackM4 track 2 of the rail pressure regulator
connector.
+ 12 V after relaytrack 1 of the rail pressure regulator
connector.
If, when running command AC011, you can hear a slight whistling noise and the rattling from the regulator, go to
Step 2. Otherwise, ensure that the computer output is functioning correctly:
●Using a voltmeter:
With the solenoid valve connected, connect the voltmeter earth lead to track 2 of the fuel pressure solenoid valve
and the positive cable to track 1. Clear any fuel pressure solenoid valve faults, then run command AC011:
The voltmeter should display two successive voltages: ~ 2.5 V for an OCR at 20 % then ~ 8.75 V at an
OCR at 70 % (ten cycles)
●Or using an oscilloscope (range 5 V/division and with time base 1 ms/division):
With the solenoid valve connected, connect the earth of the oscilloscope to the battery earth and the positive test
pin to track 2 of the fuel pressure solenoid valve. Clear any fuel pressure solenoid valve faults then run command
AC011:
The oscilloscope should display a square-wave signal of 12.5 volts amplitude at a frequency of 185 Hz
(with an OCR going successively from 20 to 70 %).
– If the measurement is correct, replace the regulator.
– If the measurement is not correct, contact the Techline.

ALP 2Starting faults
(or starting impossible)
NOTESBefore dealing with this customer complaint, check that there are no faults,
and he conformity (or otherwise) of the parameters and statuses using the
diagnostic tool.
If the customer complaint is not eliminated, perform the following checks.
Is starting difficult or impossible?
difficult
Check the engine earths.
Make sure that the engine speed reaches 250 rpm when the starter motor is operated, displayed in
the parameter screen.
Ensure that the correct fuel is being used. Run test 5 Diesel fuel conformity check.
Check the conformity of the fuel filter connections.
Ensure that the fuel filter is not saturated with water.
Check there are no air bubbles between the filter and the high pressure pump.
Check the operation of the preheating unit and heater plugs with command AC001 Preheating unit.
Check the condition of the air filter (clogging).
Check the seal of the high-pressure diesel circuit, pump, pipes, unions (visual checks + odours).
Check the position of the EGR valve: jamming or mechanical seizure.
Check the consistency of the signal from the engine coolant temperature sensor.
Check that the pressure regulator is working correctly (see the interpretation of command AC011 Rail
pressure regulator).
Check the operation of the injectors (too much return leakage, clogging, seizing) referring to Component
test, Test 1 Injector Test.
Check the compression balance, according to current consumption during the starting phase
(Compression test menu on the Clip tool).
In the event of imbalance, use a compression gauge to refine the reading (see the procedure in the Workshop
Repair Manual). After the operation, clear the faults caused by disconnecting the regulator and the heater
plugs.
impossible
