INLET AIR TEMPERATURE
NOTESThere must be no present or stored faults.
Perform this fault finding procedure after noting an inconsistency in the Parameters
menu.
Check the air flow sensor.
Check the injection computer connections.
Repair if necessary.
Check for + 12 V on track 4 of the air flow sensor connector.
Display PR059 Inlet air temperature and check that the value displayed is not recovery value 20 °C.
If this is the case, check the coolant temperature sensor:
Injection computer brown 48-track connector B,
track G2Track 1 of the air flow sensor connector
Injection computer brown 48-track connector B,
track E2Track 2 of the air flow sensor connector
Repair if necessary.
Measure the resistance between tracks 1 and 2 of the air temperature and pressure sensor.
Replace the air temperature and pressure sensor if the resistance is not:
3,714Ω ±161Ω at 10 °C
2,448Ω ±96Ω at 20 °C
1,671Ω ±59Ω at 30 °C
AFTER REPAIRRepeat the conformity check from the start.

COOLANT TEMPERATURE
NOTESNo fault should be present or stored:
Perform this fault finding procedure after noting an inconsistency in the Parameters
menu.
Display the PR064 Coolant temperature and check that the value displayed is not recovery value -30°C.
If this is the case, check the coolant temperature sensor:
Check the condition of the coolant temperature sensor connections.
Repair if necessary.
Check for the absence of interference resistance on the following lines:
Brown 48-track connector B, track F2 Track 3 coolant temperature sensor
Brown 48-track connector B, track H1 Track 2 coolant 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 air temperature and pressure sensor if the resistance is not:
2,252Ω ± 112Ω at 25 °C
811Ω ±39Ω at 50 °C
283Ω ±8Ω at 80 °C
Replace the coolant temperature sensor if the values read do not correspond to the ones above.
AFTER REPAIRRepeat the conformity check from the start.

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
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.

ALP 4 Poor performance
NOTESBefore dealing with 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.
IMPORTANT
In the event of the engine overheating above 11 0 ° C, the computer deliberately limits the fuel flow, and supplies
the fan assembly until the battery is completely discharged.
Is the poor performance accompanied by smoke?
YES
Check:
– That the EGR valve is not jammed in the open position.
– That the injectors are properly mounted (presence and conformity of the sealing washer).
Is the engine running on all cylinders?
NO
Check that the injectors are operating correctly. (See Test 1)
If the fault is still present
Check the conformity of the accelerator pedal position sensor, the brake pedal sensor, the atmospheric pressure
sensor and the EGR valve.
– Check the condition of the air filter.
– Check the consistency of the signal: from the flow sensor or the pressure/air temperature sensor, engine coolant
temperature sensor, fuel temperature sensor, engine speed.
No foreign bodies on the flowmeter grille (visual inspection only).
Check:
– That the diesel filter is not clogged.
– That there are no leaks in the low pressure and high pressure diesel circuits;
– that the air inlet circuit is complete (sealed and not obstructed),
– That the oil vapour rebreathing system is connected.
– The flow regulator (jammed/seized, consult the interpretation of command AC011 Rail pressure
regulator).
– The turbocharger control (jammed / seized), consult the interpretation of command
AC004Turbocharging solenoid valve,
– Check the engine compressions (cylinder compression balance with the Compression test function on
the CLIP tool).
– Check that the exhaust pipe is not blocked.
NO
YES
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
