NOTESConditions for applying the fault finding procedure to
a stored fault:
The fault is declared present after the ignition has been
switched off for 15 seconds.
Check the air flowmeter connections.
Check the injection computer connections.
Repair if necessary.
Check the continuity and absence of interference resistance of the following connections:
Injection computer, brown 48-track connector B, track B4 Track 3 air flow sensor
Injection computer brown 48-track connector B, track G1 Track 5 air flow sensor
Injection computer, brown 48-track connector B, track L4 Track 6 air flow sensor
Injection computer, brown 48-track connector B, track E2 Track 2 air flow sensor
Injection computer, brown 48-track connector B, track G2 Track 1 air flow connector
PPM1 black connector of the UPC track 2 Track 4 air flow sensor connector
Repair if necessary.
Check the entire air inlet circuit:
– air filter unit inlet not blocked and filter not clogged,
–no foreign bodies on the air flow sensor grille (visual inspection only).
Otherwise, replace the air flow sensor.
– oil vapour recirculation circuit connected correctly,
–no leaks or blockages in the low and high pressure air circuits: pipes, presence and tightness of the mounting
clips, mounting of the turbocharger pressure sensor, intercooler, etc.
– check that the damper valve is open (valve control is against the body of the air vent unit).
With the flowmeter connected, the vehicle ignition on and engine stopped:
– check the voltage between tracks 2 and 5 of the flowmeter:
If the value is not 0.6 V ± 0.1, replace the air flow sensor.
AFTER REPAIRDeal with any faults.
Carry out a road test followed by a 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.

ALP 7 Oil leaks from the turbocharger
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.
Check the area around the turbocharger
Note:
An oil leak does not correspond always to a turbocharger fault, the oil leak can arise from the area around
the turbocharger.
Depending on the vehicle type, the best visual access will be either from above or from below.
1-Do not start the engine.
Check the area around the turbocharger and identify the origin of the leaks.
Clean the oil traces on the turbocharger.
2- Start the engine and let it warm up for several minutes.
IMPORTANT
If the air filter was removed previously, refit it before starting the engine (risks foreign matter entering the air inlet
circuit).
Accelerate with no load several times, progressively increasing the duration before releasing the accelerator
pedal.
Visually inspect the exterior condition of the fuel supply pipes and the turbocharger oil return and the area
around it.
Identify the origin of the leaks.
Is an oil leak present at the air compressor inlet or outlet?
YES
NO
AFTER REPAIRCarry out a road test followed by a complete check with the diagnostic tool.
