AIR FLOW
PARAMETER
DEFINITIONThis parameter indicates the inlet air flow in kg/h.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
No faults must be present.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– or after a customer complaint (lack of power, smoke etc.).
Conformity check with engine stopped and ignition on.
Indicates the inlet air flow in kg/h.
The value should be between:
0 kg/h < PR132 < 10 kg/h.
In the event of a fault, refer to the interpretation of DF056 Air flow sensor circuit.
Conformity check with engine running, engine coolant temperature > 80°C.
Indicates the inlet air flow in kg/h.
The value should be between:
Approximately 30 kg/h
In the event of a fault, refer to the interpretation of DF056 Air flow sensor circuit.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.

Sensor electrical conformity.
Test the air inlet circuit (from the air filter inlet to the inlet manifold tracts,
apply test 4 Turbocharged air inlet circuit check):
– air filter unit inlet not blocked and filter not clogged,
–visual inspection only, run test 4 Turbocharged air inlet circuit check for ALP2 Starting difficult or
impossible,
– oil vapour recirculation circuit connected correctly,
–absence of leaks or blockages in the low and high pressure air circuits: ducts, presence and tightness of the
mounting clips, mounting of the turbocharging pressure sensor, intercooler, etc.
– check that the damper valve is not jammed.
Carry out the necessary repairs.
Check the electrical conformity of the air flowmeter:
Check the + 5 V supply to the air flowmeter on connection 3KJ between components 120 and 799.
Check the + 12 V after relay supply to the air flowmeter on connection 3B between components 120 and 799.
Check the continuity and the absence of interference resistance on the following connections:
– connection code 3DV,
– connection code 3DW.
Between components 120 and 799.
If any of the connections are faulty and there is a repair method (see Technical Note 6015A, Electrical wiring
repair, Wiring: precautions for repairs), repair the wiring; otherwise replace the wiring.
With the flow meter connected, the vehicle ignition on and engine stopped:
Measure the voltage between connections 3DV and 3DW between components 120 and 799.
Replace the air flowmeter if its voltage is not approximately 0.5 V < PR073 Air flowmeter supply voltage < 0.7 V.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
