PR132AIR FLOW
PARAMETER
DEFINITIONThis parameter indicates the inlet air flow in kg/h.
NOTESThere must be no faults present.
Perform this fault finding procedure:
– after finding an inconsistency in the parameter,
– or after a customer complaint (lack of power, smoke etc.).
Use the Technical Note Wiring Diagram, Laguna II ph2, Vel Satis ph2, Mégane ll
ph2, Scénic ll ph2, Espace IV ph2.
Conformity check with engine stopped and ignition on.
The inlet air flow value must be:
PR132 = 0 kg/h.
Conformity check with the engine running and engine coolant temperature > 80°C
The inlet air flow value must be between:
20 kg/h < PR132 < 30 kg/h.

Sensor electrical conformity
Check the air inlet circuit (from the air filter inlet to the inlet manifold,
apply Test 4 Turbocharged air inlet circuit check):
– air filter unit inlet not blocked and filter not clogged,
–visual inspection only, apply Test 4 of ALP 2 Starting fault or starting impossible,
– oil vapour recirculation circuit connection conformity.
–absence of 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 not jammed closed.
Carry out the necessary repairs.
Check the electrical conformity of the air flowmeter:
Check the + 5 V supply of the air flowmeter on the following connection:
•3KJ of component 799.
Check the + 12 V after relay supply of the air flowmeter on the following connection:
•3FB of component 799.
Check the continuity and absence of interference resistance of the following connections:
•3DV between components 120 and 799,
•3DW between components120 and 799.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
With the flowmeter connected, the vehicle ignition on, and the engine stopped:
Check the voltage between connections 3DW and 3DV of component 799.
If the air flow sensor voltage is not between 0.3 V < X < 0.7 V, replace the sensor.
