PR131EGR AIR FLOW DIFFERENCE
PARAMETER
DEFINITIONThis parameter indicates the EGR air flow difference.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C
PR131 = PR146 – PR171
The value must be very close to 0.
In the event of a fault, consult the interpretation of fault DF056 Air flow sensor circuit.

Sensor electrical conformity
Test 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, run test 4 of ALP2: 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 feed to the air flowmeter.
– connection 3KJ of component 799.
Check the +12 V after relay feed to the air flowmeter.
– connection 3FB of component 799.
Check for continuity and absence of interference resistance of the following connections:
– connection code3DV,
– connection code3DW,
between components 120 and 799.
With the flowmeter connected, the vehicle ignition on and engine stopped:
Check the voltage between connections 3DW and 3DV of component 799.
– If the voltage is not approximately 0.6 V ± 0.1 V, replace the air flowmeter.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
