FIRST EGR VALVE OFFSET
PARAMETER
DEFINITIONThis parameter indicates the closing ratio of the EGR valve for the first offset of the EGR
valve.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system
operation programming.
Conformity check with the engine stopped and the ignition on, or the engine running and the engine
coolant temperature > 80°C
Indicates the percentage ≈ 20%.
PR128 ≈ PR129 Last EGR valve offset, these 2 values should be similar.
In the event of a fault, consult the interpretation of faults DF209 EGR valve position sensor circuit and DF647
EGR valve position regulation.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

CRUISE CONTROL SETPOINT
PARAMETER
DEFINITIONThis parameter indicates the cruise control speed setpoint in mph (km/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:

– or after a customer complaint (lack of power, smoke etc.).
Conformity check with the engine stopped and the ignition on, or engine running, and engine coolant
temperature > 80°C
Indicates the cruise control cruising speed.
Cruise control can only be activated for a speed.
V > 18 mph (30 km/h)
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.

AIR FLOW
PARAMETER
DEFINITIONThis parameter indicates the inlet air flow in mg/st.
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.).
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
Diagrams Technical Notes.
Sensor electrical conformity
Check the air inlet circuit (from the air filter inlet to the inlet manifold, run test 10 Air line at the turbocharger):
– air filter unit inlet not blocked and filter not clogged,
–visual inspection only, use ALP2 The engine does not start or starts with difficulty,
– 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, exchanger, etc.
– check that the damper valve is not jammed shut (except Vdiag 4C).
Carry out the necessary repairs.
Check the electrical conformity of the air flow sensor:
Check the + 5 V supply to the air flowmeter.
– connection 3KJ of component 799.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
