5.DEF: Valve jammed closed
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after:
– the engine is started,
– a road test.
Special notes:
If the fault is present:
–the level 1 warning light is illuminated for 1.DEF, 3.DEF and 5.DEF,
–the European On Board Diagnostic warning light is illuminated for 2.DEF and
4.DEF,
– the EGR function and turbocharging are inhibited by the engine management
computer,
– engine torque is limited.
Use bornier Ele. 1681 for all operations on the engine management computer
connector.
If faults DF647 and DF038 Computer are displayed at the same time, deal with DF038
Computer first. Then check that the EGR valve is open during idling to make sure that
the programming has not been lost. If the valve does not open, carry out the
programming phase.
Priorities when dealing with a number of faults:
– DF209 EGR valve position sensor circuit,
– DF046 Battery voltage,
– DF012 Sensor supply voltage no. 2,
– DF272 EGR valve control circuit,
if they are present or stored.
For EGR valves with a flat connector, it is not possible to check the sensor resistance.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.

NOTESCarry out this fault finding procedure when the interpretation of fault DF304 EGR
bypass circuit has not been resolved.
Ignition on and engine stopped.
Use Wiring Diagram Technical Note, Mégane II ph2, Scénic II ph2.
Measure the resistance of the EGR bypass solenoid valve between the following connections:
– Connection code 3TP,
– Connection code 3FB,
of component 1301.
43 Ω to 49 Ω at +25°C.
32 Ω to 37 Ω at -40°C
If the resistance is not correct, replace the EGR by-pass solenoid valve.
Check the continuity, insulation and absence of interference resistance on the following connections:
– Connection code 3TP between components 1301 and 120.
– Connection code 3FB between components 1301 and 983.
If there is a repair method (see Technical Note 6015A, Repairing electrical wiring, Wiring: Precautions for
repair), repair the wiring, otherwise replace it.
If you notice no valve movement when running command AC103, ensure that the computer output stage is
functioning:
Vehicle under + after ignition feed, clear the faults displayed by the diagnostic tool.
With the voltmeter in the direct current position:
With the EGR BY-PASS solenoid valve connected, connect the voltmeter earth lead to connection3TP of
component1301 and the positive lead to connection3FB.
Run command AC103, the voltmeter should display four successive readings which are approximately equal to
the 12 V battery voltage.
If the voltmeter indicates no control or a continuous voltage, contact the Techline.
If activation has run correctly, check the control vacuum:
– Disconnect the solenoid valve inlet hose and connect it to a pressure gauge.
– Start the engine and run it at a stable idle speed.
– If the vacuum pressure does not reach 800 mbar ± 100: check the vacuum pressure circuit from the vacuum
pump.
Repair if necessary.
