NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present the EGR function is disabled.
If 1.DEF is present, the level 1 warning light is lit.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
Priority when dealing with a number of faults:
–DF272 EGR valve control circuit if it is present or stored.
IMPORTANT
This fault can result in a rapid and significant fouling of the particle filter.
If dealing with this fault requires the EGR valve to be replaced, run command SC036
Reinitialise programming and select EGR valve to reinitialise the EGR valve offsets
(see Replacement of components).
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
Check for continuity and absence of interference resistance of the following connections:
- connection code 3VP,
- connection code 3VQ.
between components 120 and 1460.
If the connection or connections are faulty and there is a repair method (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check that there are no leaks on the EGR circuit, pierced or damaged pipes, and the tightness of the clips.
Measure the resistance of the EGR valve motor between connections 3VP and 3VQ.
Replace the EGR valve if the resistance displayed is not between 1 Ω < X < 400 Ω at 20°C.
If the valve is jammed or irrevocably seized, replace the EGR valve.
Run command SC036 Reinitialise programming and select EGR valve to reinitialise the EGR valve offsets (see
Replacement of components).
AFTER REPAIRDeal with any faults.
Carry out a road test followed by another check with the diagnostic tool.

NOTESConditions for applying the fault finding procedure to a stored fault:
The fault becomes present after an attempt to start.
Special notes:
If the fault is stored, clear the fault from the computer memory.
Switch off the ignition, start the engine and check that the fault does not reappear.
Use bornier Elé.1681 or Elé.1590 for any operation on the injection computer
connectors.
Check the engine speed sensor and camshaft sensor connections.
