EGR valve with a square connector:
Measure the resistance of the EGR valve position feedback potentiometer between connections 3GC and 3JM.
Replace the EGR valve if the resistance displayed is not between 3.9 Ω < X < 9.1 Ω at 20°C.
EGR valve with a flat connector:
Replace the EGR valve.
If the valve is jammed or irrevocably seized, replace the EGR valve.
When replacing the EGR valve, run command SC036 Reinitialise programming and select EGR valve to
reinitialise the EGR valve offsets (see Replacement of components).

NOTESNone
Check the EGR valve connections.
Check the injection computer connections.
Repair if necessary.
Check the continuity and insulation from + 12 V of the following connections:
– connection code 3EL,
– connection code 3JM,
– connection code 3GC.
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 for + 5 V on connection 3GC of the EGR valve.
