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
EGR valve with a square connector:
Measure the resistance of the EGR valve between the following connections:
– Connection code 3JM of component 1460.
– Connection code 3GC of component 1460.
EGR valve with a flat connector:
Replace the EGR valve.
Replace the valve if the resistance is not between: 3.9 kΩ When replacing the EGR valve, run command SC036 Reinitialise programming and select EGR valve to
reinitialise the EGR valve offsets (see Replacement of components).
