Check the condition of the EGR valve (see Wiring Diagram Technical Note, Laguna II ph2, Vel Satis ph2,
Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 1460 or 169).
Check the condition of the engine management computer connector (see Wiring Diagram Technical Note,
Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 120).
If the connector or connectors are faulty and if there is a repair procedure (see Technical Note 6015A, Repairing
electrical wiring, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Measure the resistance between connections 3EL and 3JM of component 1460 or 169.
If the resistance of the EGR valve is not between 1 kΩ < X < 7,5 kΩ, replace the EGR valve.
Measure the resistance between connections 3EL and 3GC of component 1460 or 169.
If the resistance of the EGR valve is not between 3.9 kΩ < X < 12.6 kΩ, replace the EGR valve.
After replacement, run command SC036 Reinitialise programming and select EGR valve to reinitialise the EGR
valve offsets.
Check the continuity and absence of interference resistance of the following connections:
•3GC between components 120 and 1460 or 169,
•3EL between components 120 and 1460 or 169,
•3JM between components 120 and 1460 or 169.
If the connection or connections are faulty and if there is a repair method (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring,
otherwise replace the wiring.
Remove and clean the EGR valve, then refit the EGR valve and start the engine (see MR364 (Mégane II ph2),
