Check the connection and condition of the EGR valve connector, component code 1460.
Check the connection and condition of connector B (brown 48-track) of the computer, component code 120.
If the connector(s) is 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.
Check the insulation and continuity of the following connections:
–3GC between components 1460 and 120,
–3EL between components 1460 and 120,
–3JM between components 1460 and 120.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Check for + 5 V on connection 3GC of component 1460.
Check for earth on connection 3JM of component 1460.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Measure the resistance of the EGR valve, component code 1460:
–with the engine stopped, the exhaust gas recirculation valve will be closed (unless there is a fault),
–wait for the ambient temperature around the valve to stabilise (approximately 20
°C),
measure the resistance between connections 3VP and 3VQ of component 1460. The resistance must be between
0.5 ΩΩ Ω Ω
< R < 50 Ω (while running command AC002 EGR solenoid valve).
If the value is not correct, replace the EGR valve (see MR 364 (Mégane II), MR 370 (Scénic II), MR 385 (Modus),
MR 392 (Clio III), MR 411 (New Twingo), MR 417 (Kangoo 2), Mechanical, 14A, Emission control, Exhaust
gas recirculation solenoid valve: Removal - Refitting).
After replacing the EGR valve, use command RZ002 EGR Adaptives to reinitialise the EGR valve offsets.
If the fault is still present, contact the Techline.
