NOTESConditions for applying the fault finding procedure to a stored fault:
The fault is declared present with the engine at idle speed.
Special notes:
EGR cut off.
If the fault is present:
– engine instability, possibly even stalling,
– engine starting is difficult or even impossible when cold,
– the OBD warning light is on.
Use the Wiring Diagram Technical Notes for CLIO III, MODUS, MEGANE II ph2,
SCENIC II ph2 and KANGOO II.
Check the connection and condition of the EGR valve connector, component code 1460 and check the connector
for the injection computer, component code 120.
If the 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.
Check for the presence of the supply: 13 V < X <14 V (engine running), 11.5 V < X < 12.5 V (ignition on,
engine stopped) on connection 3VP of component 1460.
Check for earth on connection3VQ of component1460.
Check the continuity, insulation and the absence of interference resistance on the following connections:
–3VP between components 1460 and 120,
–3VQ 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 it.
Measure the resistance of the EGR valve, component code 1460:
– with the engine stopped, the EGR valve will be closed (unless there is a fault),
– wait for the ambient temperature to stabilise (approximately 20 ºC) around the valve,
– measure the resistance between connections3VP and 3VQ of component1460.
If the resistance is not between 0.5 Ω < X < 50 Ω, replace the EGR valve (see MR 392 (CLIO III), 385 (MODUS),
364 (MEGANE II), 370 (SCENIC II), 417 (KANGOO II), Mechanical, 14A, Emission control, Exhaust gas
recirculation solenoid valve: Removal - Refitting
).
Use the command RZ002 EGR Adaptive to reinitialise the offsets of the EGR valve (see Replacement of
components).
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any faults displayed by the diagnostic tool.
Clear the computer fault memory.
Carry out a road test followed by another check with the diagnostic tool.
