NOTESConditions for applying fault finding procedures to stored faults:
The fault becomes present if:
– ignition is on (CC.0),
– following a road test, engine warm (CO.1).
Special notes:
If the fault is present:
– particle filter regeneration is inhibited,
–the level 1 warning light is lit,
– the EOBD (European On Board Diagnostic) warning light will come on after three
consecutive driving cycles (starting + 5 seconds + switching off the ignition and
waiting for 1 minute).
IMPORTANT:
The particle filter upstream temperature sensor only measures temperatures above
50°C.
CC.0
NOTESNone.
Check the condition of the particle filter upstream temperature sensor connector (see Wiring Diagram Technical
Note, Laguna II ph2, Vel Satis ph2, Espace IV ph2, Mégane II ph2, Scénic II ph2, component code 1287).
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 there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check the insulation from earth of the following connections:
•3XT between components 120 and 1287,
•3TD between components 120 and 1287.
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.
