NOTESPriorities when dealing with a number of faults:
Deal with faults stored in the computer first.
Ask the customer about vehicle usage: driving style, type of journey, etc.
Conditions for applying the fault finding procedure to a stored fault:
The fault is declared present after the engine is started or following a road test.
Special notes:
If the fault is present:
– particle filter regeneration is inhibited,
– the EGR function is inhibited,
– the vehicle performance is reduced,
– the level 1 warning light is lit and a warning message (or light) is displayed on the
instrument panel.
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary.
Carry out an After-Sales regeneration (before and after each regeneration, check the oil and diesel fuel levels).
Run command SC017 Particle filter regeneration (see Interpretation of commands).
Use ALP 21: Particle filter warning light lit.
Deal with the interpretation of fault DF1003 Particle filter differential pressure sensor circuit.
Check the exhaust system.
Deal with the interpretation of fault DF1000 Particle filter upstream temperature sensor circuit.
Deal with the interpretation of fault DF1007 Catalytic converter 1 downstream temperature sensor circuit.
Deal with the interpretation of fault DF999 Particle filter downstream temperature sensor circuit.
Deal with the interpretation of fault DF652 Turbine upstream temperature sensor circuit.
Carry out Te s t 1 0: Air Chain at the level of the turbocharger.
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.
Explain to the customer how the particle filter system works.

Measure the resistance of the particle filter upstream temperature sensor, component code 1287 between
connections 3TD and 3XT.
If the resistance is not:
106170Ω 33550Ω < X < 33570Ω at 100°C,
6886Ω < X < 6906Ω at 200°C,
2565Ω < X < 2585Ω at 300°C,1192Ω 663Ω 277Ω replace the particle filter upstream temperature sensor (see MR 392, 385, 364, 370 and 417, Mechanical,
19B, Exhaust, Particle filter temperature sensors: Removal - Refitting).
Check the connection and condition of the connectors of the fuel pump, component code 218 and of the relay,
component code 236. With the ignition on, check the continuity, insulation and absence of interference resistance
on the following connections:

–3AHA between components 236 and 120,
–3FB between components236 and 983,
–BP1 between component 236 and + battery supply
.
If the connection(s) 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.
Check that the exhaust pipe is not cracked or pierced.
Check the effectiveness and condition of the oxidation catalytic converter and the particle filter.
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.

1. DEF: Micro-breaks
2. DEF: Signal outside lower limit
3. DEF: Signal inconsistency
NOTESConditions for applying the fault finding procedure to a stored fault:
The fault becomes present:
– with the ignition on (for status CC.0),
– after a road test with a warm engine (for status CO. 1).
Special notes:
If the fault is present:
– particle filter regeneration is inhibited,
– the level 1 warning light is lit,
– the OBD warning light illuminates after three consecutive driving cycles (starting + 5
seconds + switching off the ignition and waiting 1 minute).
IMPORTANT
The catalytic converter 1 downstream temperature sensor only measures
temperatures above 50°C.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and Kangoo II Wiring
diagrams Technical Note.
Run command AC029 High pressure circuit sealing test and check PR810 Catalytic converter 1
downstream temperature.
If the catalytic converter 1 downstream temperature is above 80°C, then the sensor is correct, otherwise continue
the fault finding procedure.
Check the connection and condition of the connector of the catalytic converter 1 downstream temperature
sensor, component code 1765.
If the connector is 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 connection and condition of the injection computer connector, component code 120 (see MR 392,
385, 364, 370 and 417, Mechanical, 13B, Diesel injection, Diesel injection computer: Removal - Refitting).
If the connector is 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.
Measure the resistance of the catalytic converter 1 downstream temperature sensor, component code 1765
between connections 3AGX and 3AGY.
6886Ω 2565Ω 1192Ω 414Ω at 600°C,
277Ω If the resistance does not match these values, replace the catalytic converter 1 downstream temperature
sensor.
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.

wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, replace the turbine upstream temperature sensor.
While the engine is idling, check the return flow rate at the injectors.
After 5minutes the return volume must be between 16 mland 24 ml per injector.
If this tolerance is incorrect, replace the faulty injector(s).
Check the temperature of the catalytic converter; check that it is not too low.
Check that the exhaust system is not pierced.
