PARTICLE FILTER UPSTREAM TEMPERATURE SENSOR CIRCUIT
CC.0 : Short circuit to earth
CO.1 : Open circuit or short circuit to +12 V.
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 particle filter upstream 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 PR382 Particle filter upstream
temperature.
If the particle filter upstream temperature is above 50°C, then the sensor is correct, otherwise continue the fault
finding procedure.
Check the connection and condition of the connection of the particle filter upstream temperature sensor,
component code 1287 (see MR 392, 385, 364, 370 and 417, Mechanical, 19B, Exhaust, Particle filter
temperature sensors: 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.
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.
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.

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.

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.
