PARTICLE FILTER TEMPERATURE SENSOR FAULT FINDING
NOTESCarry out this command only under the following conditions:
– DF999 Particle filter downstream temperature sensor circuit,
– DF1000 Particle filter upstream temperature sensor circuit,
With the ignition on and engine switched off and the engine coolant temperature
below 40°C.
This command is used to check the operation of the particle filter temperature sensors.
Use CLIO III, MODUS, MEGANE II ph2, SCENIC II ph2 and KANGOO II Wiring
diagrams Technical Note.
If one of the faults such as DF999 Particle filter downstream temperature sensor circuit or DF1000 Particle
filter upstream temperature sensor circuit is stored, check if it is in short circuit to the + 12 V or in open circuit
using this command.
Procedure:
– Run command AC239 Particle filter temperature sensor fault finding in the presence of the one of these
two faults DF999 Particle filter downstream temperature sensor circuit and/or DF1000 Particle filter
upstream temperature sensor circuit.
– If one or both of these faults becomes present, then the sensor(s) is in short circuit to + 12 V or in open
circuit.
Refer to the interpretation of faults DF999 Particle filter downstream temperature sensor circuit and DF1000
Particle filter upstream temperature sensor circuit.
– If they do not become present, clear the faults on the CLIP diagnostic tool.
