PR382PARTICLE FILTER UPSTREAM TEMPERATURE
PARAMETER
DEFINITIONThis parameter indicates the exhaust gas air temperature upstream of the particle filter
in °C.
NOTESThis parameter exists only on F9Q816 engines
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C, without electrical consumers
PR382 ≈ 200°C
In the event of a fault, consult the interpretation of faults DF309 Particle filter downstream temp* sensor circuit
and DF310 Particle filter upstream temp* sensor circuit.

PR383WEIGHT OF SOOT IN PARTICLE FILTER
PARAMETER
DEFINITIONThis parameter indicates the weight of soot contained in the particle filter in g.
NOTESThis parameter exists only on F9Q816 engines
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature

PR383 < 70 g.
If the weight is greater than 70 g carry out an After-Sales regeneration.
Check that there are no leaks or blockages in the exhaust pipe,
Repair if necessary
Run command SC017 Particle filter regeneration and follow the procedure (see Interpretation of commands).
In the event of a fault, refer to the interpretation of fault DF315 Particle filter diff* pressure sensor.
