PR381PARTICLE FILTER DOWNSTREAM TEMPERATURE
PARAMETER
DEFINITIONThis parameter indicates the exhaust gas air temperature downstream of the particle
filter in °C.
NOTESThis parameter exists on certain vehicles with Vdiag48 (depending on equipment). If
the vehicle is not equipped with this sensor, the default value is PR381 = 50°C
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
> 80°C, without electrical consumers
PR381 ≈ PR382 Particle filter upstream temperature ≈ ± 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.
