Excessive overload of CDPF (warning lamp illuminated)
1.
If the vehicle is driven at a speed of 5 to 10
km/h for an extended period of time, the soot
accumulated in the CDPF cannot be burned
as the CDPF cannot reach the regeneration
temperature. Then, an excessive amount of
soot can be accumulated in the CDPF.
This case is much worse than the simple over-
2.
load of the CDPF. To inform this to the driver,
the engine warning lamp comes on and the
engine power is decreased to protect the
system.
To solve this problem, blow soot between the
3.
engine and exhaust system several times and
erase the related DTC. Then, check if the
same DTC is regenerated again. If so, check
the DTC related to the differential pressure
sensor.
