== 18891/P2459/009305 - Diesel Particulate Filer: Regeneration Frequency   ==

==== Possible Symptoms ====

* MIL on

==== Possible Causes ====

* Heavy loads on engine (towing)
* Short trips in cold weather
* Faulty Exhaust Pressure Sensors (G450/G451)

==== Possible Solutions ====

* Change driving habits.
* Inspect Exhaust Pressure Sensors (G450/G451) as per factory repair manual.

==== Special Notes ====

* Depending on driving habits, soot can build up quickly in the DPF, thus requiring more frequent regenerations than normal.
* With CBEA and CJAA engines, the factory documentation may show the wrong part location for the Exhaust Pressure Sensor 1 (G450).  This sensor is in a foil pouch just behind the oil cap.
