DPF differential Pressure problems

[Rawze]

* Sometimes the tubes for the DPF Diff. pressure sensor (DPF Delta-P sensor) down at the DPF will clog up, or the rubber boots where they meet the sensor get cracked.

* sometimes the DPF itself is simply cracked and is restrictive.

* sometimes it is due to someone changing the ECM software in an attempt to "uprate" the power incorrectly.

* Sometimes the computer simply gets confused and will flag it after it has been cleaned, making the alarms more sensitive.

* sometimes it is bad readings from other sensors and/or a stuck EGR valve causing excess soot.

* sometimes it is coolant or oil intrusion.

* Sometimes it is simply the fact that the DOC or DPF is very old and the chemicals in them have been washed out.
