Abstract:
A method and system are provided for assessing engine faults. The method includes measuring actual diesel particulate filter (DPF) soot loading, determining expected DPF soot loading, aid determining that a possible engin component fault is an actual engine component fault by determining that measured actual DPF soot loading exceeds the expected DPF soot loading.
