A device for diagnosing a particle filter attached onto a main exhaust line of an internal combustion engine, wherein the diagnosis device includes, downstream from the first particle filter, a detection filter and a sensor for measuring an output parameter of the detection filter. The detection filter is arranged in a secondary exhaust line through which a first portion of the gases from the particle filter passes, wherein a second portion of the gases from the particle filter follows the main exhaust line. The device can be used for diagnosing particle filters for an automobile having a combustion engine. |
