DTC code P2002: DPF efficiency below threshold
P2002 means the diesel particulate filter isn’t trapping soot as well as it should. Short trips that prevent full regeneration cycles cause it most often. A cracked filter or a failed pressure sensor can talso Power drops, regenerations happen more often, and fuel use goes up.
Intangles tracks regeneration cycles and soot load across a fleet, helping schedule the right driving conditions or service before the filter falls behind. Want to see how? Share your email to get started.
