P2002 Meaning
The diesel particulate filter (DPF) is monitored for conditions where it may become overloaded. The monitor compares the calculated DPF restriction to two thresholds. Exceeding the first threshold for a sufficient period of time will trigger a key light. Exceeding the second threshold for a sufficient period of time will trigger both a key light and MIL, and engine power will be limited while EGR is disabled.
