Same happened to me this afternoon: engine malfunction warning and limp mode! Pulled over and scanned: DTC P2002C - DPF efficiency below threshold The DPF_LOAD gauge was at 0% and DPF_SOOT_LD at 32%. Some time later after restarting the DPF_LOAD value was 43%. Did some googling and found this interesting forum post, post #4: http://www.thedieselstop.com/forums/...2-code-311269/ The DPF_LOAD value is calculated by the pcm from various input data from the engine management system etc. In other words it's what the pcm thinks it should be. On the other hand DPF_SOOT_LD is inferred from the pressure differential across the DPF. Anyway I took a look at the hoses to the pressure sensor and they were fine. I'll keep driving it as is, on the assumption that there has been a glitch, or else an intermittent sensor/circuit fault. |
