P2463 Diesel Particulate Filter Restriction Soot Accumulation. By exceeding the second threshold for a sufficient period of time a wrench light and a mil will be illuminated and engine output will be limited and egr is disabled. Because dpf systems are designed to remove ninety percent of carbon particles soot from diesel engine exhaust soot accumulation can sometimes lead to dpf restriction.
This code should be exhibited only in diesel powered vehicles. By exceeding the first threshold for a sufficient period of time a wrench light will be illuminated. The monitor compares the calculated restriction of the dpf to two thresholds.
By exceeding the second threshold for a sufficient period of time a wrench light and a mil will be illuminated and engine output will be limited and egr is disabled.
By exceeding the first threshold for a sufficient period of time a wrench light will be illuminated. Note that the amount of soot that constitutes an excessive load varies between manufacturers and applications on the one hand and that the. Obd ii fault code p2463 is a generic code that is defined as diesel particulate filter restriction soot accumulation and is set on all diesel applications when the pcm powertrain control module detects an excessive accumulation of solid particulate matter diesel soot in the diesel particulate filter. What does code p2463 mean.
