Code P246C Ford Description

The Diesel Particulate Filter (DPF) is monitored for conditions where it may be overloaded. The monitor compares the calculated restriction of the DPF to two thresholds. By exceeding the first threshold for a sufficient period of time, a wrench light will be illuminated. 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.
