Code P246C Dodge Description

The P246C diagnostic trouble code (DTC) specifically pertains to Diesel Particulate Filter (DPF) restriction, which results in the engine operating in a limited power mode. In diesel vehicles equipped with a DPF system, the filter traps and stores soot particles produced during the combustion process. Over time, the DPF can become clogged with excessive soot, leading to a restriction in exhaust flow and reduced engine performance.
