The light may stay on or light intermittently as the DPF regenerates. The engine will be sluggish on acceleration.

Possible Causes :

Low fuel pressure caused by a clogged filter, failing fuel pump, failed fuel pressure regulator or clogged or leaking injectors.

Rough running engine due to misfiring plugs. Many engines have misfire codes to indicate the cylinder effected, such as P0307 for number 7.

Repair Processes :

Look for damage to the tank indicating impact that may have damaged the fuel pump or sender. If all testing has passed so far yet you still have the same code, check your scan tool and see if it can open and close the IMRC valve.
