P244D - OBD II Trouble Code

Our automotive experts have put together the following information about the P244D diagnostic trouble code. We've provided the common symptoms that occur when this code is set along with the frequent repairs that address the issues related to the P244D code.

OBD II Fault Code

• OBD II P244D

OBD-II Code Decreased engine performance is defined as a Exhaust Temperature Too High For Particulate Filter Regeneration

Diesel Exhaust Fluid (DEF) is used to assist in converting leftover exhaust particles to harmless gases. In order to burn off those particles, the temperature of the exhaust system needs to increase. the injection of DEF Fluid into the exhaust stream brings Diesel Particulate Filter (DPF) up to temperature. The system is then able to convert harmful NOx to Nitrogen, Carbon Dioxide, and water. The Reductant Catalyst (SRC) was added to further reduce any NOx was still in the exhaust stream. If the temperature of the filter gets too high, the DPF cannot perform the regeneration process. Code P244D will be set.
