P244EExhaust Temperature Too Low For Particulate Filter Regeneration Bank 2

P244E is a generic powertrain code indicating that the engine control module has determined the exhaust gas temperature on bank 2 is too low for the diesel particulate filter to perform a regeneration. The computer monitors bank 2 exhaust temperature sensors and compares the measured value against the minimum threshold required to burn off accumulated soot, and it sets this code when the temperature stays below that threshold for a calibrated period.
