P244F Meaning
The Powertrain Control Module (PCM) monitors conditions necessary for diesel particulate filter regeneration. During vehicle operation, if the diesel particulate filter temperature exceeds a calibrated limit, the PCM records how long the temperature remains above the limit. The test fails when the temperature before or after the diesel particulate filter exceeds the calibrated limit for more than 120 minutes during the filter’s lifetime.
