P244C indicates that the engine control module has determined the exhaust gas temperature at the bank 1 particulate filter is too low to support an active regeneration cycle. The module monitors temperature sensors before and after the filter and sets this code when the measured temperature fails to reach the threshold required to burn off accumulated soot.
