Code P244B RAM Description

The P244B diagnostic trouble code (DTC) specifically refers to a diesel particulate filter (DPF) differential pressure that is too high in Bank 1 of the vehicle's engine. The DPF is an essential component in reducing harmful emissions from diesel engines by trapping and storing particulate matter before it is released into the atmosphere. When the differential pressure across the DPF becomes too high, it indicates that the filter is becoming clogged with soot and other particles, hindering its ability to function effectively.
