Hello, I drive a 2012 peterbilt 386 and I have been experiencing lower mpg than usual and the truck asks for the regeneration to be perform at shorter time periods. When I place the truck in relay the truck feels like it is accelerated similar to when performing a regeneration. Cummins has determined that all of the DPF filters sensors are working but they cannot determine the condition of the filter or catalytic converter. Any help with this issue is appreciated.
