Cummins isx 15 CM2250 silent derate
I have a 2013 CM2250 Cummins in a Peterbilt 579 750,000 that has power loss. Engine was inframed 25,000 miles ago and deleted as well. Truck tripped a check engine light on and then derated. FMI codes 2346 and 2451 last week, 3/3/20.
Replaced with IMAP and turbo inlet temperature sensors. Check engine light has been cleared but truck is still derated with code 2346 staying inactive. FYI truck was fully serviced and a exhaust leak was repaired on DPF then the next day is when this issue happened. The VGT test was completed and passed as well. Intake and fuel system has been checked. Truck does well shifting through low side of transmission but has hardly any boost on the high gears. Any advised? Thanks
