Lighting bolt been on for a while, driver says loose power. Active codes MID 128 PPID 270 FMI 9, MID SID 27 FMI 9, MID 128 PSID 232 FMI, all 255 times. Inactive code MID 128 SID 27 FMI 2, 255 times. Could this be caused by 1 problem, which sould look at first. Light stays on all time. Is the Is the ppid 270 the last sensor in the exhaust pipe? Thanks

This is a GU713

MID 128 PPID 270 FMI 9 Nox sensor

MID 128 SID 27 FMI 9 Turbo VGT

MID 128 SID 27 FMI 2 Turbo VGT

MID 128 PSID 232 1939 datalink

Ive been out of the dealer for awhile but here is my guess.

Remove the VGT actuator from turbo. If turbo lever moves freely, replace actuator. If lever doesnt move, replace the complete turbo. Calibrate turbo.

Replace the Nox sensor.

Remove radio from datalink. The radio could cause 1939 datalink problems

Update all softwares. Updating softwares could resolve datalink problems.

Clear codes, road test and recheck.

No malfunction lights, truck runs normal, release truck.

The PSID:232 is the J1939 can2 datalink. All the components on that datalink are faulting. Check the EECU connectors for oil contamination, if so then clean it out. Check the VGT connectors for fretting--a powdery type residue that looks like rust. Check chassis wiring to and around the NOX sensor(s) for damage to the J1939 CAN2 wires (yellow and green twisted wires). Make sure that fuses 41 and 46 are ok for pre-SCR systems.

The FMI:2 is data erratic and FMI:9 is data absent, if the VGT harness connector shows signs of fretting then the connector pins need to be replaced. A common problem area is at the chassis to DPF harness connector. They are sometimes tied to the frame mount below the DPF and the wires can vibrate and break.
