Need help, truck in limp mode multi codes
I have a 2012 F350 6.7 Diesel 120,000 miles.
Vehicle in limp mode
Service lights on:
Service Adv Trac –
Hill Descent control fault
Wrench
Codes lit:
P2426 – Exhaust Gas Recirc Cooling Valve
P208B Reductant Pump A Control Range/Performance
P208C Reductant Pump Control Circuit low
P20A2 Reductant Purge Control Valve Circuit Low
P0245 Turbo wastegate solenoid A low
P132A Turbo Boost control A electrical
Stuff I did so far:
New batteries, added a tune to remove the DPF/EGR, and no change.
I found that the Fuses 33-37 has only 2 volts? I heard the fuse 34 VPWR 2 controls those codes? Does anyone know what the issue can be?

so, I assume this truck is dpf deleted (and u say EGR too)..
why wouldn't it have already had a tune applied?
what tuner?
sounds like three problems
1 dpf/egr/scr expected to be there, but not
2. turbo.. maybe wiring, not plugged in?
3. hilll decent/advancetrack.. the sensor not plugged in or wiring problem.
where did u get the truck, when, was it like this when u got it..
or when did thee codes start.. what happened right before that
a little more info please

Update: I found fuse #34 VPWR2 is blown. And keeps blowing when I put a new on in, so I must have a short some where. VPWR2 powers all the codes I listed out above.
History: I had my truck for 3yrs, no issues, w/ SCT tune w/ DPF/EGR. I just bought a mini max this week and will start to update the truck, but needed these issues fix first. Thx in advance.

F350 fuse 34 issues
I have the same problem and same truck and same setup as the guy that started the thread. My fuse keeps blowing. Keeps happening more often. If I am deleted, can I just unplug the DPF to eliminate any possible shorting that could be causing this?

Yes, mine is removed and all these are unplugged. I have had my truck for years with the tune and delete. Never had issues until recently with the fuse 34. Seems to be getting worse. Happening more frequently. Taking to a mechanic tomorrow after looking over the wiring and not seeing any obvious issues. Any ideas or suggestions?

If you are blowing out a fuse, it points to a short in the wiring / circuit (since it just began, most likely not caused by the tune / delete). Visual inspection sometimes isn't sufficient, as it could also be in the connectors on either end or wires that have chaffed and are wrapped, hampering your ability to see the shorted area. Is there any chance water / moisture has gotten in the fusebox? Hopefully the mechanic will be able to locate and correct.
