Error codes/ FICM?
So while driving during a trip to the Deschutes River my check engine light came on. 2006 E350 6.0 Powerstroke. Stopped at a O'Reilly's and at Baxters and had them check the codes. All eight cylinders are showing a PO2 code (cylinder injector circuit low). Is it odd that all eight are coming up? Sounds like the module/ FICM is shot. Could it be an electrical issue? I am not noticing any rough engine signs or any unusual mileage loss. It just happened last night but I did have to drive 3 hours after this happened and did not notice a change in driving. Kind of worried. I am certainly not an experienced mechanic but would consider switching out the FICM myself it turns out to be the culprit. Thoughts would be awesome and welcomed. Thanks.

It could also be a failing alternator, or a bad battery. Or bad battery connection. Or a main harness fault. Or bad ground. Or as you suspect, a bad FICM. I'm not sure I'd replace it without further diagnosis.
If you start to see black smoke or sense a loss of power, don't keep pushing it, unless you want to earn yourself a full set of injectors in the process. Unfortunately, the time between "this is still ok" and "WTF is happening" sometimes isn't long.

It would be nice to figure out what the FICM voltage is? You want 48V and is of course a known failure point on the 6.0. This is where I would send it: https://www.ficmrepair.com/
Does it idle rough or is it hard to start?

Get a ScanGauge II, It will be the best addition to your 6.0 money can buy. It will show you all stored trouble codes along with FICM output voltage, which should be 48v, this is most likely your issue. Other than the Scan Gauge I am not sure how to test the FICM voltage without taking it to a shop with Ford IDS scan software. Hand scanners and Scangauge will not see any codes if they were deleted by the tester.
If it is low FICM output, it must be addressed right away or you risk injector damage. As stated by other members you should get your alternator tested. My Alternator went out at 70K and killed the FICM because I did not catch it in time.
The Scan Gauge will give you dozens of other temps and readings that must be monitored on the 6.0sss Like Oil temp vs Coolant temp, transmission temp, oil pressure and lots of others.
If the FICM tests out ok then you may have a wire harness short. I found wires rubbed through on the hood side and driverside doghouse.

I've been through all this. You need to to see a diesel specialist and have him hookup the laptop with the full on diagnostic software. It will tell you everything. I did replace my FICM and shortly after, all eight injectors. I had serious performance issues. I carry a spare FICM now. And my Scangauge II does not show me the FICM voltage. Why does yours? Maybe I don't know the setup?

It's an X-gauge command.
https://www.scangauge.com/x-gauge-commands/6-0l-diesel/
One thing of note, on the FICM it's usually the power supply and not the logic supply that goes bad. Generally you don't need both. So, buying the power supply side from Bulletproofdiesel is also an option but doesn't come with much of a warranty. Which is why I went the repair route.
Like HK33FAN said check those connection. Many are plastic and get quite brittle, including the connections to the FICM itself so you definitely want to be careful if you end up removing it. It's pretty easy to find and is under the degas bottle on the drivers side of the engine bay.

JEFFREY Check out JOEH's web link for a list of Xgauge codes. These are the codes used to program your ScanGauge, It takes a bit to set up, but once the codes are in, it's beautifully simple. you will need to download the owner's manual to navigate to the setup screen.
I have FICM, Oil temp, coolant temp, trans temp, fan speed, oil pressure, fuel pressure, and a few others programmed in. They are very easy to scroll through once programed.
The shop that testes your rig absolutely has to have the Ford IDS Factory software. It is the only one I know of that can run Injector uncompensated testing along with tons of other deep tests. I waisted a lot of money because of the shops without this software. I almost replaced injectors because my van was stuttering and missing. Turns out that my Fan clutch was taking a S#@T and was causing all kinds of gremlins. I am very close to just buying the IDS diagnostic software my self.
please report back your findings

My Scan gage II shows me my ficm voltage you just need to program it to do so...

FICM Voltage
Sorry for the slight highjack; is fluctuation between 47.5 to 48 volts to the FICM acceptable, or should I start to worry.

I usually reset codes at least once before I start any troubleshooting.
My reasoning is that I've seen codes appear after being tripped for various reasons that are not related to the actual code. If it comes back after the reset I then begin to troubleshoot.
It does help to have a good scanner and the scangauge ii.
