Error codes

Asking for help with codes, PO264,PO267,PO273,PO282-codes refer to low circuits on injectors 2-3-5-8. PO402-excessive exhaut gas flow and PO611 Fuel injector control module performance. I have a 2006 F-250 6.0, one person thinks all codes may be caused by shoot up system/egr problem,other guy telling me it is problem with elect. short/wire harness problem. I don't know anything about this, could all codes come from one thing? Any help would be great,thanks

All those codes do point to one thing. FICM. When a FICM dies, it can cause all types of codes to be thrown. For instance, when my FICM died, I had a few codes thrown that do not even relate to a Diesel engine.
I suggest FICMrepair.com for a repair service. Top notch guy, fast turn-around and great pricing. I have yet to see anyone say something bad about their experience with Ed, all posts have been positive.

NYC-F350 just nailed it down for ya...


Q: HOW DO I TEST FICM VOLTAGE?


A:***FICM voltage tests should be performed with the engine oil COLD (ie, close to ambient air temperature). This will force the FICM into it's inductive heating strategy, which will give you a worse case scenario/voltage reading. If the engine has been run (within 5-6 hours of this test), then the warm engine oil may not give you an accurate FICM voltage.

On all 2003-2007 Ford 6.0L Power Stroke diesel engines you will find the FICM bolted to the drivers side valve cover...you may need to unbolt the coolant reservoir from the 'cowl' so that you can get your arms/hands back there to work on the FICM.You don't need to drain the coolant...just unbolt the bracket that hold the coolant reservoir, and gently move it as far out of your way as possible. Be careful, as there is a plastic coolant connector that can be cracked if the coolant jug is handled forcefully.

On the top of the FICM, you will see a diamond/oval shaped metal plate...remove the two screws from that plate (Torx#20).

under that plate you will either see 7 "lugs"...or 4 "lugs" (depending on the year of the truck)...

if you have a "7 lug FICM"...you want to put one lead from your multimeter onto the upper left "lug"...and the other multimeter probe to ground (bare spot on the cylinder head, alternator bracket, negative battery terminal, etc).If you have a "4 lug FICM"...you will want to check the lug on the right (closest to the drivers side fender).

be careful NOT to lean the probe on the FICM lug...over onto the aluminum case...you might let the smoke out, LOL...

Have someone turn the key to the 'on' position (don't crank it yet)...and see what your FICM voltage is. It should be >46volts.

Next have someone crank the engine...and see what the FICM voltage is while cranking...again..should be >46volts.

Go ahead and start the engine...and see what the voltage is while idling.

If the FICM voltage drops below 46 volts...then it is "bad"...
