Ford 6.0L Power Stroke Diesel :: 2004 F350 - Low FICM Voltage Under Acceleration?
Feb 25, 2017
Pulled the trigger today and bought a 2004 F350 DRW King Ranch with 200000 miles. Using Forscan Lite on my iPhone, KOEO FICM voltage was right at 48. During start it went up a bit. While out for my highway road test for EOT/ECT differential (never went above 10 degrees).
I noticed that the FICM voltage would drop to the bottom of the Forscan scale (40 volts) when I was accelerating and then go back to 47.5 when I reached my cruising speed. Is this normal?
Batteries are brand new from Ford. I didn't notice the battery voltage. Truck seems to run great to me, but this is my first 6.0. I also got DTC's for all 8 injectors saying Injector Circuit Low.

I replaced injector couple weeks ago. I hooked up to livelink thru sct because it was throwing a low voltage for ficm code. It is staying at 48 volts tho. I don't see any voltage from my glow plug relay, and I have a low voltage for my egr valve. Is it just bad luck that everything broke at once or is there a fuse or a connector that I forgot to plug in.

I'm afraid my FICM is on its way out. I'm getting voltages dropping to 46.5V about once a minute. Never goes below that. Then it'll bounce up to around 48.5. It gets low when I have to rev up and always coincides with the main voltage dropping to around 12.9V.
Now for my battery condition. They are about a year old. I think I have one with a bad cell. They'll drop into the low 11V range while cranking after glow plug light goes off. While driving, the main voltage never gets below 13.1 except for very short periods ... which coincide with the 46.5V output on the FICM. Gonna have them tested separately at advanced auto and see on has a bad cell.
So, is my FICM starting to go? Second question. What do I tell the folks at Advanced Auto about replacing both an not just one? I suspect they'll want to argue about it with me.

So I am getting low FICM volts at cold start. The FICM will start at 46v and eventually drop below to 42v, but when I start to drive the truck the FICM volts go back up to 47.5, and my battery voltage goes back up to 13.8 to 14.1.
I am pretty sure my alternator is doing its job.
I left my truck sit for 2 or 3 weeks with out starting her or putting a battery tender on it, this was about two weeks ago. I have not had this problem before. Sounds to me like the batteries need a charge.
My batteries back up to full charge. I plan on letting the truck sit over night with a charger hooked to it.

At idle it stays at 48.5v-47.5v But as I pick up speed it continually drops. At 70mph it gets as low as 29v. But will go back up slowly as I let off the throttle.

I've noticed on mornings when it's around freezing or colder my FICM voltage drops down to around 40. after about a minute it creeps up until it's in normal range, about 48 volts or better. This only seems to last about a minute before it's in normal range. No check engine lights though.

Well, coming home from work Friday and my truck turned on the check engine light. I did not notice any loss of power or other driveability issues. When I got home I pulled the DTC's. I got P0264, P0273, P0276, P0279, P0611, and U0306. The first four being low voltages. The Second FICM. And the last cylinder 6 misfire.
I sent a message to Ed at FICM Repair asking if there was anything to check before I pulled the beast. He said no it needed service no matter what at this point. BUT, I needed to test batteries and alternator. So I spent some time today pulling off my FICM.
I went ahead and pulled the EBP sensor and tube off from the exhaust manifold. The manifold end was very clean. BUT, the sensor end had a noticeable restriction. I would guess a 40% restriction. I cleaned the tube and the sensor and put it back on.
Next I moved to the EGR. I pulled it off and it was dirty but not what I would call restricted. The valve moved freely. I cleaned it anyway and blew out the manifold before I reinstalled it.
I have the batteries on a charger right now. Once they each charge for 12 hours each I will let them sit a day or two before I load test them. They are about four years old, AC Delco 60 month 875CCA batteries. I have had problems the last 6-8 months with staring the truck. If she sits for more than 3-4 weeks without being run she turns over slow and won't start. So I have had to jump start her a few times. And before you ask I have done a parasitic check and only have .05amp draw. So maybe the alternator is getting weak.
On that note I pulled the alternator and will get it bench tested this week. While I was there I noticed the top grooved and smooth idler pullies were a little "wobbly" so I yanked them too and will replace. Might as well do the belt while I'm at it. Boy this is going to get expensive real fast.
So, I decided to go ahead and replace the bottom coolant recovery hose and the long hose/pipe heater hose too. Boy it never ends. Oh well. I would rather do it now while I have stuff pulled off and it is easier to get to. Ordered those parts from RockAuto to the tune of 219 dollars. OUCH!!!
I accidentally broke my new engine oil dipstick while I was trying to get to the FICM!!!! CRAP!!!! More money. So......... Is there anything else I might want to look at while I am there?
The truck is 2006 F250 6.0 PSD CC SB 4x4 mid optioned XLT with 108,000+ miles. I have a 4" turbo back exhaust, AFE Cold Air Intake, Blue Spring, Hypertec Power Program 3 on the lowest setting, and an after market intake elbow at the intake manifold and an engine oil bypass filter. Turbo was pulled and de-coked about 18,000 miles back. Otherwise no issues. The 90,000 mile service was done about 10,000 miles ago. She gets regular services.
How about methanol injection? Will that keep the intake clean from the EGR sludge? I'm not thinking about added power, just keeping things cleaner? I plan to do the Atlas 40 when the FICM gets repaired.

I have a 2006 F350 with around 208k mikes, automatic with a no start, 0 No FICM Sync.
The CMP and CKP has "no / 0" for synchronization and a "NO" synchronization from the FICM. Should this be "yes / 1" when trying to start?
The camshaft position sensor status indicated "yes fault".
FICM is at 48V,
DTC currently on
P2614 camshaft position signal output/open circuit - CMP
Glow plug circuit cylinder 2, 4, 5, 6 (these have been on for 12months and 1,000 miles and never had an issue starting)
B1352 - left front temperature damper motor
B1360 - left rear temperature damper motor
U1900 - CAN - communication BUS fault
I am running all OEM filters

I just bought a 2007 F350 6.0 two days ago, so I was giving the truck a good wash today using a electric pressure washer. The engine bay was pretty dirty so I decided to take some soap and a brush to it. After cleaning it I let it sit for a while in the sun to dry. (engine was stone cold). After it had completely dried out I go in and it cranked right up. I let it idle for a good minute-minute and a half put it in drive and pulled away slowly, right when I touched the accelerator it started running rough, so I popped it into neutral and let it idle for a sec but it was still running really rough so I cut it off not wanting to damage anything worse.
I let it sit and tried to start it again, it just turned over and over. I checked the oil level it was good. So I pushed it back into my driveway to figure it out. I took ICP connector out and tried to start it, just turned over and over. took fuel filter out it was just replaced 2K miles ago it looked a little dirty but not super bad. I put that back in. took icp out again and tried to start it and it started but ran super rough and was dumping black smoke out.
I checked back all ficm connectors and they were all connected. I haven't checked the voltage on that yet, but plan to do that tomorrow. the previous owner had the ficm go bag about a year ago and he sent it off to ficmrepair.com and they fixed it for him. also he had the stand pipes and dumby plugs done as well as the stc on hpop. im kinda at a loss on where to go now other than to check voltage on ficm.

2005 f350 6.0. I was driving my truck and it seemed like someone had shut the fuel off to truck ! i had it towed to the house and was doing research and watch a video on checking the ficm with a volt meter..when i touch the positive post from meter the ficm started smoking and sizzzling...but back tothe truck when i try to start it i have no pre warm up sounds coming from the truck and the truck just turns over strong ..no start...i was going to replace the ficm but didnt want to spend the money to fry another if that is not my problem..also the # 5 fuse under the hood keeps blowing.

I have a 2006 F-350 4x4 CC LB. I recently had my check engine light come on coincidentally on my way to the auto parts store. Asked them to plug in the scanner and read the code. It had around 20! This truck has 40000 miles on it. All of the codes were dealing with injector voltage being low. All eight cylinders. So I'm thinking ficm is going out. I replaced the batteries shortly after this. I driven it a time or two after this and it started cutting in an out going down the road. Seemed down a few cylinders for a few seconds and pouring black smoke from the tailpipe of a stick truck. Made it home after it did this there times. Stated it up to move it a few days ago. Some white smoke that clears quickly and ran rough for a few, pulled it in gear surged forward and died. I cleaned the EGR valve and re o ringed it. Tested the drivers side pin on the FICM and have 47-48 volts with key on and cranking.

My truck is a 2005 f350 6.0, all stock except for an egr delete and 4 inch cat back exhaust. I recently did an oil cooler replacement and egr delete, resealed all 8 injectors, and fixed some wire chaffing at the FICM. it's running great with the exception of idling. It seems like it's idling low but the gauge stays at 750. If I hit the high idle switch, it does fine. Red lights are stressful because it shakes and sounds like it's going to die but never does. I'm posting screenshots of my Torque pro.
I have a SC2 as well but I honestly like Torque better so that's what I use most. I know my ICP is low, but 8 don't know why. No oil in the connector, and no change when I unplug it. The ICP sensor may be a month old with 1000 miles on it. This was taken at a hot startup, sitting in park. When i say hot, I mean I had driven about 60 miles. This is sitting still in drive. ICP voltage finally climbs over 1.0 when i get going about 15mph at around 1250 rpm. The second pic the ICPV is actually higher than normal. It usually stays at .8 until I give it gas.

I bought my f 350 new from the dealer and have had many of the problems associated with this truck. Now I have a severe shudder while under acceleration when i either let off the gas or increase speed the shudder goes away. My dealer thinks it is injectors but I have little faith. Shudder seems to be rpm consistent and seems to be in the front end. oh yea it idles great and runs great except at that specific range.

Got in my 06 F350 dually 2 weeks ago and after start up had no instrument indications. Truck ran great, flat line on panel. Tow haul light out also. Drove it for appx 5 miles, shazam all start working and then they cycled on and off for a while. After 10 miles, came on solid. Happened again at a later date.
Here's what I discovered. I noticed high voltage on my Scangage II. As in 16.2VDC. Monitored it coming back from a hunt. 14.9-15.5VDC. Would blank out only after hitting 16.2VDC. I'm suspecting there might be a cutout to protect the instrument cluster from damage.
Installed a new alternator on Friday the 13th. Drove home this weekend, 4 hours and no problems. Hopefully didn't boil off the batteries. Now 13.5-13.9VDC ... Just something to be aware of!!

I have a 04 f350 6.0 with about 195xxx miles on it. The other day my truck started acting up. It starts and idles without a problem and drives fine till the engine gets to operating temp once there I cannot accelerate quickly like getting onto the highway to get up to speed it just the motor just goes quiet and won't accelerate. It usually does this a little after 2000 rpm. I can let off the throttle and slowly get to speed as long as I don't go past 2000 rpm. No check engine light was not on scanned it and got p0611 for the ficm. I tested the ficm and it read 48v with key on. While truck was running I got 46.xx v then Started to climb to almost 48v. The truck was warm but not at operating temp where the problems starts(didn't have time to let it warm up all the way) could these symptoms be the ficm still? What else should I test?

Just asking where about's the ficm relay would be under the hood of my '04 6 liter, I have 3 boxes to chose from.

2004 6.0 Truck has been slow to start and sometimes took a few tries to get it to fire up. On monday the Truck would not start. The FICM was not getting sync. I figured it could be a bad connection to the FICM. I pulled the FICM, cleaned the contacts and reconnected it. The truck fired up. It ran all day Tuesday without incident but wednesday morning it would again not start. Again what was missing was FICM sync. This time disconnecting and plugging back in the FICM did not fix the problem. I have spent the last two days troubleshooting and am out of things to try.
The problem as it stands right now
The truck will crank but not start. Scanner says it has oil pressure, a steady 48v (FICM has new power supply). The IPR sits around 50% when cranking at 1200psi. However, the FICM will not get sync. I have worked my way down and tested both the Cam and Crank sensors from the PCM. The Crank sensor has a resistance of 360 ohms and produces a AC voltage of 500mV when cranking. The camshaft sensor produces 100mV AC when cranking (camshaft sensor was replaced as the original produced AC voltage seemed low 20mV, new sensor produces 100mV). I have tested the camshaft sensor at the sensor and at the PCM connector. This has lead me to believe both the cam and crank sensors are ok and their signals are being probably transmitted to the PCM.
I have tried to check the inputs to the FICM to confirm the signals are getting there. I was unable to find a good pin out diagram for the 2004 FICM but what I found told me the crankshaft was pin 5 and the camshaft was pin 10. When cranking, pin 5 (crankshaft) did not produce a signal and pin 10 (camshaft) had a 200mV DC signal. Despite searching I have been unable to find what the input signals to the FICM should be.
Right now I suspect bad wiring between the PCM and the FICM, or a bad PCM. This is based on having good signals to the PCM, but (what I think may be) a lack of crankshaft pos. sensor signal to the FICM. I am specifically looking for what the crank/camshaft pos. sensor signal at the FICM should be, as well as confirmation/disconfirmation on the diagnosis of bad PCM or PCM-to-FICM wiring

Late 04 6 liter, I'm in the process of putting my engine back together after doing studs. head gaskets ..etc. Its been awhile since I took it apart, and my memory isn't quiet what it use to be. There's a small stud on the ficm bracket, nearest the firewall and I honestly don't know what mounts to it. Ground wire maybe?

I have a 2006 6.0l f350 crew cab that blows air hard every time I accelerate. Sounds like you're going 100mph with the hood unlatched. It blows real hard for a minute and goes away if I accelerate through it or let off.

I recently purchased a 2011 F350 chassis cab with no bed installed. Have a few questions regarding the exhaust system. When I inspected and drove it noticed some black smoke when under hard acceleration, nothing major though. Other that that the truck drove great. Have not got the truck home yet, a friend is going to pick it up and deliver it in a few days. Based on the visible smoke I was suspicious of the exhaust system but I have no knowledge of what the system is suppose to look like. My experience with diesels and for that matter gas engines is mostly from the days of mechanical fuel injected diesels (70's era farm tractors mostly) and carberated gas engines.
My friend stopped by a local Ford dealer and crawled around under a new 2015 Chassis cab to look and compare to this 2011. It appears that the SCR and DPF are not installed on this truck. Where they would normally be is a section of pipe with a section about 2 feet long that is 6 or 8 inches in diameter. Looking at some threads on this site I'm guessing this is a muffler that has been added since the truck is not loud. There is no DEF tank and all the wiring for sensors that would be attached to the exhaust system appear to be tied off to the frame and not connected to anything. The dealer didn't know the history beyond he purchased it on an auto auction and he installed a new rear end in it. Car Fax shows nothing of concern.
My question is should I now be concerned since have determined much of the exhaust system has been removed? I've read some threads and it appears that the only way this can be done and have the engine run well without any codes etc is if the removal is done with some sort of tune. Is there any way to determine who has done the tune? Will it be an issue when take to a Ford dealer for service?
I know if wanted to put the system back to stock would be large dollars, as long as the system runs well and is reliable I will be happy. The anticipated use of the truck will be to pull gooseneck trailer and will probably not see more than 1000 miles a year towing and 5 to 10k total in a year. I drive with a very light foot seldom ever pressing any vehicle to its limits. If still have the truck in 10 years when retire or at least cut back on my work then it may see more miles.
