Ford 6.0L Power Stroke Diesel :: Code P0262 - Cylinder 1 Injector Circuit High
Mar 6, 2015
Have a 2004 F350 which had problems starting cold and once started had bad throttle response until warm. It also had a shudder at cruising speed when going up a slight incline, would shudder until turbo kicked in.
Pulled codes which related to FICM and codes for all 8 injectors. 7 injector codes were circuit low, cylinder 1 high. Tested FICM voltage and sent FICM out for repair.
Installed rebuilt FICM, cleared codes, and hard start went away, but cruising shudder is still present.
Only existing code is P0262 for cylinder 1 injector circuit high. I'm assuming that cylinder 1 injector is bad -- are there any tests to confirm before I take it apart to replace it?

I have for a week suspected my batteries were getting weak. just slower cranking is all. I took my truck in to have a viper security system installed and while he was doing his work he killed the batteries. I saw him hook up a battery charger and started the truck. He pulled it around to me and explained how the system worked and off i went. 5 miles down the road, on the thruway, I notice a miss and I'm down on power. FICM looked ok, 48V and it was charging, 13.8 I thought I would bring it to my shop and load test the batteries. On my way here, the check engine light comes on. At the shop, load tested them and they were weak. Installed 2 brand new batteries, started it up, no difference. Hooked up the scanner and pulled a code P2077 (cylinder 6 injector circuit high) Now what? I'm not sure where to go from here. I'm guessing either the FICM went bad or the #6 injector?

Engine light came on yesterday and started missing on take offs. Giving code p2285 Injector Control Pressure Sensor Circuit Low. I've done the research and understand the problem. It's the weekend and shops closed until Monday. Is it safe to drive in the mean time? Is there any risk of doing damage? What's the risk of it quitting or failing start in the short term, today?

I've got a 1271 code and I can't seem to make it go away. Code definition is "High side to Low side open Cyl 1". The truck runs fine, no rough idle, no excessive smoke of any color, just the damn CEL light stays on. I check the UVCH and all the injectors ohm in at 2.7 ohms. I've already done the updated clips under the covers. I run all the buzz tests and KOEO/ KOER tests and all appears OK. My AE won't do a Cyl contribution test. All the injector data shows all 0.00. I know its not that perfect. "high to low open", does that mean I've lost a ground? If so where?

I'm excited to be a Powerstroke owner again! I had a 2000 with the 7.3L and since bought and now sold a Chevy 1500. Last week I bought a new 2015 6.7L. I am MORE than impressed and love the truck. Today I brought it to get the windows tinted. I have not had one issue with the truck since I have had it. When they finished with the windows, my check engine light was on. The shop I had it done it EXTREMELY reputable. They brought out their snap on scanner and pulled the code. p0073 for the ambient air temp sensor circuit high. Is this a coincidence that this came on after they got done, or could something they did while tinting the windows tripped this?
As I drove off down the road after determining I wasn't going to hurt the truck, the air temp sensor went from showing -40 to the actual temperature. What would cause this? I deleted the code when I got home with my actron, and the MIL has stayed off since, however, it shows P0073 Permanent ...

Yesterday driving to work felt the engine missing, on the way home got a CEL pulled the code when I got home it was P0302, so I started with the easy and put a new coil pack, same issue, so I prayed and pulled the plug (it didn't break). Put a new plug and a second new coil pack (just to be sure, and yes I keep extras dang 5.4). cleared codes and started it this time got P0202 Ford - Injector Circuit Malfunction Cylinder 2, so I checked Ohms on #2 and it was 12.6, #1, 3, 5,6 all have 13 Ohms, didn't check #4, 7, or 8 because my big hands and the probes on my multi meter. Checked the wires on all of them and have 12 volts with key on, not running. I read another check to put blk in pin and red on pos batt terminal, and that it was supposed to go 12 to 0 off and on with engine running, All of mine went up to 14 volts and stayed no switching. Is there something I am missing to check before replacing the injector on #2?

I bought my truck 2 month ago. I use it for commuting, only short trips now ( 10 min ). After about 2 weeks the Check Engine light came on. The truck is running fine, no problems I believe, starts easy. After another 2 weeks, the CEL disappeared. Another week, and the CEL came back on and it`s there since. I have a code reader, these are the codes and meanings according the manual:
P0299 - Turbocharger "A" underboost condition
P2286 - Injector control pressure sensor circuit high
P2287 - Injector control pressure sensor circuit intermittent
P0299 Pending - same as first but with "pending" status
This is my first diesel and my first turbo charged engine. Is this a common problem? How serious? It`s a bit strange that the error came up before but disappeared. Can that happen just because of the short trips I`m making? I`m planning a long trip soon with towing my trailer, so I want to make sure the truck will not break down during the ride.

Just got back from the beach yesterday. On the way back I noticed the check engine light on and read the codes. It listed 4 codes, P0671,P0672, P0677 and P0678. From what I can find, Cylinder 1, 2, 7 and 8 have the glow plug circuit open. Truck ran fine and didn't miss a beat. Ambient temp was around 80 when we started up the truck so I guess diesel plugs are not to crucial for that temp. I did notice when driving back the Vbatt would jump from 12.2v at1854 RPM (34 MPH) and 13.8v at 1652 (57 MPH).
Would bad batteries or low batteries cause this type of problem? This may be wishful thinking on my part. I have tested the batts with a DMM and they are at 12.3v. I took them out and charged them but they always go down to 12.3v. FMP is 47.5v to 48.5v. It seems suspect that all four glow plugs would be bad so I assume it could be the harness. What are some ways I can test to verify where the problems come from.First thing I would do is get two new batteries as these are still under warranty.

P0073 Ambient air temperature sensor circuit high. Preliminary inspection, right outside mirror badly damaged/broken. Guess where the sensor is?

Getting DTC Code P1271 - #1 Injector High -> Low Side Open.
The code tends to show up more during cold weather start up. Using AE-AutoEngenuity KOEO - Buzz Test returns the P1271 error
Troubleshooting performed:
- 42-Pin Connector @ Driver Side Valve Cover
- 9-pin VCH on Passenger side
- IDM Module under driver side wheel well
- All of these are testing within the 2.8 - 3.2 Ohm range
- (Used the GB Reman. Tech Bulletin 103) - TB 103: 1994-03 Ford 7.3L IDM Replacement & Diagnostics)
I was going to replace the solenoid, however, with the above readings I'm not convinced it's the solenoid. Before I tear into the valve covers I was looking for some add'l thoughts from the forum. Could it be the IDM ?....
Any add'l checks to perform using AE, or the IDM, other than replacing IDM.

Been working on a 2005 6.0 with 218kish miles on it. When I got the truck it had a contribution 2 code stored, no check engine light, just could see the code on the code reader.
Truck idled like crap, lacked power, so I replaced the injector. Truck improved but still had a miss, this time it had a stored code of injector 6.
Ordered another injector, got it installed today. Fired the truck up, ran perfectly, drove it around, absolutely 0 issues ran like a dream. Parked it for a few minutes before starting it again to wash it. Rough idle, not horrible, not noticeable. Cylinder 6 contribution code stored again, no check engine light.
So I drove it, I drove the hell out of it for about 15 minutes with the AC at full blast, WOT, etc etc. By the time I was done, truck was back to running smoothly.
Just walked outside after dinner to see if it would still perform well, or if it would idle poorly again, sure enough, 6 contribution, rough idle.
I just changed fuel filters with OEM, air filter is new. I just cleaned the EGR valve- although maybe it's not clean enough?? Oil change is tomorrow (had to wait for the filter to get shipped in).
I'm at a little bit of a loss on how to cure this miss, unless it's possibly an oil pressure issue from bad/old oil causing it?

2006 F350 6.0 throwing code P0480 and I'm having a hard time figuring anything out pertaining to my truck. Trying to figure out what exactly it is and how to fix it myself.

Over the past weekend I had to replace all of the egr gaskets and seals, due to it failing smog. I removed all of the harnesses over the motor, intake manifold, turbo, and oil filter housing. I also replaced the oil/oil filter and also the fuel filters. The truck ran great before I decided to replace all of the seals. When I went to start the truck, it would just crank and not fire. One thing I noticed was that my wait to start light only stays on for a few seconds, where before it would stay on for a while. After cranking on it for a while I got a code P2623 for the ICP circuit open. I have tried unplugging the ICP sensor to see if it would start, but it just cranks over. The truck sounds like it wants to fire, but wont. Should I pull the ipr and ICP sensor?

my excursion just started hard and had rough idle one morning then code P0270 - injector, FICM or wires between are the logical choices I think.
started with wires - all connections good at FICM and injectors (applied dielectric silicone) - checked all 4 wires from injector connector pins for resistance with omh meter from X-1 connector. no change
so next is FICM. couple years back sent to ed for repair. if I remember right it was power supply side only so the "brain" side might have gone? good news is could I get a loaner FICM off fellow 6.0 and installed (can't confirm condition of loaner - trucks been parked a while) same code same cylinder - no change.
I read somewhere possibly swapping two injectors (say 2 and 4?) and see if the code follows the injector or stays with the cylinder, further test for a bad FICM
Is that necessary? I would hate buy and replace the #4 injector just to put it back together to find no change then forking over 6 7 hundred more on a new FICM.

I just did a bunch of work on my 6.0. Here's a list- head gaskets, arp studs, new heads, 2 new injectors, updated stand pipes and dummy plugs, water pump, and all new injector o-rings. After messing around with a bent pushrod, cylinder 5 code and and replacing injectors the truck runs excellent. After driving it a bit I get a code "P2290 injector control pressure too low". The truck runs great with no low power, stalls, or hard start cold or hot. I do puff black smoke but that's because of the sct tuner on performance tune.

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.

In the last 300 miles, I have replaced all 8 injectors with rebuilt units. Shortly after assembly I had P0264, P0270 and P0272, so I replaced #2 and #4 injector. When I went to pull the oil rail, the two screws holding the top of the #4 injector were gone and the injector was in half. Easy to say, this was this issue with that one. I am assuming #2 had a coil issue.
After assembly, I am still getting P0272 with a rough idle while cold or hot. It does seem to lessen at higher RPMs.
FICM has less than 300 miles on it. Atlas 40, Ultra mods from ficmrepair.com.
Injector harness is new.
Using AE - Injector buzz test is ok. Power balance shows number #4 with slight issues. I will post screen shots tonight. ICP is always within a few points of desired. It builds in excess of 3,600 at WOT.
I have only driven 10 miles since the assembly.
1) Can air in the system contribute to this code? Should I continue to drive around and reevaluate?
2) Should I send the FICM back to Ed for review?
3) Any other thoughts?

2003, not deleted, everything was stock except for he put a Bully Dog on it with can tunes. Died on him was replaced ICP started up ran horrible was throwing different injector codes, IPR was at 84% at idle, plus had a lot of pressure on degas bottle.
Just finished studding, deleting, oil cooler, ICP, and injectors. She started up fairly easy, only to have the IPR still at 84%, ICP bouncing between 670s to 790s this just after start up from the work. Truck still runs horrible and still throwing #5 injector code also using AE and injector 5 wont Buzz. So, would be safe to say Injector harness and IPR sensor?

I have a code for iat sensor 1 circuit high. It's the only code I can pull. I replaced the sensor in the manifold and still no change. The truck revs up when started but kinda finds its idle rpm after a second and the idle fluctuates some when the truck is warmed up too. I have a snap on solus and all parameters seem to be good. Icp sensor is also new thinking it might be the cause. Other than that the truck runs perfect and doesn't miss a beat.

I have a po6a7 code boost gauge pegged at 40 code says vref circuit b out of range. What sensors run on circuit b and what could possibly be the problem my camshaft sensor is reading fault on scanner don't know if that has anything to do with it taking the truck to the dealer is not and option it's a 2011 6.7 with 75,000 miles....
