I have this problem code P0405. At fist it come up with a turbo under boost. I have replaced the Turbo and egr valve and I still have the P0405. I did notice a oily residual in the port for the egr valve I see no deference in coolant. She idles good I just have no power when I put it in gear to move.
View 3 RepliesThis morning when attempting a cold start of my 05 6.0, it would not start was noticeably harder cranking. I had no CEL. I checked my scan Guage and the volts were 13.4 and fcm main power was 48.4. I checked and I had a p0405 code. What could be going on? I read that it can be a stuck or bad EGR valve? Could it be battery related?

View 14 RepliesI have a 06 f250 king ranch with 6.0 . A few days ago my scangauge showed a code P0405
I changed my egr and after it showed two codes : P0405 and P0404
It still has a hesitation and loss of power , although better than before the Change.
My son is joining the site as we try to diagnose his first diesel. We checked fuel flow, and the bubble test. We held the valve down in the oil filter and watched it fill up in about 10 seconds and see it register on the dash gauge.
My Scan Gauge say it pushes 180 RPM while cranking, but it only gets about 225 on the ICP sensor and the IPR instantly maxes out at 84. It has thrown a code P2623 for a stuck IPR valve.
I hear a hiccup in the crank, but I'll let y'all listen and tell me. Will post YouTube link of it.
What are the chances of it being just a hole in the IPR screen or bad valve? I'm afraid we have a HP leak and need to do the air test to find it. I've never done that test and barely hear (rock concerts), my son hears but doesn't know what to listen for.
The truck was running great besides a little black smoke on WOT and a little jerk while towing. No codes at all. I pulled the EGR valve and got it all cleaned up and reinstalled. I also had time to pull the MAP hose and clean it. I pulled the nipple out of the intake and cleaned it also. I didn't unplug the sensor, just cleaned the hose. Now I am getting an engine light, the MAP gauge reads 2.9, and my turbo gauge is at 22.4 at idle. The truck isn't running right. What should I try first? I don't see what I could have done wrong but this is a pain.
View 11 RepliesI got a little oily residue on my hood here. It looks like it might be a little wet near the coolant hose & throttle body area. I also have the H&S Intercooler pipe kit installed. Not sure how long this residue has been there, but it is still wet, so its not all hardened. Maybe it's just loose intercooler pipe bolts?
View 7 RepliesFrom what I understand it should be dry where the valve goes. I would call it moist not wet but fairly moist. The top groove had the most wetness, the middle groove was dry and the bottom was nearly dry. Where do I go from here - the video I watched said to scrape out and vacuum - not dry enough.

Long story short I am working on an engine that was already dismantled (down to the heads). I am trying to figure out why someone tore the engine down. Vehicle is a recovered theft and it was recovered with all parts.
I removed the exhaust manifolds from the heads to start cleaning them up and replacing the exhaust bolts (rust). When I removed the exhaust manifolds the front two cylinders on the right side (1 and 3) were oily wet. The back two cylinders were sooty and normal. The front cylinder (2) on the left side was not as bad but did have a oily film on top of the valve and valve stem. I do not see any indication of anti freeze or coolant.
I looked at the head gasket and could feel a oil film between layers on 1 and 3. No oil on 2 that I could detect. I'm thinking there was a head gasket problem but not totally convinced. The cylinders and pistons look good from the top and the cylinders still show the cross hatch honing. No ridge on the top of the cylinder either. The motor has 122k miles on it.
Other than head gasket would there be something in common that could feed oil to those cylinders? I have eliminated the turbo. There is no oily film on any intake runners. It could just be a blown head gasket but it is not obvious if it is.
Blown fuse causing a lack of power to the OBD port?
I just got my Kiwi2 BT OBD2 adapter and was hoping to start diagnosing my truck, but the adapter won't power on while connected to the truck.
I pulled and visually inspected fuse #12, I also verified power to the cigarette lighter plug and the accessory 12v power outlet.
The adapter powered up with no problem when I connected to a co-worker's Tacoma.
I have a 2006 F-250 6.0 diesel. The high side service port schrader valve is leaking. Currently there is a charge on the system but its low. I planned on evac-ing the system, replace the cores and refill until i came across this valve remove/replacement tool from MasterCool. The only problem i have is not knowing whether or not this tool fits the valve cores I have. I see already that the high side is quite a large core. I cant even find a core removal tool at local auto parts stores to fit. What size my valve cores are or if the following would fit both high and low sides?
View 3 RepliesI am doing heads studs and gaskets on the truck. I forgot to remove the stand pipe and started to lift the head off the truck with the engine jack. Well i bent the stand pipe and the port to the bock was a little loose. Tightened it back down and it seems ok. Could I have damaged anything by doing that? how is that all connected to the high pressure oil pump? I just want to make sure i didnt damage anything by doing that and since im already here I would rather make a fix instead of needed to tear down again.
View 5 RepliesI 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.
View 4 Replies6.0 diesel 83,000 miles. My CEL is always on and my Edge gauge says it's lower than expected Mass air flow. I've changed the filter, cleaned the MAF with special cleaner and then replaced with new. I've replaced the EGR valve.
If I clear the codes and run it I don't get a CEL until I turn it off. But the next time I start it, there it is again. My Edge reads 0.0-0.3 MAF while running but what that means. One end of my cleaner box is slightly warped but I can't feel any noticeable leakage.
Everything runs fine but I would like to regain the ability to have that idiot light available to tell me if I have a new problem.
I got a 2006 F250 6.0 that won't start. It turns over perfectly. What I've done so far was change oil and filter, along with fuel filters. All fuses and relays are fine. I payed for the scan gauge 2 and monitored FICM SYNC, FICM voltage, ICP, AND IPR. Every thing checks out besides ICP. The ICP is reading under 400. So I unplugged the ICP. Still no start.
I decided to spray some starter fluid in the intake and turn her over. Boom starts right up and runs fine. I even drove her around for about 20 min. I get home and shut off the truck. wait a few minutes and nothing dead again. So ICP is low but the truck runs fine after some initial support from starter fluid. What I need to do next? I don't want to have to take it into the shop for something stupid I could do myself.
Also the code its throwing at me is P0231 Fuel Pump Secondary Circuit
I have a 06 6.0 no start . I was at a light felt a slight shudder went to take off felt another shudder and it just died. Changed fuel filters, unplugged icp no start still. No code at first now throwing p2291. Fuel pressure is at 62 when cranking. Hooked up air to the icp port and only heard air coming out of both valve covers inlets. Ipr was at I believe 60 to 65% when cranking. Little back round 2 years ago I did the whole sinister diesel top end kit and put the updated parts in. New o rings on everything that took them, new egr valve, standpipes and dummy plugs. On the injectors all new o rings and crush washers. I believe that's everything.
View 11 RepliesI have a 2006 6.0 F350 that has started stalling intermittently. Truck starts right up after a few minutes and otherwise runs great. I'm getting trouble code p2617 (crankshaft position sensor). Reading on some of these forums it sounds like it could be a whole array of things causing this. Would this sensor be a logical place to start or what, if anything, should I look at before getting any parts?
View 2 RepliesReplace the tft but still the problem, someone cones the number part of tft sensor harness, and as replace , 2006 f350 4x4....
View 2 RepliesI have a 2006 F350. It started running rough and white smoke from the exhaust. I did an injector buzz test and found no codes. Cylinder contribution check showed cylinder one was not functioning. I replaced number one injector, cleaned injector cup installed new injector and copper washer. Engine runs the same. If it was a wiring harness issue should that have shown up in the buzz test?
View 8 Replies06 6.0 F250 throwing code P0677 #7 glow plug circuit module. I don't think one bad plug would cause a no start, however coupled with too much oil possibly? Swapped my oil about 500 miles ago, I put in 20qts accidentally, drained off about 3-4 qts eyeballed, truck fired up and ran fine no smoke nothing. Yesterday morning I was leaving work and moved my truck from parking space to behind the bay at my fire station, I turned the engine off.
Loaded up my gear and turned the engine to the aux position and someone was talking to me so inlet it sit for a while in the auxiliary position. Went to crank no start, turned the key off then back on and it fired. Fast forward after 7 different starts throughout the day, I'm at dinner with my son we go to leave engine will not start at all, rolls and rolls and rolls nothing. Towed her home and scratching my head. Over filled oil with a bad plug cause no start??
Egr delete, new oil cooler, cat and muffler delete, upgraded Y turbo pipe. Also have an SCII throwing codes p0677 and p0401 egr code....
So I've been chasing a problem in my 07 6.0 for about 6 months now I had just changed the oil cooler and a week later was driving home and she quit a mile from my house I have since then changed the cmp sensor the alternator 3 injectors all the o-rings in the nipples of my oil rail both down tubes in the oil rail and the IPR valve most resently and last night I hooked it up to me auto engenuity scanner and the IPR valve is still not closing it stay at 14.84% the whole time I'm cranking. The only code I'm running is cmp sensor low a cuircut or something like that I can't remember the number.
