Hi I have trouble with my ford e-350 7.3 turbo diesel 2001 .I need some opinion my truck loss power sccaner say on koe test someting wrong with 4 fuel incj first bunch white emmision after that its die before i have some link on cenection pipe from engine to turbo.Overdrive button flashing. What kind scanner i can use to read code . Thanks Adam

 

What part of IL are you located? Maybe someone close by will come over and scan your codes.. The flashing OD light is either showing problems with your trans or maybe the sensor on top of the rear end is bad (VSS). Is your speedo acting up?

 

Welcome to FTE Adam.

What scanner did you use to find out about the injector issues, and exactly what did the scanner say? Was it a KOEO, or KOER test? Usually 4 dead injectors is accompanied by a P1316 code. Did the scanner say which 4 injectors were having problems? The common problem is the connector for the injector wires under the valve cover coming loose, so those 4 injectors quit working. I haven't worked on any E series, so I'm not familiar with how hard things are to reach under the hood.

If you look at the top of the motor, you will see a flat wiring harness that plugs in to the inboard side of each valve cover. Find that plug and tell us if you can reach in there and use an ohm meter to check the pins inside that plug. If you can reach it, we'll tell you how to test the wires with the meter to see which side is bad.

Which tube has the leak? Is it one of the aluminum tubes that has an oily sludge around it? If so, then that's not bad news. We can talk about that after we fix the major issue. As for a scanner, I use AutoEnginuity PC Scan Tool (USB)

 

Hi im located in bensenville my mechanic plug the sccaner and say 4th fuel incector is bad he recommended change all of them.Before i change speed sensor i got code for speed sensor also i ihave code for icp not as exepted so dealer say take off sensor and clean the pipe put some carbonated cleaner or put some wire inside thru hole where icp is located and this fix the trouble and also i had code for cmp sensor so dealer change this for free recall service and no code show up but still dies when hot some sugestion thank you adam

 

How many miles are on your truck? Do you always change the oil when it needs to be changed? I guess I read your earlier post wrong. If only the #4 injector is bad, and the engine has been taken care of, I'd just change the one injector. Have the mechanic do an injector buzz test and cylinder contribution test (or get per delta readings) before you spend any money on a full set of injectors. Just be aware that the "new and improved" gray CPS (CMP) Ford offers for the recall tends to show problems with the #3 & #8 cylinders. Don't let them sell you a bunch of parts to fix an issue caused by the new CMP.

Is there any way you can tell us what codes the mechanic pulled? Cleaning the tube and sensor is something you do to fix the EBP codes. The ICP does not have a pipe to clean, and if the ICP was causing your problem, you could simply unplug it to see if the truck runs better.

A bad injector, or even 4 injectors not running, will not cause the truck to die. One bad injector will cause the truck to run with a little miss. One bad injector solenoid, or 4 shorted out injectors will cause the truck to run really rough, but they keep running.

Was all the work done by Ford, or did you have an independent mechanic look at it too? I think it's time you start asking more questions to your mechanic about exactly what codes he found, what tests he's run, how he came to the conclusions he did, and would those issues explain all the problems you're having.

 

OK my truck have 126 k before code P0500,P0340,P1212 ok you wrigt icp dont have pipe have sensor other side fuel injector i think first change filter diesel fuel been very dirt i buyed this truck three months ago i have before 1995 e-350 powerstroke no any problem but i sold that truck now i have two truck one 126 and dies when hot and also second one is e-350 7.3 powerstroke and have some problem with exhaust presure control valve high P0478 and P0470 exhaust pressure circut fault on 1995 i think i get more mpg like on this two adam thanks

 

P0500 is a code for the VSS, which is the speed sensor located on top of the rear diff. This could be your flashing overdrive problem.

P0340 is the CPM code which should have been fixed when they changed it out.

P1212 ICP voltage not at expected level. Your mechanic should be able to read the ICP pressure and voltage with a good scanner to see if the sensor is working. If you have a rough idle and it doesn't seem to start well, you can try unplugging the ICP sensor which will cause the computer to assume default values of what the ICP should be reading.

 

Hello i change speed sensor is located on uppers side transmision p0340 dealer recall icp i clean the hole where icp located and no more codes show up but still dies when hot.Maybe is mufler problem.Now only sccaner say on controbution test 4TH injector is bad mechanic say to mee. thank you adam

 

How regular does it stall? Can you take the truck back to the mechanic and make it stall while it's on his scanner? Is your engine oil full? Have him watch the IPR % & ICP psi when it stalls.

Are you still getting white smoke just before it dies? Is it a lot or a little white smoke? If the bad injector is dumping too much fuel, you'll want to change it before it causes some damage.

 

HI thank you for respond yes like after betwen 2 to 5 milies drive truck dies white smoke is always after two minuts start running and then again dies after maybe miles .When is cold its ok. Where is located 4 th injector is hard to change.

 

So vehicle speed sensor is located in back wheel and transmision speed sensor is located on the transmison i change that sensor on transmision.

 

There are 2 sensors on the transmission. The TSS (turbine shaft speed) & OSS (output shaft speed), then you have the VSS (vehicle speed sensor) on the rear diff. The VSS is usually the one with the issue, especially with the code you have.

As for the injector, how comfortable are you poking around under the hood? No it's not very difficult to do, but it will take a little time. If you're not scared by the thought of doing this yourself, then we can help you get it done. You'll need to pull the aluminum IC tube, remove the valve cover, some drain the oil rails here and some don't. The important part comes later getting any oil out of the cylinder. Unplug and remove the wiring harness/gasket, unbolt the lower injector hold down bolt, remove the oil spout, slip the injector hold down plate up off the upper bolt (or remove the solenoid and just unbolt it) then pry the injector out.

Take a breaker bar and turn the motor by hand to evacuate the oil out of the cylinder, lube the injector o-rings, and install the injector (tap it into place) Unplug your CPS, or pull your IDM fuse, then remove the glow plug for that cylinder. Crank the engine a few times with the key (it won't start). This will remove the remaining oil from the cylinder. Replace the glow plug, install the harness/gasket, and put the valve cover and IC tube back on. While you're in there, check the torque on the rocker arm pedestal bolts. They should be at 20 lb-ft. Tighten your new injector, and check the others to 120 lb-in.

If that didn't make any sense, we'll switch to pictures & video which I find a lot easier to understand.

Thank you im start doing this i must adjust incjector or just install what is torgue rod pedestal bolt i have check all of or just 4th one

 

Maybe i change vss sensor can causing this effect

 

Check with Napa... P/N 530780.. $10.49 when I bought mine a couple of years ago... (had a flashing OD light along with an speedo problem..)
