I get video for you in couple hours.

I do on passenger side

 

Here video with ohm meter.

#4 is dead it show 1. never change anything. You see that I switch 3/4 # to test ohm meter.

Found 2 codes.

1 is for ICP it say out of high range. I look at connector there oil in.

1 is p1293 for injector.

We tried buzz test only heard 2 weak. We tried on other F350 with 97K miles heard 8 buzz louder.

 

Did try plug block heat it start but horrible.

Got new codes again

P1280
P1293
P1284

Can't rev anymore or it blow smoke badly.

I look at ICP connector it been cover in oil.

 

Check the wiring for the ICP. Usually we see the P1280 when the truck has been started with the ICP unplugged or if the wires are chaffed. Also try starting with the ICP unplugged if you haven't already.

Is your new scanner the AE? Have you tried to monitor any live data while cranking or when running?

 

With the miles it has on it, I would say a lot of your issues are the injectors, and the o-rings. A couple weak injectors, I would replace all of them should you go that route. How warm is it where you're at? I can see the GP's aren't working right, but if it's warm, it really shouldn't matter that much. Has anyone mentioned fuel pressure?

 

Yes have AE scanner. Wasn't happy how they display live data you need select which to look. Oh well it work great what name I should look at ?

Today it was 47oF it start ok but misfire for couple seconds then warm. In Michigan.


Found new issues. It interested I have ask friends they have no idea.

it blow TONS blue smoke without load when you rev.

no smoke when it have load and rev. But rev seem slow but icp were unplug.

 

I probably won't get the names exactly right, but look down the list for something that sounds similar and just select one item for each of the 9 boxes. Leaving a few boxes blank won't hurt anything.

ICP psi ---> you're watching for a minimum of 500 psi to start. Make not of where it idles cold and where it idles warm. (around 700 cold and 500 warm)

ICP duty % ---> while cranking it should climb until the truck starts. Make note of what % it starts at and where it idles cold and where it idles warm.

battery voltage in volts --> how low does it drop while cranking, how long does it stay around 12 v after it starts (glow plug on time) and what voltage does it show when running.

Injector pulse width ms --> don't remember the numbers off hand but just watch and write them down

RPM

Engine oil temp --> should be near ambient cold and increase as engine warms up

Intake air temp -->near ambient

and anything else that sounds interesting. There is also a record feature where you can record the live AE data and share it with us as a graph or in an excel format. Once the engine warms up (EOT above 160 or so) you should be able to run a cylinder contribution test or watch your rotational velocity numbers (or change in rotational velocity) It will have an option for each cylinder so fill the first 8 screens with each cylinder and the last one with engine oil temp for future comparisons. That might give you some clues. Also the KOEO (key on engine off) buzz test is something you should try on a cold engine. You'll hear all 8 injectors buzz at the same time, then each injector 1 - 8 will buzz individually. Any weak sounding injectors might be a sign of a problem, especially if they get louder if you test them when hot or run multiple buzz tests. If you've got any hearing issues, you'll obviously need someone to help with this test. The test can also cause some codes to be tripped which might give us a clue.

You seem to be talented with the video, so if you want you can video the live data so we can watch.

 

Yes I will try that again in soon more like hour.

I tried cylinder contribution test but it keep say Failed due ICP sensor

<table id="codetable"><tbody><tr><td>P1280</td> <td> ICP circuit out of range low</td> <td> Open/grounded circuit, biased sensor, PCM</td></tr></tbody></table>




truck already drove on highway 3 hours ago so I am sure oil and engine still hot. But Temp drop 45oF

 

That sounds like the PCM isn't recognizing the ICP at all then. Are there any shorts, chaffed areas, burnt or brittle insulation on the ICP wiring?

If you're getting a P1280 code then there's a good chance the ICP psi you see while monitoring data won't be accurate since it will be from a pre-programmed table in the PCM.

 

Only I knew that oil hydraulic hose blew up before and it had brand new hose. You could see all harness and engine area cover in oil.

ICP sensor I look old original and you pull connector off you could see oil inside.

 

Found it have turbine speed.

Interested drive it will spin between 133 to higher that I missed but notice it was 2000 rpm around

When I try in neutral No load it wouldn't spin MAX 300 and see blue smoke pour at 2K rpm.


ICP psi stay 724.03 when drive around highest I see but I think I missed like 1203 psi at 2K rpm. I think I could make mistake it was hard to look while drive test.

ICP duty % been 14.45 but does go up little when rev.

battery voltage since glow plugs are dead so it 12.08 and Crank lowest I see 11.07 then charge it average 14.2-14.4

Eng oil temp cold 104oF and drive around city 3 miles it 145oF

Intake air temp 62

 

It's sounding more and more like a bad ICP sensor or bad wiring to the sensor. Your ICP numbers should move around a lot more than that. Rev the motor 500 rpms and ICP should jump several hundred psi. Driving around I would expect to see over 1,000 psi most of the time you're touching the accelerator with top numbers if you punch it reaching above 2500 psi.

If your computer is running in default mode because it's ignoring the ICP sensor, that could explain why the truck doesn't run right or the smoke shows up. A simple test would be take a short test drive going through some different types of acceleration. Remember you can use the record function and look at the data later so you don't wreck. Then unplug the ICP sensor and repeat the identical test drive and compare the results. If ICP readings are identical, you've at least found one problem.

Since the truck blew an HPOP line, that's another good reason to check the ICP wiring.

 

Went got other ICP sensor for FREE It came from 1998 Int truck.

Not work. I tried use brake cleaner and hobby dryer blower to dry connector.


Keep get P1280 when try Koer test and try cylinders test it keep get abort P1284


Well I decided check ICP pressure on AE if I drive gently it stay under 1300 psi. Blue smoke start when psi were 1600 or higher. Highest I see 2,500 psi when I stay in 1 gear and rev 2500 rpm with TONS of blue smoke.


Sound bad injector o-rings? They leak when too much ICP push oil?


No more codes for injectors anymore so I don't think it bad injectors now. Only I still see ICP P1280 that keep engine light ON and try do engine running test it will come P1284.

 

They leak all the time if they're bad, they just leak more the higher the pressure goes.

What about the wiring to the ICP?
