I have the same truck as the OP with pretty much the same symptoms. Service light, low power, stalls.

I think that you've pretty much provided most of the answers I needed already.

I've tested the ohms at the under valve cover connections and have found them out of range.
I've already sprung for new Ford gaskets, wire harnesses, Motorcraft glow plugs, along with o rings to do the crankcase vent mod.
I think I have my bases covered, thanks to you. If I have any troubles, I'll start a new thread. Thank you.

I have not posted here for a few years, but still my go-to for information -- thank you for the excellent details, particularly at the beginning of this thread, where I landed when I pulled my truck out of work this evening & light popped on, started stuttering & losing power & I worried I'd lost an injector or something. I will confer with my diesel guy tomorrow (NOT a dealer, a very very gifted neighbour; darn job keeps me too buried & exhausted to take things apart in the yard much anymore), but I am grateful to this thread for giving me hope that maybe it doesn't have to be a $$$$$ problem.

02 F250 300k miles CEL w/ p1316, 0733
 

First of all, wanted to say thanks to all of the posters on this thread, helped me out immensely.

Truck had been doing just fine, just rolled past 300k, and then I go to crank it up last Friday morning and the CEL comes on. Running a little rough at idle but not really crazy, didn't feel like a whole bank was gone. It's my daily driver so I headed to work. CEL went away once during the drive and then came back on. We have a code puller at work, so I pulled the codes and found p1316 and p0733. Did some research that night, found this thread and the videos to be extremely helpful.

Figured I'd pull the valve covers and see if the wiring harness was loose and do the .50 cent mod. Turns out the exterior wires going to the valve cover connector on the passenger side were corroded, all the shielding on the last inch before the wire meets the connector was flaked off. ohm'd the connector and had a couple bad readings, did the same thing on the driver side and readings were worse. Pulled the valve covers and both connectors were coming loose, pushed them back into the connectors and everything read good.



Start to unplug the inner connecter and the tab breaks off on the passenger side. Decided to just swap the entire gasket and harness on both sides, b/c the gasket kit from Dorman came with a new connector. Spliced the new connector in on the passenger side, closed everything up, CEL went away, so we took it for a test drive. Wasn't able to build boost, so we started digging around for loose connections or something we forget to connect, turned out we broke the MAP sensor when we were pulling the valve cover, on the passenger side. Took another trip to the parts store, swapped out the MAP sensor and test drive was good. Will post a picture of the bad passenger side connector when I get home.

Thanks again to everyone on the thread, it's been really helpful so far.

Now it's on to replacing a u-joint tonight...

Hey Cowboy
That's pretty good.............. Post includes I had this problem, did some research and found this thread which pretty much covered my problem, found one cause then another, created another, here's how I fixed them and thanks to all.

Nice job :-drink

I don't quite know how to connect my post to this thread. I hope this works!!!
My truck: 2001 F250 w/7.3 automatic 4WD

This is an old post, but they are my symptoms exactly except mine just started two days ago. The SES light came on and the truck sputtered a little on my way home and then shut off twice while backing into the drive--my normal routine. I drove it again today -- 10 miles into town, job site, errands, and back home with minimum 12 start/stop/starts. It ran great, no trouble starting, but the light stayed on all day.

I've just done the ohm tests and here are my numbers.
G G I I -- I I G G
passenger side 0.1 9.4 3.7 3.9 3.7 3.8 0.3 0.2
driver side 0.2 0.3 3.3 3.2 3.5 3.4 0.3 46.4

As the I to C Ohm readings are within limits (mentioned by Chris) the shuttering and cutting out are curious to me, so that is question #1--???
And then, are the "out of wack" glow plug Ohm readings what could be causing the SES light to come on?

It won't let me format the numbers into the columns where they make sense.

Glow plug numbers are
0.1, 9.4, 0.3, 0.2
0.2, 0.3, 0.3, 46.4

I to C numbers are within limits

Any suggestions would be appreciated--both on the truck and how to properly post on a particular thread!!

This was my problem when I had similar symptoms. Not saying that it’s your problem.
ICP sensor

I bought one from Amazon for a good price. I don’t put a lot of miles on the truck, but I replaced it in December , 2016

Also check you’re valve cover wiring connector.

That's great info on the ICP sensor.
My SES light is the one that's on--not the CEL--and I haven't tried to re-set it to see if it comes back on.
While checking my nine pin connections for the injectors and glow plugs, I noticed the wire insulation near the connections has started to fail. I'm wondering if that could cause the light to come on and maybe even cause the shuttering (which it hasn't done in two days). I'd like to be able to wait for warmer days to pull valve covers, replace the through-the-valve-cover connectors, and maybe replace glow plugs.

You get more responses if starting your own thread. Many folks (me at least) overlook resurrected threads since it’s usually done by accident (that great “related threads” feature on FTE 🙄 ).

Be careful buying parts on Amazon/eBay and such. There are very convincing “Motorcraft” fakes out there. We generally recommend only purchasing from well respected trustworthy vendors. CNC Fab, Riffraff, Ford dealer

In regard to your question. I would recommend pulling the code to see what it’s not happy about. FORScan and a Bluetooth dongle will get you there pretty cheap. There are multiple sections on FORScan in the Tech Folder (sticky at the top of our forum) and this thread as a FORScan class.

Thanks, Terran & Jason.
I have a great NAPA here in Taos that treats me well and they had an ICP sensor with a new pigtail--IN STOCK--so I got it, installed it after work, and my wife and I took it for a successful test drive, returning with a pint of ice cream. It doesn't get much better!!

I ordered new nine-pin connectors as well and will replace those later.
