Need your Help- Hesitation/Miss Issues

[XR-2001]

Guys,
Got a problem on my hands... My 01 7.3 w/160k started jacking with me again yesterday. While driving, all was well, sudden miss began happening. I got 'service engine soon' , 'wait to start' and 'water in fuel' lights all at once as the motor basically died, then picked back up. The miss is only for a couple seconds at the longest.Like a fuel cut off or complete electrical shut off for a second or two.

I thought being winter and pretty cold here for the last few days, that I may have water, so I drained the bowl, went on about my way. But it happened a few more times. Bought a new filter on the way home, Drained bowel fuel into dry glass jar,, no floaties or water, pulled old one, no water visible in the bowel. Installed new filter, same things happens.

It may only do this once in a few miles under all conditions, idle - cruise and under load.

I did try and search this issue before posting. I see people talk about IPR, CPS but no same issues as I have and no real feedback on the solution to the other folks problems. I had the CPS recall and that was changed out at Ford 8 months ago. Not sure which one they installed, gray or black one....

I do not have a scanner, but will try and get to a shop and have the truck scanned today.

Any feedback would greatly be appreciated guys ! ! !

Thanks, RB

I found this on Guzzle's website..... hopefully I can find a CPS he references locally and solve the problem.
Maybe someone else can use this info as well..... RB

Pasted From Guzzle's --------

The CPS (Camshaft Position Sensor) is one of the weakest links on the Ford 7.3 Powerstroke engines. The sensor has a high failure rate and common symptoms include having the engine die while driving as if you turned the key off just to have the driver pull over and restart without any problems; periodic 'hiccupping' of the engine; complete failure of the CPS can kill the engine and will not let it restart.

Well,, Installed a new CPS yesterday, truck ran fine, no issues. Dang thing did it again a while ago at lunch..... Any ideas before I have to pay for a shop scan on this thing ?

Thanks, RB

My CPS was also going out, so i replaced it last Thursday. Truck ran fine all day, then I was headed to a funeral on Friday and upon accelerating it hiccuped again. I suspected the CPS. Drove all the way to abilene from DFW, no problems, and then leaving my aunts house headed home and truck completely stalled while going down the road. It would turn over, but no fire. I unplugged the CPS and replugged it in, and it tried to crank once.

Apparently you CAN put too much di-electric grease on the electrical connector to the CPS...
I pulled off the plug, hit it with some PB blaster, also sprayed inside the CPS connector, plugged it back in and truck cranked right up and ran fine all the way home. Started fine this morning, and been running fine ever since.

I don't know if you did the same thing, but that's what worked for me.

Thanks. My old gray CPS had no di-electric grease on it when i pulled it out. I installed the new gray CPS I did not lube it. Still had the issues. I put a small amount of di-electic grease on the new CPS yesterday evening, still had hiccups.

I pulled the ICP connector away fro the ICP sensor, and found the entire fitting filled with motor oil... I think this is it,,, cleaned out sensor and the connector with contact cleaner, same issues with hickup.

I do not believe that the ICP was filled with a mere misting from perhaps the CCV as my motor bay is typically very clear of oil mists.

Is it possible for the ICP sealing capibilities to fail and allow oil to seep up thru it into the connector ? ? .................This is driving me nukkin futs.... ! ................
Just dumped a new BTS in her and can't afford to keep tossing money at it. I am trying to find someone locally that can scan it for me today...

Appreciate it......Russ

Both the ICP and CPS should be completely sealed units, my faulty CPS did have oil inside the connector itself when I pulled the plug out.

I would assume the ICP should be the same, so if you have oil inside the connector, very probable that it is faulty as well.

Im not 100% sure of this, but it makes sense.

Here's a writeup on a similar subject. Sounds like it could be your problem.

UPDATE:

Apparently my truck is now stalling, no hiccups or misses, it just is driving down the road and shuts off.

I did notice that I bought the Borg Warner replacement CPS which is the grey colored one. I recently heard the grey one has problems. If I pull of the electrical connector to the CPS, hit it with some PB blaster and reinstall the connector, the truck will start right up.

So I am now beleiving what I am hearing. So questions is, where do I get the black CPS, from Ford house?

[XR-2001]

Thanks for that link to the bad sensor symptoms...... Looks like a new ICP is in order. I'll get the scan anyway to make sure..


During the Ford recall, they replaced my stock CPS with a gray one. The local International dealer had the gray one in stock. I have heard of the dark gray ones and the infamous black one.

I think Diesel O-rings has some black ones left.

edited part ---- just spoke to Bob, it will be a few days before he can get new Black CPS's out the door, he has them, but not in hand, he has to get them from storage which apparently is not local.....

[XR-2001]

Well, a scanning is in my near future I reckon............ changed out the ICP,, truck does 85% better,,, still has the slight hesitation like before but now there are no idiot lights coming on when she stumbles.

Gonna swing by and have her scanned toady after work hopefully..
