My 2001 Powerstroke dies while at idle or during deceleration. The dealer can't figure this one out. There are no codes to show what's going on so they put a black box ("flight recorder") in the truck that whenever this happens I hit a button and it records 30 seconds prior and 15 seconds after. The engine dying is periodic and there is no pattern to it other than it's always while idling or decelerating. Thank goodness it's never happened while I'm on the accelerator.
Anyway, it happened a week after I put the flight recorder on while I was decelerating, and then two days later while I was stopped. The dealer read the flight recorder and wouldn't you know it...NO CODES! They've checked out the exhaust backpressure sensor and the CPS. Neither of these items is the cause of my problem. Again, there's no rhyme or reason to this...it can happen when the engine is hot AND when the engine is cold. When it does happen, it ALWAYS happens when I'm at a stop or the car is going 5 mph or less and I am not accelerating.
Does anyone have any comments on this? |

Sounds like the Cam Position Sensor all the way,had those go on me while driving the old late 90's International T444E 7.3's while sitting at a major intersection fully loaded with cargo and just going down the road which is more scary due to that when the engine is not running well theres no power steering and you have to be The Rock to turn the wheel 
Some people say they're adjustable well in fact they're not,it has to be replaced.
Take the truck back and talk to the Diesel technician that's on staff and have them replace the CAMP sensor.
The International Dealer will say the CAMP sensor is most likely the cause.

Thanks for the comments. First, more times than not the car WILL start right back up. Only on a few occassions has it taken a couple of tries to get it started.
Secondly, I mentioned above that the CPS (Cam Position Sensor) has already been checked out by the dealership. In fact, they told me that was the first thing they checked and that this was not a problem.
By the way, I'm at 55,000 miles so only the engine warranty applies. Been doing it for about 6 months or so.
Any other ideas or comments? |

My cam position sensor went out about two weeks ago. It first happened completely out the blue while coasting along at about 40mph. Engine died and it would not restart.
At the dealership a couple days later it started right up, I drove it for several miles, and it died again. Tried starting it up -- it ran, then died again. Only after that first time the engine died it didn't start up right away.
Your symptoms sound similar and it is definitely an electronics problem. If it's not the cam position sensor itself then I wonder if it's the wiring to the sensor that somehow is shorting out or has gone bad.
When my cam sensor went out it didn't trip any codes in the computer so it was a big mystery for the dealership I went to as well. It was only until I suggested that it was the cam position sensor that they replaced it and everything worked. When they did specifically test the sensor, the mechanic said that it was bad. Make sure they are checking the sensor itself and any wiring to it to verify it's all functional because it doesn't always generate a trouble code in the computer.

Okay, here's what the dealership found....
They say they checked the CPS directly, not through the computer, and found no problems. In fact, they only found one thing and that was the external water fuel seperator heater. Apparently, there is an internal and external heater at the fuel filter and the external appeared to have some damage to it so they replaced it. Warranty paid for it, less the $100 deductible. They're really thinking that this is only going to be by process of elimination and thinking that somehow my remote starter is causing the problem or that they may have to put a brand new computer processor in the thing to the tune of about $300 bucks!
By the way, everything that you fella's have noted has been checked. Now for the latest...
Well, I picked it up last night and this afternoon while sitting at a stop light it died on me!!!! Man this is making me crazy. Called the service department and they're suggesting removing the remote starter even though I never use it in the summer. I think this is crazy. If it happened at any time and not just at idle or stop I might agree. To be safe, and based upon what everyone is saying, I'm thinking about having the CPS replaced anyway, but they tell me it's going to cost me about $300.
What do you guys think? If I replace the CPS can a non-gearhead do it? If so, how? Where do I pick up a CPS? I'm not TOTALLY mechanically challenged. Thanks for your insights. |

i have had three of my customers with similar problem. all three had a bad CPS. the last two could not be detected by Ford scanners. as far as your remote start, they are known to be trouble makers.

Peter,
$300 seems right if Ford does it but the Cam Position Sensor is covered under warranty if it indeed was the culprit. There was a discrepency at the dealer I went to and they claimed the sensor was not covered under the Powerstroke 100K warranty or my extended warranty. I challenged their claim...to make a long story short, they had to call Ford directly to get an answer -- It's covered under warranty.
With regards to the remote starter -- the dealership tried pulling the same BS with me. I have an alarm system with remote start...the first thing (before even trying to diagnose it) they suggested was that it could be an issue with the alarm. I really hate when they do this but it is unfortunately one of the downsides of having any aftermarket component on your vehicle when a dealer is trying to solve a difficult problem.
A cam position sensor can be purchased for roughly $125 I believe. They can be installed on your own. While I have not performed the install myself, from what I have heard it's one bolt that needs to be undone. The difficult part is that you just have to contort your arm/hand into the space to do it while laying under the front of the vehicle. The Ford technician that replaced mine said it's to the left-hand side of the timing chain cover.

Spoke with the dealer this morning as my truck died two more times last night . At least now I can say for certain that the only time it dies is when I have my foot OFF of the accelerator. Anyway, I spoke with the Dealership and because the tests to the CPS showed no problems, they won't replace it under warranty. They tested it both on and off the computer (i.e., directly tested the CPS with no problems showing). Apparently they think that there was a chip installed on the truck before I purchased it and even though it is no longer on the truck they think it may have screwed up the computer processor and they want to replace that. Of course, they say that is not covered under warranty. I'm thinking about replacing the CPS myself. Does anyone know where I might find some diagrams about how to do this and where I might purchase one? |

Peter,
Go to another dealer. This one is giving you the runaround. They "think" a chip was installed? Please. Without evidence they can't replace it without covering it under warranty.
Is there a Ford dealership in your area that specializes in selling fleets of vehicles (i.e. lots of SuperDuty trucks)? These are the guys you need to go to as they'll have the best diesel mechanics on staff.
Even the dealership I went to who was diagnosing my cam position sensor said they would install a new one even if the current one checked out. None of this BS about not covering it.
This is so frustrating. You almost have to know somebody in order to get quality work done. Like I said, try another dealership.
