Stalling Diesel
My 2001 Diesel Excursion was stalling at idle (either at a stop or <5mph). It did this a couple dozen times at random. Since the warranty is expiring soon, I took it to the dealer last week. They said "no codes, so no problem."
The plot thickens -- After the dealer, I was driving and the accelerator stopped working. Pressed it to the floor and nothing. Crawled along at idle for 30 seconds. I stuck it in Neutral, revved, and it was fine. Then I took it on a trip. It did the idle stall, but also a stall in freeway traffic. Fast lane doing 70 and it stopped. Tach showed 0 rpms. In two seconds, it restarted on it's own. Made me feel warm and fuzzy. Also, there are occasional 'misses' while cruising. Tach dips and recovers immediately.
Any thoughts? I have seen the threads on the CMP sensor and wonder if this could be it. Thanks for any ideas.

Sounds like you have Two sensors playing up. The CMP sensor, and the Throttle position sensor. (if you have the adjustable pedals, there is a recall on them.)
Change the two of them, and the problems may well be a thing of the past.

There are two switches on the accelerator pedal, either of which could be the problem for the returning to idle problem. There is the throttle position switch and the idle validation switch. If the IVS sticks the truck will not go above idle because it thinks the pedal is not pushed down. I think it's a safety thing. I've heard of that switch sticking. It's the one you hear click as soon as you push on the pedal.
The other prob sounds like CMP to me from what I've read here.

Also for the accelerator pedal switches it doesn't matter which is bad because you can't buy the switches themselves you have to buy the whole pedal assembly which is 185 bucks here at my dealer.

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?

cant help with the problem but acode will only be recorded if a component operates outside it working parameters eg if something works on voltage or resistance say between 1-8 if its supposed to be reading 2 and its 7 it has not operated outside normal readings so no fault will register

I've heard the cps will not throw codes. If this is the case yours could well be going bad. The dealership can check it when it's working and of course it will check out. Have they ever checked it when the truck has just died? I'm guessing not.

Resolution: I returned the truck and they were able to get some codes. They replaced the Crankshaft Sensor and the Throttle Position Sensor. Seems to run fine. After hearing of so many issues with the CMD, I am suspicious that is problematic also.
I identified this before 36k and got two different people to assure me that the warranty would cover it. They still tried to waffle and wanted to charge me $100 under the diesel coverage.

my cps went bad gradually. over the period of one month, with ever increasing frequency, the motor just dies and miraculously restarts itself within about 1/2 a second... eventually though it wouldn't restart itself and the service engine soon light came on and stayed on. the ford dealer pulled the code from the computer , replaced the cps, and $ 100.00 deductible dollars later, my diesel is running fine... ( 97,000 miles.... )
my point is that it took a while for the sensor to fail "enough" to throw a code out to the master computer. so be patient... and
eventually it will be there......
