Ok, is this the CPS I am hearing about?

Help! While driving this morning to work in all the glorious snow & heavy slush my 2002 F-250 7.3 PS scared me. I noticed the accelerator seemed to take a little more to keep it up to speed (seemed to dog out and slow down) and when I exited the expressway I noticed all of a sudden I had no accelerator input. The little light on the cluster came on indicating an engine problem. After blipping the throttle a couple more times it finally caught and was working, more or less. (intermittantly) When I finally reached work (about 1-1/2 miles later) the engine quit responding totally and the engine light is on. After shutting the engine down and restarting it will still idle but no throttle. (light is still on) I have been reading that the CPS is a pretty common problem. What do you guys think? I work as a fire fighter so I will be here at work for 24 fun filled hours. Coincidentally, the truck did almost the same thing early in the spring last year. I took it to the local Ford garage and (of course) they could not duplicate the problem. Over the summer it was fine. It seems to me that this problem happens whenever the truck is in very wet condiditions. Again, do you gentlemen think this is indicitive of the CPS?

Thanks for your input.

Not sure if its the cps or not, but if your dash light is lit you have thrown a code. Do you have anyone that can scan your truck for you. Get the truck scanned and see what code comes up and post it up. It will be a 4 digit number. If you know someone that has a tuner most will read codes.

This doesn't sound like a CPS problem to me. Generally, a bad, or malfunctioning CPS will cause the engine to die all together. Since it sounds like your is still running, but not responding to throttle imputs, I would be more inclined to think that it was a different problem.

That's the best I can do, however... and I may be wrong. One of the terrific techs who know this stuff way better than me should be along soon to help you more.

Accl pedal

The throttle position sensor is in the pedal assm. That is pretty common.

Your problem is very similar in characteristics to what I was experiencing with my 7.3L and it was indeed the CPS. I would have never thought of this on my own and I give credit to Scott for clueing me in to the whole CPS thing.

The not so funny thing about all of this was that my local Ford dealer was trying to ding me for a $1000 ICM part...stating that the CPS was not capable of producing the problems of loss power, stalls, and no starts at all (at times).

For the heck of it, I would start with the replacement of the CPS since it is a relatively inexpensive part.

For me, it was the answer. My truck runs great ever since the fix...and I was chasing mythical fuel problems, injector problems, you name it...until Scott straightened me out.

Hope that sharing my experience is helpful!

I'm going to go with the CPS, and even if that is not the problem, at least you will have a spare, sooner or later your going to need it anyways, usually in the middle of the night in a rain storm, far away from civilization hahaha.
