Unhappy Intermittent Throttle Unresponsive

Lately, and not every time, I get no repsonse from the gas pedal. I checked the connections to the drive by wire and nothing seems to be messed up. This is dangerous, since it can happen while pulling out. This morning, it happened after a long acceleration and right after that I felt it cut out several times while driving at steady speeds. Any suggestions??

pull the cover on the steering column and look at the wiring that runs from the shift lever down the steering column, it will more than likely be frayed about an inch and a half after where it comes out of the shift lever. there may be only one strand of wire showing, but when it contacts metal it will make your throttle pedal unresponcive....

I will check that before I leave for lunch. I hope it is that simple. Excursion has 153,000 on it and so far so good.

Me Too...

I've got a 2000, F350, 7.3 that is now doing this same thing. Sometimes I push the pedal, and it's fine... Sometimes it does nothing, and just keeps idling. I can't drive the truck anywhere right now, because it's acting up too badly to be safe.

I took apart the column and looked at the shift lever wiring, and that all looks good. I've also taken the two sensors off of the pedal assy, and cleaned the connections with compressed air... Although, they didn't look dirty at all, to start with. I looked at all the fuses in the dash and they were all fine, except for fuse 13. So I put a new fuse in there, but the pedal is still a problem. I don't know what fuse 13 is for... Maybe it was just a coincidence that it had blown.

What else would it be? What do I need to do? I looked up a new pedal assy, but it's 400 dollars, so I really don't want to have to replace that, unless I absolutely have to.

What do you guys think?

Maybe it's your map sensor? I have a tune file that disables the map, therefor leaving the truck disabled with out any throttle function. I think that's how it works! Not 100% tho

Is that easy to pop out and clean, then put back in? Or do I just need to buy a new MAP sensor?

I am running DP Tuner's, Infinity Tuner... But I hadn't considered that as being part of the problem. I doubt that has anything to do with this, though. But I guess I could try to re-flash the tune and see what happens.

Sounds like your pedal position sensor. If you replace it it comes an the entire unit, to include the gas pedal.

Yeah... But that's 400 bucks. Do I really have to do the whole assy? Or can you just replace the sensor?

I found a post on here, before, about someone who had just replaced the sensor. But now I can't find that post. I think the guy ordered the sensor for a van, but it's the same sensor... Or something like that.

Does anyone have a part number for those two sensors? I doesn't seem like there's anything else within the pedal that can really go bad. So why would you need to replace the whole assy?
