Question 7.3 no throttle response

Hello, newb question,
I was at a stop sign the other day and no matter how hard I pushed the accelerator pedal there was no response.

I have a 97 ex cab 4x4 7.3 with 240,000 mi.

This thing was running perfect b-4 this,wile I was sitting there stranded I pulled the throttle position sensor plug and tried jumping a couple pins
( mistake ) it died and now the check engine light is on. I also pulled fuse
# 13 I think, in cab fuse panel top center fuse 15a, any way after messing with it for a bit while traffic gave me a hassle it started to work.

I did a search here and the factory did a bulletin for the ( IVS ) Idle validation switch but this bulletin is from 95, does it apply here ??

It states to replace pedal and switch assy as a complete unit, can I just get the switch ? And how do I reset the check engine light ??

The truck runs ok now but I don't want to be stranded again.
Thank you so much,
Scot

When mine did the same thing at a stop light it turned out to be the accelerator pedal assembly, replaced it and all was well again.

Another more recent but similar post says throttle position sensor and it will be enough, is this true or do I need the whole pedal assy ?

Im not sure about yours but mine came as an entire pedal. The IVS as I understand is in the position sensor. I would just buy a new one and be done with it. Im on my second one now. It only gets worse, first few times are probably months or weeks apart, after a while it will start doing it every time almost. Its pretty embarassing trying to roll through an intersection at an idle with long lines of traffic behind you lol.

Thanks YAMAHAMMER, I did see a Ford bulletin ( replace entire throttle pedal with sensor and IVS ) on that but it was posted in 95 so my guess was it would be for earlier versions and that by 97 it would be corrected ??
Napa did have the trottle position sensor but no list for the Idle Validation Switch or pedal assy. the closest dealer to me is about 50 mi haven't made it there yet.

No Throttle... Dead pedal

Sorry, this is a bit of a re-post but it crosses threads...

I've got NO throttle response and this thread says to replace Throttle Assembly and another thread here says there is a bad wire in the column shifter. I have pulled the column shifter and I don't see any 'obvious' signs of a broken/bad wire (insulation is still intact and looks okay so I can't actually see the wires).

I'd rather not start throwing $100 bills at the problem...is there a way to better diagnose? My problem comes and goes (but it's getting worse and more frequent) so I've eliminated the possibility of a blown fuse (but please tell me if I'm wrong)

HELP!!!!!!!!!!!

There is a way to test the pedal assembly and what the outputs should read as you depress the pedal. You will need a digital multimeter. I am not sure what the readings should be but someone on here had posted them before, hopefully they will chime in and let you know. It's been a while since I did mine and I don't remember where I put those #'s at. Getting tha old timers disease you know.
