On my 2000 7.3, I changed the pedal assembly 7-8 years ago with a new ford oem unit. A couple weeks ago, I got the random no throttle response from idle again. Of course I couldn’t duplicate it when Hooked to my scanner but the little switch seemed like the likely culprit. Even cycling it a couple hundred times and watching the response on scanner, it never acted up.
The oem unit seems to be not available anymore and I really don’t have a lot of faith in aftermarket units. I remember years ago there was a switch you could buy for a couple bucks but of course it is no longer available either.
I got my old pedal assembly out from years ago and pulled the switch and started looking for a suitable replacement. I found one on Amazon.
Exact same dimensions. Only differences is that it has 3 wires so it can be used for NO or NC and the pigtail exits from the side corner rather than the bottom. $10 for 2 of them seemed like a no brainer to try.
I finally put it in today and it works fine. I don’t think it is as high quality unit as the oem but if it lasts a while for 5 bucks I’m good. It isn’t hard to change.
taking the unit off is self explanatory with a t20 driver. You have to grind off the molded plastic to remove the oem switch from the bracket and will need some 2mm screws (I think I used 16mm length) to attach the new switch to the bracket. A full kit of 2mm screws of various sizes with washers and nuts is also on Amazon for about $6.
the 3 wires on the new switch are blue, black and grey. Clip the blue wire off or tie it out of the way, it’s not needed. I soldered and heat shrunk the grey and black wires to the oem wires (doesn’t matter which color)
you could crimp connect them I guess but I would leave some extra length if i did that so they could be held out of the way.
I didn’t take pics of the progress but the finished product pics are below.
the switch description on Amazon is :

Joinfworld Waterproof Micro Limit Switch with Hinge Lever 6A 12V DC Lever Microswitch SPDT 3 PIN 5A 250VAC with Pre-Wired - 2 Pack

I hope this helps someone else save a couple hundred bucks.

OEM pedal assembly isn't available now? Yikes. This is good to know though in case I even run up on this little gotcha.

 

Our trucks are getting into '32 Ford territory.

 

Now we need to find an aftermarket solution for the APP potentiometer too.

 

Been driving it a bit and no issues so far with this fix.
even decided to replace the fuel sending unti and ditch the umbrella pickup so I have a working gauge for the first time in 14 years
