re: those plastic "rivets", if there's sufficient meat below them, you can drill them out with a sufficiently small drill, then use small self-tapping screws to replace them ...

This is the sensor. Ford does not sell anything but the entire assembly.
This sensor repair is available at rock auto around $40.
Only 3 pins so you may be able to check the resistance on your by trial and error.

They are just 1/8" dia pins that are rounded over after they go thru the cover, not much to screw into. Maybe I can use miniature thread-forming screws and a very steady hand to drill the pilot holes.

My wiring diagram for 2002 7.3 shows 5 pins on the accelerator pedal position sensor...

pin 6 - red-yellow - power from fuse F2.45
pin 7 - red/lightgreen - to PCM pin 10
pin 8 - grey/white - to PCM pin 89
pin 9 - yellow-white - to PCM pin 24 (shows signal input inside pcm)
pin 10 - (no color shown) - to PCM pin 90 (labeled as Vref)

Pop the side off it, you will see where the resistance strips have worn spots on them.

I would get the non adjustable pedal and try to hack the sensor onto the old pedal assembly

Rock Auto shows a rebuild option, may want to look into that.

In my defense, I was unsupervised

General note:
For all those wanting a premium silicone sealer Kubota 70000-73764 is the best your gonna find. This is a hybrid gray silicone that uses solvent rather than acid to start the curing reaction, this makes it safe for aluminum and and any surface that involves coolant.

If I do take it apart, it looks like I might be able to reattach the cover with cable ties, although I'd really like to confirm the sensor is bad before I chance destroying it....

The RockAuto repair for my truck's year is for the non-adjustable pedal.

To anyone that's had one of these sensors apart: instead of me taking mine apart to hit it with electrical cleaner, would drilling a small hole in the cover and spraying into it work? This way, there would be only a small hole to plug vs. trying to reattach the entire cover plate.

I sprayed down everywhere I could on the sensor, let it dry overnight then put it back in, but still getting a CEL. The truck can be just idling (no pedal movement) and the light will continue to go on and off. Could this be an indication there's something else causing the occasional lack of throttle? I've tried pulling the trouble codes with the OBDLink app, but get nothing.

I decided to drive the truck to work today. It ran fine for the first 10 mile leg where I stop for coffee, but had several no-throttle incidents over the last 3 miles. At one point I had to coast it off the road, and sat there for 20 minutes working the pedal trying to get any throttle to limp it on in. It seems to loose throttle only when I back off the pedal completely, then throws a CEL. If I use my left foot for braking to maintain a little throttle, it rarely fails. Is this a sure sign it's the pedal sensor, or could it be something else?

Also, have any of you had luck using the OBDLink scantool app? I can connect it to the truck, but cannot pull any trouble codes. Since I'm getting a CEL there has to be stored codes, right?
