2014 M126GX RPMs won't Rev up and Tractor Won't Accelerate

Got the info I posted from my WSM. Signals from the 3 feed into the ECM. It’s hard to see anything other than the speed limiter doing its limiting job or an ECM problem. Otherwise the foot pedal sensor and hand engine speed sensor would need to fail simultaneously.

So it ended up being a simple fix. Turns out my rev limiter control dial was broken so even when I turned it it was not working. Replaced with a new dial and back in business. Appreciate the help from all!
