Can someone please explain?

Sure, in the context you describe they are obsolete. Much better ways than a worm gear potetiometer to self adjust. Now instead of replacing components you replace a board completely.

Back to an APPS in these trucks, what could be used to replace the APPS that has to take a human usable mechaincal input and translate that to a digital signal to control engine rpms?

To use a HE sensor you would need something like a gyro stabilizer that would react to mechaincal input to translate a movement. Something like gyros stabilizing a gimbaled engine mount on a launch vehicle for minute thrust adjustments, or even a cutting edge fighter jet where minimal movments get expanded and multiple systems are effected to make a simple turn.

Lets face it, our TV's are higher tech than the control systems on these trucks, they simply AIN'T rocket science and Dodge did not contract NASA. :-laf

Plain and simple, we got cheaped.

Still the best truck I have ever owned!

I read somewhere years ago that the unit under the battery is a hall effect type. Now I can't find it anywhere, so maybe I've been wrong all this time.

It could very well operate on the same principals as a Hall Effect sensor but it is still a potentiometer, a contactless potentiometer to be exact. It actual contains a Hall Effect sensor to generate the linear or algorithmic voltage across a range of rotation.
