The early military HMMWVs like my 1986 M998 have the other kind of
"drive by wire", where the pedal is connected to one end of a piece of
wire, and the other end is connected to the throttle linkage on the
injection pump. :-) In other words, it's a simple mechanical linkage.
There's no computer, and there's no sensor. The injection pump is
mechanical, and the only electrical requirements to keep the engine
running are the fuel cut-off solenoid and the cold advance solenoid.
Even the fuel lift pump is mechanical in the military HMMWV.
I don't know if the pedal itself is the same. I can't comment on later
military HMMWVs.
I hope this answers part of your question!
