What's the difference between cable throttle and electronic throttle?

There are two kinds of throttle valves in cars, one is cable type and the other is electronic type, so how to distinguish the throttle types of your car? The easiest way is to observe directly. There is a cable on the accelerator pedal of the cable-type accelerator, and the accelerator itself can also see the cable. The electronic accelerator pedal is a potentiometer and there is no cable on the throttle body. In addition, if you drive a car with a cable throttle and an electronic throttle respectively, you can also experience the difference between foot feeling and driving feeling. The difference between the accelerator pedal and the cable accelerator is that a cable is connected at the end of the accelerator pedal and leads to the accelerator. When stepping on the accelerator, the accelerator is directly controlled by the cable, just like the cable of the handbrake. The accelerator pedal structure is relatively simple, purely mechanical, without plugs and wires. The electronic accelerator is adapted to the electronic accelerator pedal, which is a potentiometer with many wires on it. All the actions of stepping on the accelerator are converted into electrical signals and transmitted to ECU.
