What is the reason for the large opening of cable throttle valve?

The large throttle opening is generally caused by excessive carbon deposition in the throttle. Excessive carbon deposition will lead to engine idling and flameout. When cleaning the throttle, use carburetor cleaner to clean the sludge in the throttle body, especially around the throttle. Excessive sludge will fill the valve gap in the throttle body.

Function of cable throttle valve

The cable is connected to the end of the accelerator pedal of the traction accelerator and leads to the accelerator. The action of stepping on the throttle directly controls the throttle through the cable, just like the cable of the handbrake. The structure of the accelerator pedal 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 connected to it. All the actions of stepping on the accelerator are converted into electrical signals and sent to ECU. The electronic accelerator pedal has a complicated structure. Because there is a potentiometer inside, it is lighter to step on and the overall resistance is the same. Moreover, the electronic accelerator pedal is very accurate and there is no neutral position. Step on your toes lightly, but don't move, otherwise it will generate a signal and increase the engine speed.
