The electronic throttle is superior to the pull-wire acceleration control, because the electronic throttle knows the power demand of the engine by calculating and analyzing the input signal of the accelerator pedal position, and converts this information into the torque of the engine through various actuators. Due to safety, fuel consumption and other reasons.
The engine control unit detects the electronic throttle system to sense the occurrence of the fault, and displays it through a small yellow light installed in the instrument cluster.
