What are the symptoms of an electronic throttle pedal malfunction?

[Holly]

Electronic throttle pedal malfunction symptoms include damage to the electronic throttle pedal; the dashboard warning light will illuminate; the car's throttle pedal becomes stiff and produces abnormal noises when pressed; the throttle pedal does not return to its original position after being pressed; failure of the throttle pedal sensor; and the ECU being unable to detect the throttle position. The working principle of the electronic throttle is: The electronic throttle controls the opening of the throttle valve via a cable or wiring harness to achieve automatic control. It replaces the traditional throttle cable or linkage with wiring harnesses or wires. A small motor is installed at the throttle valve to drive the throttle opening, which is known as drive-by-wire, replacing the original mechanical transmission mechanism. Electronic throttle: The car's electronic throttle is essentially the throttle body, fully controlled by an electric motor. The electronic throttle accelerator operates through a signal amplifier installed on the throttle pedal, enabling throttle operation via signal transmission.
