What are the symptoms of an electronic throttle pedal malfunction?

[JamesonFitz]

The symptoms of an electronic throttle pedal malfunction are: 1. Damage to the electronic throttle pedal; 2. The dashboard warning light will illuminate; 3. The car's throttle pedal becomes stiff and produces abnormal noises when pressed; 4. The throttle pedal does not return to its original position after being pressed; 5. Failure of the throttle pedal sensor; 6. The ECU cannot detect the throttle position. The working principle of an electronic throttle is: The electronic throttle controls the opening of the throttle valve via cables or wiring harnesses to achieve automatic control functionality. It replaces the traditional throttle cable or linkage with wiring harnesses or wires, installing a miniature motor at the throttle valve to drive the throttle opening. This is known as drive-by-wire, where wires replace the original mechanical transmission mechanism.
