What are the symptoms of a faulty electronic accelerator pedal?

[Muhammad]

Electronic accelerator pedal failure generally results in symptoms such as unresponsive acceleration, very slow acceleration speed, or unstable idle speed. Below is relevant information: 1. The electronic throttle control system mainly consists of the accelerator pedal, pedal displacement sensor, ECU, data bus, servo motor, and throttle actuator. The displacement sensor is installed inside the accelerator pedal to constantly monitor the pedal's position. 2. When a change in the accelerator pedal's height position is detected, this information is instantly sent to the ECU. The ECU processes this information along with data from other systems, calculates a control signal, and sends it via wiring to the servo motor relay. The servo motor then drives the throttle actuator, while the data bus is responsible for communication between the system ECU and other ECUs.
