What are the symptoms of a faulty electronic accelerator pedal?

[AbigailLee]

The symptoms of a faulty electronic accelerator pedal include unresponsive acceleration, slow acceleration speed, unstable idle speed, etc. The electronic throttle control system mainly consists of the accelerator pedal, pedal position sensor, ECU, data bus, servo motor, and throttle actuator. The position sensor is installed inside the accelerator pedal to continuously monitor the position of the pedal. When a change in the pedal position is detected, the sensor instantly sends this information to the ECU. The ECU processes this information along with data from other systems, calculates a control signal, and sends it to the servo motor relay via wiring. The servo motor then drives the throttle actuator, while the data bus is responsible for communication between the system ECU and other ECUs.
