1 Answers
The symptoms of a broken car accelerator pedal include: 1. Weak acceleration; 2. Unstable idle speed; 3. Malfunction indicator light turns on; 4. The accelerator pedal becomes stiff or fails to return after being pressed. The accelerator pedal, also known as the throttle pedal, is part of the car's fuel supply system. By controlling the amount of pedal depression, it regulates the engine throttle opening, controls the air intake, and the computer adjusts the fuel supply, thereby controlling the engine speed. 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 its position.
