The electronic throttle beeps.

1. Throttle controller failure: The failure or aging damage of the throttle controller itself may lead to its unstable operation, thus causing abnormal sound.

2. Abnormal power supply voltage: Unstable voltage will lead to unstable controller and abnormal noise.

3. The throttle itself is faulty: If the mechanical part of the throttle is faulty, such as a loose spring, there may be a buzz.
