What Causes the Accelerator Pedal to Become Heavy?

[LeIvan]

There are several reasons why a car's accelerator pedal may become heavy, including obstruction by foreign objects or excessive spring tension. Below are detailed explanations of these causes: Obstruction by Foreign Objects: The primary factor causing an electronic accelerator pedal to become heavy is obstruction by foreign objects. Therefore, when inspecting an electronic accelerator, the focus should be on checking the pedal area for any blockages or jams, which can then be cleared. Excessive Spring Tension: Most car accelerator pedals are equipped with a spring underneath. The main function of the spring is to return the pedal to its original position. However, if the spring tension is too high, it can cause the accelerator pedal to become heavy, necessitating the replacement of the spring.
