Why Does the Accelerator Pedal Vibrate When Honking the Horn?
1 Answers
The horn is too close to the body, causing resonance. Resonance solution: Adjust the position of the horn on the car. If the accelerator vibration problem persists after repositioning each horn, it indicates that the old horn is damaged and needs to be replaced with a new one. Check the horn installation position: First, observe whether the horn plug is rusty. The car horn is installed inside the front bumper, directly below the headlight, with the bass on the left and the treble on the right. Then check the engine mounts, exhaust pipe, including the catalytic converter. Dirty, worn, or incorrectly installed mechanical parts coming into contact with the car body can cause the accelerator pedal to vibrate.
