What's the reason when the accelerator pedal feels stuck and can't be pressed down?

The reasons why the accelerator pedal feels stuck and can't be pressed down include: 1. There is a foreign object under the accelerator pedal, preventing it from being pressed down; 2. For mechanical cable-type accelerator pedals, the cable is stuck or frozen, making the pedal unable to be pressed down; 3. The accelerator pedal is not sensitive. The accelerator, also known as the "throttle" or "gas pedal," is a control device that regulates the engine's power (thrust). In piston-type aircraft engines, the throttle controls the carburetor's throttle valve opening to regulate the cylinder's filling volume, thereby determining the engine's output power. In gas turbine engines, the throttle controls the metered fuel flow of the fuel regulator, determining the thrust produced by the engine.
Last time my car's accelerator pedal got stuck too, it was terrifying! It might have been a snack wrapper under the seat or the floor mat shifting, rolling up and jamming the pedal. The worst is when ice melts and refreezes in winter, it can literally freeze the pedal solid. My advice is to brake immediately to slow down, pull over, and check under the pedal to remove any obstructions. If it's a broken spring or rusted throttle cable, be extra careful when pressing down to avoid causing more damage. Before long trips, it's best to clean out any clutter in the car and check the pedal's flexibility. A friend of mine has encountered this issue multiple times, all because they were too lazy to clean their car, leading to dangerous situations where they couldn't accelerate during emergency braking. Regular maintenance of small details can prevent major issues. I spend a few minutes each month cleaning around the pedals—too much dust can affect their rebound. Remember, safety first. Stay calm and follow the proper procedures if something happens.
I'm quite familiar with throttle sticking issues. Common causes include foreign objects getting stuck in gaps, like keys, small stones, or slipping floor mats. Or mechanical failures in the pedal assembly, such as aging return springs losing elasticity or insufficient lubrication in linkage joints causing stickiness. Electronic throttle models are trickier - dust accumulation on position sensors or poor wiring harness contact can send false signals. At a previous car meetup, many shared experiences of pedals freezing in winter; anti-freeze spray can prevent this. Recommended practice: After turning off the engine, manually test pedal rebound. If resistance is high or feels loose, clean thoroughly and use WD-40 lubrication if needed. Don't neglect this small component during routine maintenance - keeping the car interior floor clean is the long-term solution. Safety reminder: If sticking occurs on highways, immediately activate hazard lights and pull over to the right. Avoid forcing the pedal to prevent loss of control. Develop a habit of regular self-checks for peace of mind.
