What causes the accelerator pedal to stop working?
2 Answers
If the accelerator pedal stops working, it is likely due to a malfunction in the vehicle's throttle body. Replacing or cleaning the throttle body should resolve the issue. Here are some precautions to take when cleaning the throttle body. Choose a reliable cleaning agent: Do not use substitutes like carburetor cleaners. Instead, purchase a dedicated throttle body cleaner to prevent future corrosion of the throttle body. Select an appropriate cleaning location: Cover all open pipes to prevent dust or debris from entering. Avoid windy or excessively breezy areas to prevent sand and dust contamination. It is best to use a flexible screwdriver when loosening the throttle body screws. Prevent cleaning fluid from corroding other components: During cleaning, ensure the electronic components of the throttle body remain facing upward. Do not invert it, as cleaning fluid may enter the electronic parts, causing short circuits or corrosion.
I've been driving for decades and have encountered many instances where the accelerator pedal suddenly stops working. The most common issues are aging and snapping of the throttle cable or the throttle valve getting stuck, especially in older cars that are prone to rust and dust accumulation. Fuel pump failures are also quite common; in such cases, the car might not start or have weak acceleration. A friend of mine had to replace the fuel pump to fix this. Another time, a clogged fuel filter caused insufficient fuel supply, making the car unresponsive when stepping on the gas. Don't overlook the fuses—check the relevant ones in the car's fuse box to see if they're blown. Accelerator system failure is a matter of driving safety; never push through it. Pull over safely, inspect the issue, or call for roadside assistance to get to a repair shop. Regular maintenance, such as cleaning the throttle valve and replacing the fuel filter, can prevent minor issues from turning into major problems.
