The accelerator rod links the accelerator pedal to the throttle, the valve of which controls the flow of air in your engine and in turn dictates the amount of fuel released into your engine.
The accelerator rod is located under the accelerator pedal in the footwell of your car.
The accelerator rod plays a major role in making sure the throttle valve is able to open fully and the flow of air and fuel in your engine is regulated. A good quality, working accelerator rod will enable smooth functioning of the accelerator pedal when you press your foot on it and a steady, gentle spring return on the accelerator pedal when you release your foot.
An old or worn out accelerator rod can cause problems by not producing adequate force to spin the throttle properly which in turn prevents the throttle valve from opening sufficiently. This means the amount of fuel entering the engine of your car is not being regulated effectively, causing the accelerator pedal to stop working properly. If you are experiencing problems when using the accelerator pedal, seek advice from your mechanic about whether you need to buy a new accelerator rod.
