Does everybody know how a car works? Basically, anyone can answer this question; however, if we delve into the technical details then not everything is so obvious, or at least not to everybody.

Here, we want to ask about an element that is found in a car and is called potentiometer of the accelerator pedal. We depress the accelerator pedal, the car accelerates and this is obvious. But on what principles does it work? And here enters the accelerator potentiometer mentioned above.

Potentiometer, or otherwise accelerator gas pedal

    This is the element that is responsible for acceleration and also for slowing down on the road. It transmits information on the position of the acceleration pedal and thus information on the necessity to increase the engine speed and thereby accelerate. Furthermore, if we have to do with a car with an automatic gearbox, then this potentiometer also transmits information on gear shifts. If the accelerator pedal is depressed to the floor, this causes acceleration of the car and after some time a higher gear is engaged automatically. If this part becomes defective in our car then it is difficult to achieve proper acceleration and the car might respond in very different ways, we could colloquially say it goes mad. And therefore in a moment like this it becomes necessary to replace this part. Its cost obviously depends on the model of the car concerned and whether it is a new part or a used one. It is quite OK to go for a used one that will serve the purpose very well. Here we need to indicate the price. As already mentioned above, it is to a large extent dependent on the model of the car; however, can find something within the range of several hundred zlotys. This will be of course increased by the cost of replacement, which altogether means the amount to be spent is quite considerable. However, this expenditure is necessary as driving with a defective potentiometer of the accelerator pedal is not just a certain handicap but it can be simply dangerous. Before we buy such a part it is worthwhile to have a close look around the market as we might find a bargain.
