In a conventional internal combustion engine, only electrical controls are used to prepare the fuel mixture. All parts must operate flawlessly in order for the vehicle and its components to operate correctly. Road safety may be negatively impacted by the failure of specific components. The purpose of the study was to ascertain how much the malfunction of particular electrical components affects how the vehicle operates. The vehicle's individual electronic parts were removed, and the engine power was then assessed. The primary determinant of a vehicle's technical condition is thought to be its engine power. The preparation of the combustion mixture was affected by the individual component disconnections, which reduced the vehicle's performance. A vehicle with an in-line four-cylinder engine was used for the experiment, which was conducted in a lab setting. This vehicle's eight components were gradually disengaged. The change in engine power was observed while they were disconnected. The measured values were always evaluated in terms of an automobile that had no defects and was in excellent condition. The study's findings demonstrate that there are circumstances in which a vehicle's usual operation is adversely affected when one or more of its electrical components malfunctions.
