Ignition coil failures are caused by worn out spark plugs that fail to transmit electronic signals in a functional and fluid manner. This creates a disruption in the regular flow of power across the ignition coil and makes the engine lose power. It is less common but still possible that the rotor the ignition coil rests on breaks and reduces the function of the power circuit.
The ignition coil is the primary tool used between the battery and the rest of the engine in terms of transmitting electrical power from one point in the machinery to the entire combustion process. This device sits on a high-powered rotor that allows for fluid movement as the coil transfers electricity along the cylindrical path of its metallic frame. When spark plugs fail to transmit electrical information in the right sequence and frequency, this causes significant issues that result in ignition coil failure.
An ignition coil failure is easy to detect thanks to the visible ways it impacts the engine. Cars and trucks with ignition coil failure experience backfiring, misfiring and problems with getting the vehicle to start in the first place. When drivers encounter issues with maintaining power in the automobile, it is likely that the issue is an ignition coil failure.
