An ignition coil is a component of an internal combustion engine that provides the high voltage necessary to create an electric spark in the spark plugs, igniting the air-fuel mixture in the cylinders. A faulty ignition coil can lead to various engine problems, such as misfiring, reduced power, and increased fuel consumption.
Checking the ignition coil is a relatively simple procedure that can be performed using a few basic tools. First, locate the ignition coil on your engine. It is typically mounted on the engine block or the cylinder head. Once you have located the ignition coil, disconnect the electrical connector and remove the coil from the engine.
