How does the ignition coil work?

There are two sets of windings inside each ignition coil. The primary windings have hundreds of turns of heavy wire, while the secondary side contains thousands of turns of fine wire. Power supplied by the battery flows through the primary windings. When your car’s computer decides it’s time to fire that cylinder’s spark plug (or plugs), it cuts the current to the primary windings, causing the energy in them to collapse into the secondary windings. This multiplies the voltage, which is then sent to the spark plug in order to make it fire.

How often do ignition coils need to be replaced?

Some carmakers recommend replacing the ignition coils at scheduled intervals; this schedule should be followed to reduce the likelihood of failure. Some coils will last the lifetime of the vehicle, and other may only last 5,000 miles. Most will make it 60,000 miles or more.

How are ignition coil issues diagnosed?

For vehicles that use one coil per spark plug: If the engine misfire is only on one cylinder, the components for only that cylinder should be examined. If the coil is suspected, it will be tested and, if faulty, will be replaced. For older cars, with distributors: One coil will fire multiple spark plugs. If all these plugs are failing, the ignition coil will be suspected and tested.
