The ignition system is a critical part of any gasoline-powered vehicle. Without a functioning ignition system, your car simply won't start. One important component of the ignition system is the ignition coil.
In this blog post, we'll discuss what an ignition coil is, when it should be replaced, and some symptoms of faulty ignition coils.
What is an ignition coil?
An ignition coil is a device that converts the low voltage from the battery into the high voltage needed to create an electric spark in the spark plugs. The spark plugs then ignite the fuel in the engine, allowing the car to start and run. There are two types of ignition coils: coil-on-plug and distributor-based. Coil-on-plug ignition systems have a separate coil for each cylinder, while distributor-based ignition systems have a single coil that fires multiple spark plugs at once.
When should an ignition coil be replaced?
Ignition coils can last for many years, but they can also fail unexpectedly. It's important to replace a faulty ignition coil as soon as possible to avoid damaging other components in the ignition system. If you experience any of the symptoms listed below, you should have your ignition coils inspected and replaced if necessary:
Engine misfires: When the ignition coil fails, it can cause the engine to misfire. This means that one or more cylinders are not firing properly, which can lead to a rough idle, reduced power, and increased fuel consumption.
Hard starting: If the ignition coil is failing, it can make it difficult to start the engine. You may need to turn the key multiple times or pump the gas pedal to get the engine to start. Stalling: A failing ignition coil can cause the engine to stall while you're driving. This can be dangerous if it happens in traffic, so it's important to get it fixed as soon as possible.
Check engine light: If the ignition coil is failing, it can trigger the check engine light. This is because the engine control module (ECM) monitors the performance of the ignition system and will detect any issues.
Reduced fuel economy: When the ignition coil is failing, it can cause the engine to run inefficiently. This can lead to reduced fuel economy, which means you'll have to fill up more often.
Conclusion The ignition coil is an important component of the ignition system, and it's essential to keep it in good working order. If you experience any of the symptoms listed above, you should have your ignition coils inspected and replaced if necessary. By taking care of your ignition system, you can keep your car running smoothly and avoid costly repairs down the road
