- Creates the voltage necessary to activate the spark plugs
- For direct (coil-on-plug) ignition systems
- Replace when damaged or worn
The engine in your Nissan relies on the Direct Ignition Coils to start. Spark plugs require thousands of volts to create the correct spark, which is considerably more than the 12 volts your Nissan's battery is able to produce. Your ignition coils take the voltage from the battery, increase it, and forward it to the spark plugs. The spark plugs then have the power needed to start your vehicle. Without functioning Direct Ignition Coils, you can't operate your Nissan.
There are various types of ignition systems. A coil-on-plug ignition, also know as a direct ignition, has the ignition coils positioned on top of the spark plugs. In most modern cars, there is one Direct Ignition Coil for every spark plug, but some pair one coil with two spark plugs. Your engine size influences the number of spark plugs and Direct Ignition Coils your Nissan has. You can find information about your engine size in your owner's manual.
A Direct Ignition Coil usually has a lifespan of 100,000 miles, but this can vary based on your vehicle and driving habits. If your spark plugs are past the time for a replacement, it can strain your ignition coils and lead to quicker wear. When a Direct Ignition Coil is broken or stops working right, you can't repair it and will need a replacement. You could have a bad Direct Ignition Coil if your engine stalls, your car backfires, your car won't start, or your check engine light is on.
With the right knowledge and tools, it's possible to replace a Nissan Direct Ignition Coil on your own. However, you can always bring your vehicle to the closest service center to have trained professionals handle the replacement.
Your Nissan won't start without working Direct Ignition Coils. When you have a bad coil, you need to make certain you find the right replacement part. Shopping for genuine OEM parts can help you find the best fit for your vehicle.
