If you are a proud owner of a 1999 Honda Civic, you already know that it is a reliable vehicle that can last for years. However, just like any other car, your Honda Civic may develop issues with its ignition system. To troubleshoot these problems, you need a wiring diagram that illustrates how the ignition system works. In this article, we will provide you with a comprehensive guide on the 1999 Honda Civic ignition wiring diagram. Read on to find out more.
Understanding the Ignition System
Before we dive into the wiring diagram, let’s first understand how the ignition system works in the 1999 Honda Civic. The ignition system’s main purpose is to ignite the fuel-air mixture in the engine’s cylinders, which is what makes the engine run. The ignition system is made up of various components, including the battery, ignition switch, distributor, spark plugs, and ignition coil.
The battery produces the electrical energy required to start the engine. When you turn the ignition key, it sends an electrical signal to the ignition switch, which then activates the starter motor. The starter motor turns the engine over, and a combination of fuel and air is sucked into the cylinders. To ignite this mixture, the spark plugs use an electric spark, which is produced by the ignition coil. The distributor distributes this spark to each of the spark plugs at the right time.
