Ignition Coil Overview

The ignition coil is an essential component of your vehicle's ignition system. It serves the vital function of transforming the battery's low voltage into the thousands of volts necessary to create an electric spark in the spark plugs, which then ignites the fuel. Without a properly working coil, your car might experience poor performance, a rough idle, or fail to start entirely.

How It Functions

The coil works on the principle of electromagnetic induction. It has two sets of windings - primary and secondary - wrapped around an iron core. When current flows through the primary winding, it creates a magnetic field. Interrupting this current causes the magnetic field to collapse, inducing a high voltage in the secondary winding, which is then delivered to the spark plug.

Signs of a Faulty Coil

If the ignition coil is broken, several issues may occur. Your vehicle might misfire, stall, or lose power. The check engine light might turn on, and you could also notice a significant decrease in fuel efficiency. In the worst-case scenario, your vehicle might not start at all, leaving you stranded. Regular maintenance and timely replacement of the ignition coil are crucial for uninterrupted vehicle performance.
