Solving the Mystery: Understanding Check Engine Light and Ignition Coil Failure

When to Worry About Your Check Engine Light: Tips for Diagnosing Ignition Coil Failure

Don’t Ignore Your Check Engine Light

Is the check engine light on your dashboard board illuminated? Vehicle owners need to understand the check engine light better. Sometimes, the fix is as simple as changing the gas cap, but in others, it’s more detailed and complicated. For example, it might require an ignition coil replacement to turn off the check engine light.

The Connection Between Check Engine Light and Ignition Coil Failure

Your vehicle has a computer system that controls its operation. The Onboard Diagnostic System, or OBD, is continually moderate, monitoring the entrance performance. When a problem is identified within your car’s emission system, it triggers the appropriate light on your dashboard to let you know there’s an issue. Now, an ignition coil takes the low volt voltage from the car battery and changes it to the volts needed to create the spark that ignites the fuel/air mixture. And now that we have computer-controlled systems, your vehicle comes equipped with either one ignition coil for each spark plug or every two spark plugs. When an ignition coil goes wrong, the fuel-air mixture won’t ignite, and the engine will most likely misfire. If there’s no spark, the raw fuel in your engine can damage the cylinder or the catalytic converter. To prevent or minimize problems with the ignition coil, you can do preventative maintenance on your vehicle. Get tune-ups recommended by the manufacturer and change the spark plugs and wires to protect the ignition coil. If the check engine light has come on, check it out immediately. If you need to replace ignition coils, you want to have them all replaced simultaneously, even if only one is bad.
