The check engine light is an indicator on your vehicle’s dashboard that alerts you to a potential issue with the engine or emissions system. When this light comes on, it is a signal that your Harley’s onboard diagnostic system has detected a problem that needs attention. While it can be tempting to ignore the light and continue riding, it is important to address the issue as soon as possible to prevent further damage to your motorcycle.
Some common causes of the check engine light coming on in Harley motorcycles include issues with the exhaust system, faulty spark plugs, or a loose gas cap.

One common cause of the check engine light coming on in a Harley is a loose gas cap. When the gas cap is not secured properly, it can cause the fuel system to lose pressure, triggering the check engine light. Checking to ensure the gas cap is tightly closed can often resolve this issue.
Another possible reason for the check engine light to illuminate is a faulty oxygen sensor. The oxygen sensor plays a crucial role in monitoring the amount of oxygen in the exhaust gases. If it malfunctions, it can lead to improper air-fuel mixture, resulting in poor engine performance and triggering the check engine light.
Furthermore, a failing catalytic converter can also be a culprit behind the check engine light coming on. The catalytic converter is responsible for converting harmful pollutants into less harmful emissions before they exit the vehicle. If it is not functioning correctly, it can trigger the check engine light and lead to increased emissions.
Importance of Addressing the Issue

Ignoring the warning may lead to further damage to your motorcycle’s engine, resulting in costly repairs down the line.

As the light indicates a potential issue with the engine or emissions system, continuing to ride without addressing the problem can lead to decreased performance and increased fuel consumption. This can not only impact the overall riding experience but also cost you more money in the long run.
By using diagnostic tools to determine the cause of the check engine light and taking the necessary steps to resolve the issue, you can ensure that your Harley continues to run smoothly and efficiently.
