Kia Check Engine Light Flashing: Causes, Solutions, & What You Need to Know

A flashing check engine light is a cause for concern, as it indicates a serious problem that could potentially cause significant damage to your Kia. Ignoring the issue could result in costly repairs. This warning light is usually triggered by a severe engine misfire, which allows unburned fuel to accumulate in the exhaust system, potentially damaging the catalytic converter. Spark plugs are often the culprit behind engine misfires, and failing to address this issue can spread to other components, resulting in more expensive repairs. If you notice the check engine light flashing, it’s crucial to seek immediate assistance from our team of automotive experts at Cornerstone Kia.

Reasons Your Kia Engine Light Is Flashing

The check engine light in your Kia is often misunderstood and can display in various ways, such as “Check Engine” or a symbol of an engine. It illuminates in amber or red and is part of the onboard diagnostics system that controls and monitors various aspects of your vehicle’s performance. Your Kia engine light flashing could be caused by a number of issues within your Maple Grove vehicle:

1. A loose or damaged gas cap can cause fuel loss and trigger the check engine light; it seals the fuel system and prevents gas fumes from being released. Replace it if needed.
2. A bad mass airflow sensor can cause issues with engine efficiency, starting, and throttle position. Get it replaced if you experience such problems.
3. Improperly installed aftermarket parts and accessories like alarms and exhausts can trigger the check engine light, drain the battery, or prevent the car from starting. Ensure they are installed properly.
4. Neglected maintenance can cause damage to the catalytic converter, which can affect engine performance, fuel economy, and emissions. Get it repaired if needed.
5. The Oxygen sensor measures the oxygen in the exhaust system, and a faulty one can affect fuel economy, damage the catalytic converter, and cause emissions issues.
6. A low or dead car battery can prevent your car from starting and operating normally. Replace it as needed.
7. A vacuum leak in your Kia’s vacuum system can cause high RPM or surging, affecting emissions and engine performance. Check for cracks in vacuum hoses and get them replaced.
8. Worn spark plugs or plug wires can lead to poor engine performance, reduced power, and trouble starting. They can also cause damage to other engine parts, leading to more expensive repairs. Replace them as needed.

Kia Check Engine Light Reset

When the issue that caused the check engine light to turn on is resolved, the light on your Kia will usually turn itself off. For instance, if a loose gas cap was the cause, tightening it will turn off the light. Similarly, if your catalytic converter is malfunctioning due to excessive use, the light may come on after stop-and-go driving. Typically, the light should turn off after driving for 20-40 miles. However, if it remains on after that distance, you should bring your Kia to Cornerstone Kia to double-check and reset the code.
