4 Common Reasons Your Car’s Engine Warning Light Is Turning On

Do you notice your car’s engine warning light flashing or turning on as you drive? When you see this indicator, it can mean a number of things, including an issue with the ignition, engine failure, and other concerns that require a visit to your local Kia dealer service center. 

4 Common Reasons Your Car’s Engine Warning Light is Turning On and When to Visit Your Kia Dealer

1. Catalytic Converter Problems

Your car’s catalytic converter reduces harmful emissions, and when it begins to fail, your vehicle won’t pass an emissions test, and you’ll notice a variety of signs, including a rotten odor, rattling sounds, and your car’s engine light. When you notice the check engine light is turning on, this may include more than the catalytic converter failure, which is often caused by a blown head gasket, a worn interior, and related damage, which requires urgent service.

2. Damaged or Loose Gas Cap

If the gas cap is loose or damaged, this can prevent the gas vapor from circulating in the tank system and may cause a leak. You’ll notice this happens when the gas cap is missing, as fuel will evaporate and cause your car’s check engine light to indicate a problem. While some gas caps are easily fixed by fighting their grip, it’s essential to check if there is further damage and determine if repairs or a replacement is needed.

If the gas cap is worn or faulty, it’s important to have this cap replaced immediately to prevent further loss of fuel and improve your vehicle’s performance.

3. Faulty or Dirty Airflow Sensor

Mass airflow sensors measure the amount of air that enters the engine, which is required to determine how much fuel your engine requires to run smoothly. Your car’s engine light may turn on when the MAS, or mass airflow sensor, requires cleaning due to grime, oil, and dirt build-up and may impact the air-to-fuel ratio. When this sensor doesn’t work properly, there is a significant reduction in fuel economy and your engine’s performance.

4. Spark Plugs are Worn

Your car’s spark plugs provide the ignition for air and fuel, giving power to your engine’s cylinders. When this system fails, and the spark plugs do not function properly, you may notice a check engine light and misfiring of your engine. When this occurs, the hydrocarbon emissions increase, which may cause damage and weaker performance.
