There’s nothing more frustrating than seeing your check engine light suddenly pop on while you’re driving around Kansas City. That little glowing light can mean anything from a loose gas cap to a serious engine issue. So, how do you know if it’s something you can fix yourself or if you should head straight to a trusted mechanic?
At Bret’s Autoworks, we help drivers figure that out every day. Here’s what you should know when your check engine light comes on — and what steps to take next.
Common Reasons Your Check Engine Light Comes On
1. Loose or Damaged Gas Cap
A loose, cracked, or missing gas cap is one of the most common reasons the check engine light comes on. It disrupts the fuel system pressure, which triggers the warning.
2. Faulty Oxygen Sensor
Your oxygen sensor monitors the air-to-fuel mix in your engine. When it malfunctions, it can reduce gas mileage and increase emissions; ignoring the issue can eventually damage your catalytic converter.
3. Worn Spark Plugs or Ignition Coils
If you’re noticing rough idling, misfires, or poor acceleration, your spark plugs or ignition coils might be to blame. These components are crucial to smooth engine operation.
4. Catalytic Converter Problems
The catalytic converter helps reduce harmful exhaust gases. If it fails, it not only hurts your car’s efficiency but can also lead to costly repairs.
5. Mass Airflow Sensor Issues
This sensor helps regulate the amount of fuel the engine needs based on the air intake. If it malfunctions, you may experience stalling, rough starts, or decreased fuel efficiency.
What Should You Do Next?
Check the Gas Cap First
Make sure it’s tight and undamaged. If that was the issue, the light may turn off after a few trips.
Watch for Other Symptoms
If you notice the engine running rough, stalling, or making unusual noises, it’s time to visit an auto repair shop immediately.
