Why is my check engine light coming on? Unfortunately, when your vehicle's check engine light comes on, it doesn't tell you exactly what the problem is- only that you have one. It can be frustrating and worrisome, not knowing how big the problem is or what the cost of repair may be. Depending on the particular problem your vehicle has, the check engine light may be constant or it may be flashing. Whatever your situation, taking it to your trusted repair shop as soon as possible to find the problem can prevent any existing problems from getting worse. Especially if you notice a change in the performance of your vehicle.
What are the most common reasons for the check engine light to come on? Some of the most common reasons that your check engine light may be coming on are:
- Your spark plugs or the plug wires may need replacing.
- Mass Airflow sensor may need replacing.
- Your O2 sensor may need replacement.
- A missing or loose gas cap.
- Your catalytic converter may need to be replaced.
These are just a few examples of what your problem may be. It's best to bring your vehicle to our service center for complete diagnosis and repair. And peace of mind.
