Understanding Your Check Engine Light
Your check engine light signals that your vehicle's computer has detected a problem. Ignoring it can lead to costly repairs or reduced performance. Common reasons your light may illuminate include:
- Faulty oxygen sensors
- Loose or damaged gas cap
- Catalytic converter issues
- Mass airflow sensor problems
- Spark plug or ignition coil failures
- Transmission-related concerns
Addressing the problem early saves you time and money. A small issue today can become a major expense tomorrow.
