Your check engine light is part of your car’s onboard diagnostic system (OBD). It monitors performance and emissions, alerting you to potential issues like:

- Catalytic converter issues
- Loose or damaged gas caps
Ignoring this light can result in decreased fuel efficiency, reduced engine performance, and even significant damage to critical components.

Common Causes of a Check Engine Light
Sensor Malfunctions
Sensors like the oxygen sensor or mass airflow sensor monitor key functions. If they fail, your car may experience rough idling, reduced power, or higher emissions.
Catalytic Converter Issues
The catalytic converter reduces harmful emissions. A damaged converter can trigger the check engine light and lead to reduced fuel economy.
Ignition System Problems
Worn-out spark plugs or ignition coils can cause misfires, impacting engine performance and triggering the warning light.
Loose or Faulty Gas Cap
A loose or damaged gas cap can cause vapor leaks, triggering an emissions warning. This is often one of the easiest and quickest fixes.
If you’re unsure of the issue, contact us today for expert diagnostics.
