Here's what you should do:
1. Get a code read: The "Check Engine" light indicates a problem with the engine's emissions system. The first step is to get a code read. This can be done at:
* A mechanic: They'll have the tools to connect to your car's computer and read the diagnostic trouble codes (DTCs).
* Auto parts store: Many auto parts stores offer free code reading services.
2. Research the code: Once you have the code, you can research its meaning online. Many resources are available to explain what the code means and potential solutions.
3. Address the issue: The specific problem will determine the solution. It could be a simple fix like a loose gas cap, or a more complex issue requiring professional repair.
Possible causes of the engine light:
* Loose gas cap: A common and easy fix.
* Oxygen sensor malfunction: A sensor that measures oxygen levels in the exhaust.
* Catalytic converter issue: A component that converts harmful exhaust gases.
* Spark plug or ignition coil problem: Responsible for igniting the fuel mixture.
* Mass airflow sensor issue: Measures the amount of air entering the engine.
* Evaporative emissions system leak: Controls fuel vapors.
Important Note: Always trust a qualified mechanic to diagnose and repair your vehicle. Attempting to fix an engine issue without proper knowledge can be dangerous and may worsen the problem.
