2. Catalytic Converter Problems: Issues with the catalytic converter, which helps control emissions, can also cause the light to come on.
3. Engine Misfires: If the engine is experiencing misfires due to faulty spark plugs, ignition coils, or other engine-related problems, the check engine light may be activated.
4. Faulty Sensors or Modules: Various sensors and modules within the engine management system can fail or malfunction, resulting in the check engine light illumination.
5. Emissions System Issues: Any problems or discrepancies in the emissions control system, such as leaks or malfunctioning components, can trigger the check engine light.
