What Does the Check Engine Light Mean?
The check engine light indicates that the vehicle’s computer has detected a problem within the engine or emissions system. The issue could range from a loose gas cap to a malfunctioning sensor or more serious mechanical trouble. The light may stay on steadily or flash, with a flashing light commonly signaling a more urgent problem that requires immediate attention.

What Are Common Causes of a Check Engine Light?
Many different issues can trigger the check engine light. Common causes include faulty oxygen sensors, worn spark plugs, failing ignition coils, mass airflow sensor problems, or emissions-related issues. 

How Is the Problem Diagnosed?
Diagnosing a check engine light involves scanning the vehicle’s computer system for diagnostic trouble codes. These codes help technicians identify which system or component is malfunctioning. Additional testing and inspections may then be needed to confirm the exact cause and determine the proper repair, ensuring the issue is resolved rather than temporarily cleared.

Can Regular Maintenance Prevent Check Engine Light Issues?
Routine maintenance plays a major role in preventing check engine light problems. Regular tune-ups and prompt attention to minor issues can keep sensors and engine components functioning properly. Addressing small problems early reduces the likelihood of unexpected warning lights and costlier repairs.
