Check Engine Light Diagnostics serving Charlotte, NC and surrounding areas

What Does the Check Engine Light Mean?

The check engine light is part of your vehicle’s onboard diagnostic system (OBD). It monitors various components, including the engine, transmission, and emissions systems. When the system detects an issue, it triggers the check engine light to alert you. While the light can indicate minor issues, such as a loose gas cap, it may also signal more serious problems like misfiring cylinders, faulty oxygen sensors, or catalytic converter failure. Ignoring the light can lead to reduced performance, increased fuel consumption, and costly repairs.

Common Issues Behind the Check Engine Light

There are many potential reasons your check engine light might turn on. Some of the most common include:

• Faulty Oxygen Sensors: Can affect fuel efficiency and emissions.
• Loose or Damaged Gas Caps: May trigger an emissions-related warning.
• Malfunctioning Mass Airflow Sensors: Impact engine performance and fuel economy.
• Spark Plug or Ignition Coil Problems: Lead to misfires and reduced power.
• Catalytic Converter Failures: Affect emissions and overall vehicle performance.

Regardless of the cause, Mechanic On Duty is equipped to handle the diagnosis and repair with precision and care.
