Your check engine light is your car’s signal that something needs attention. From a loose gas cap to more serious engine or emissions issues, tackling the problem early can help you avoid costly repairs and keep your vehicle running smoothly.

Drivers across North Carolina turn to Atlantic Tire & Service for accurate diagnostics and trustworthy repairs. Using advanced tools, our experienced technicians quickly pinpoint the issue and provide dependable solutions to get you back on the road fast.

What is a Check Engine Light Diagnostic?

A check engine light diagnostic uses your vehicle’s onboard system to uncover the cause of the warning light. The system generates trouble codes that point to specific issues, such as a faulty sensor or emissions problem. By analyzing these codes, technicians can pinpoint the root cause and recommend the right solution.

Diagnostics can catch small problems, like a loose gas cap, before they escalate into costly repairs, such as a failed catalytic converter. With advanced tools and expertise, this process keeps your vehicle safe, efficient and ready for the road.

How Our Diagnostics Testing Works

Our skilled technicians use a detailed, step-by-step approach to uncover the cause of your check engine light:

  • Scanning for Trouble Codes: We connect to your vehicle’s onboard diagnostics system to retrieve diagnostic trouble codes (DTCs) that indicate potential issues.
  • Interpreting the Codes: Each code provides valuable insight, helping us pinpoint the underlying problem.
  • Visual Inspection: Based on the codes, we inspect key components to verify the diagnosis and assess their condition.
  • Additional Testing: When necessary, we perform further tests to confirm the issue and ensure an accurate diagnosis.

Advanced Equipment for Precise Results

We use professional-grade scan tools, electrical testing devices and the latest diagnostic software to accurately identify issues with your vehicle. This technology allows us to handle everything from small repairs to more complex engine or transmission problems.
By combining advanced equipment with a focused approach, we deliver precise diagnostics to keep your vehicle safe and running reliably.

Common Reasons the Check Engine Light Comes On

Check engine light warnings can mean different things. Knowing the cause can save you time, money and unnecessary stress. Here are a few common reasons:

Loose Gas Cap

A loose or damaged gas cap can cause a fuel system leak, triggering the check engine light when the system detects a problem with fuel vapor containment.

Sensor Malfunctions

Faulty sensors, such as the oxygen sensor or mass airflow sensor, can disrupt engine performance, causing poor acceleration, lower fuel efficiency or rough idling.

Ignition System Problems

Worn spark plugs or failing ignition coils can lead to engine misfires, reducing power and overall performance.

Catalytic Converter and Emissions Problems

A failing catalytic converter affects emissions control, increasing exhaust pollutants and decreasing engine efficiency.

Solutions for Check Engine Light Issues

Our technicians specialize in accurately diagnosing and resolving the issues behind your check engine light. Here’s how we handle common problems:

  • Oxygen Sensor and Catalytic Converter Repairs: Faulty sensors and failing catalytic converters are frequent causes. We replace these components as needed to keep your engine efficient and emissions-compliant.
