Fast and Reliable Check Engine Light Diagnostics

Your check engine light is your car’s way of telling you it needs attention. Whether it’s a simple fix like a loose gas cap or a more complex mechanical issue, addressing it early can save you from expensive repairs and keep your vehicle performing at its best.

Drivers across Michigan trust The Detroit Garage for accurate diagnostics and honest repairs. Our skilled technicians use advanced tools to quickly identify the problem and deliver reliable solutions to get you back on the road in no time.

What is a Check Engine Light Diagnostic?

A check engine light diagnostic taps into your vehicle’s onboard diagnostics system to uncover the cause behind the warning light. The system produces trouble codes that point to specific issues, like a faulty sensor or an emissions problem. By analyzing these codes, technicians can accurately identify the root cause and recommend the appropriate fix.

By analyzing these codes, our technicians can identify the root cause and recommend the right fix — catching minor issues before they escalate into costly problems, like a failed catalytic converter. With advanced tools and expertise, diagnostics help keep 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 point to potential issues.
  • Interpreting the Codes: Each code offers valuable insight, helping us pinpoint the underlying problem.
  • Visual Inspection: Based on the codes, we inspect critical components to verify the diagnosis and assess their condition.
  • Additional Testing: When necessary, we conduct further tests to confirm the issue and help ensure an accurate diagnosis.

Advanced Equipment for Accurate Results

We use advanced tools and technologies, including professional-grade scan tools, electrical testing devices and the latest diagnostic software, to deliver accurate diagnostics. This enables us to handle everything from minor fixes to complex engine or transmission problems.

With a careful approach and top-tier equipment, we help ensure your vehicle receives the precise diagnosis it needs to remain safe and dependable.

Common Reasons the Check Engine Light Comes On

Your check engine light can signal a range of issues, and knowing what’s behind it can save you time, money and hassle. Here are a few common causes:

Loose Gas Cap

A loose or damaged gas cap can create a fuel system leak, triggering the check engine light as the system detects an issue with fuel vapor containment.

Sensor Malfunctions

Faulty sensors, like the oxygen sensor or mass airflow sensor, can affect engine performance, leading to poor acceleration, reduced fuel efficiency or rough idling.

Ignition System Issues

Worn spark plugs or failing ignition coils can cause engine misfires, resulting in reduced power and performance.

Catalytic Converter and Emissions Problems

A failing catalytic converter impacts emissions control, increasing exhaust pollutants and reducing overall engine efficiency.

Our technicians are experts at identifying and fixing the issues behind your check engine light with accuracy and care. Here’s how we address common problems:

  • Oxygen Sensor and Catalytic Converter Repairs: Faulty sensors and damaged catalytic converters are common culprits. We replace these components as needed to keep your engine running efficiently and compliant with emissions standards.
