The check engine light (CEL) can be a source of anxiety for any driver. It signals a problem, but doesn’t tell you what it is. A common question is, “Does Autozone Check Codes?” The answer is yes, AutoZone does check engine light codes for free with their Fix Finder service. This service helps pinpoint the cause of your CEL and provides potential solutions.

AutoZone’s Free Fix Finder Service: How Does it Work?
AutoZone’s Fix Finder service utilizes an OBD-II (On-Board Diagnostics) scanner to retrieve diagnostic trouble codes (DTCs) from your vehicle’s computer. These codes are like a secret language that reveals what’s going on under the hood.
When your CEL is on, simply visit your local AutoZone. A staff member will connect the scanner to your car’s OBD-II port, usually located under the dashboard. The scanner reads the codes, and the Fix Finder service translates them into a comprehensive report. This report includes:
- The specific trouble codes: These alphanumeric codes (e.g., P0420) pinpoint the system or component causing the issue.
- Potential causes of the codes: The report provides likely reasons for the triggered codes, based on a vast database of technician-verified fixes.
- Recommended solutions: Fix Finder suggests possible repair solutions, ranging from simple DIY fixes to more complex repairs requiring professional assistance.
- Suggested parts: The report may recommend specific parts needed for the repair, which you can conveniently purchase at AutoZone.
You’ll receive both printed and digital copies of this report, making it easy to reference and share with a mechanic if needed.
Common Reasons Your Check Engine Light Might Be On
While AutoZone’s Fix Finder service can diagnose the specific issue, understanding common causes of a CEL can be helpful:
Loose or Damaged Gas Cap
A loose or damaged gas cap can trigger the CEL because it allows fuel vapors to escape, affecting the evaporative emissions system.
Faulty Oxygen Sensor
Oxygen sensors monitor the amount of unburned oxygen in the exhaust. A malfunctioning sensor can lead to decreased fuel efficiency and increased emissions.
Engine Misfires
Misfires occur when the air-fuel mixture in a cylinder doesn’t ignite properly. Various issues, from worn spark plugs to faulty ignition coils, can cause misfires.
Mass Airflow Sensor (MAF) Problems
The MAF sensor measures the air entering the engine. A dirty or faulty MAF sensor can disrupt the air-fuel mixture, leading to poor performance.
Catalytic Converter Issues
The catalytic converter reduces harmful emissions. A failing converter can significantly impact your vehicle’s performance and emissions output.
What to Do After Getting Your Codes Checked at AutoZone
Once you have the Fix Finder report, you have several options:
- DIY Repair: If the issue is minor, such as a loose gas cap or a simple sensor replacement, you might be able to tackle the repair yourself. AutoZone offers a wide selection of parts and tools.
- Professional Repair: For more complex problems, it’s best to consult a qualified mechanic. AutoZone’s Shop Referral program can help you find trusted local repair shops.

AutoZone’s free Fix Finder service offers a convenient and valuable resource for understanding and addressing your check engine light concerns. So, if your CEL is illuminated, head to your nearest AutoZone to get those codes checked!
