Description
Check engine light on? Look up OBD2 and DTC fault codes in seconds—even when you have no internet connection.
OBD2 Fault Codes stores its diagnostic reference database on your device. Read a code from any OBD2 scanner or code reader, enter it in the app, and get a clear explanation. The app is a reference tool and does not need to connect directly to your vehicle.
SEARCH AND BROWSE • Search by exact code, such as P0301 or P0420 • Search with everyday keywords such as misfire, oxygen, turbo or gas cap • Browse Powertrain (P), Body (B), Chassis (C) and Network (U) code families • Filter generic and manufacturer-specific codes by vehicle brand
CLEAR DIAGNOSTIC GUIDANCE • Plain-language code meanings • Common symptoms and likely causes • Suggested checks and practical fixes • Low, Medium, High or Critical severity ratings • Clear guidance about whether you should continue driving • Related codes from the same vehicle system
BUILT FOR QUICK REFERENCE • More than 1,400 fault-code entries • Core search and database features work offline • Save frequently used codes to Favorites • Code of the day for continued learning • Multiple interface and content languages • Light, dark and system themes • Accessible labels that do not rely on color alone
PRIVATE BY DESIGN • No account or registration required • Favorites, recent searches and theme settings remain on your device • No location, Bluetooth, camera, contacts or file-access permissions • The app contains ads; consent and ad privacy controls are provided where required
HOW TO USE 1. Read the diagnostic trouble code from your OBD2 scanner. 2. Type the code or a related keyword into Search. 3. Review its meaning, severity, symptoms, causes and suggested next steps.
No Bluetooth pairing or special adapter connection is required. OBD2 Fault Codes works as a companion reference for any scanner or code reader that displays standard diagnostic trouble codes.
IMPORTANT This app provides general diagnostic guidance, not a guaranteed diagnosis or repair authorization. Always confirm findings with a qualified technician and the service information for your vehicle before carrying out repairs. Manufacturer-specific definitions can differ from generic code meanings.
