Democratizing Auto Repair

We built OBD2HQ because we believe every car owner deserves to know exactly what's wrong with their vehicle before paying a mechanic.

Our Mission

To provide the world's most accurate, easily accessible, and comprehensive database of OBD-II diagnostic trouble codes.

Verified Data

Our data is aggregated from OEM repair manuals and verified by ASE-certified master technicians.

For Everyone

Whether you're a DIY enthusiast in your garage or a professional mechanic, our platform is built for you.

The Story

The automotive industry has traditionally kept diagnostic information locked behind expensive proprietary software subscriptions. Mechanics charge hundreds of dollars just to "plug in the scanner." We started OBD2HQ to break this monopoly.

By compiling data on over 48 global car manufacturers and analyzing over 10,000 specific Diagnostic Trouble Codes (DTCs), we've created a search engine specifically for your car's brain. From a simple loose gas cap (P0456) to a catastrophic hybrid battery failure (P0A80), you now have the knowledge to fix it faster.
