DTC Library

Use this page to quickly define your retrieved DTCs.

Our DTC database contains definitions for both Generic (B0, B2, C0, C2, P0, P2) and Manufacturer Specific (B1, C1, P1) DTCs as well as OBD1 codes.

Because OBD2 is an evolving system, new codes and definitions will be added as the system matures. Our database is constantly being updated to include more Manufacturer Specific (P1) code definitions. Our database currently contains code definitions for 43 different vehicle makes.

Always consult the vehicle's service manual for code definitions not included here or continue to check this site as more code definitions are added.
