OBD-II DTC Code Lookup

Search any diagnostic trouble code your scanner threw. Each page explains what the code means, its common causes, how serious it is, and the real vehicles that report it — with symptoms, repair costs, and fixes.

A DTC (Diagnostic Trouble Code) is the 5-character code an OBD-II scanner reads from your car's computer when the check-engine light comes on. The first letter tells you the system: P = powertrain (engine/transmission), B = body, C = chassis, U = network. A “P0” prefix means it's a generic code defined for every manufacturer; “P1” means it's maker-specific. A code points you at the affected system, not the exact broken part — the same code can have several causes, which is why Au7o pairs each code with the real failures owners actually find. No code yet? Start from what your car is doing instead. Browse the 877 codes below, or snap a photo of the problem and let Au7o diagnose it at au7o.io.
