Note: This list is focused on Powertrain (P-codes) OBD2 error codes. There are other categories of OBD2 codes including Body (B-codes), Chassis (C-codes), and Network/Communication (U-codes). While this list provides a strong starting point, always consult a professional mechanic for accurate diagnosis and repair of your vehicle’s issues. Using an OBD2 scanner can help you retrieve these codes, but understanding the underlying problems often requires expert knowledge and specialized tools.
