Understanding OBD2 Codes for Your Volvo S40 1998
OBD2 codes are standardized, but their specific meanings can sometimes vary slightly between manufacturers.

Common OBD2 Codes on a Volvo S40 1998
Several OBD2 codes are more common on older Volvo S40 models like the 1998 version. These can relate to the emissions system, such as oxygen sensor issues (e.g., P0130, P0135), or issues with the evaporative emissions control system (e.g., P0442). Misfires can also trigger codes like P0300 or more specific cylinder misfire codes (P0301, P0302, etc.).
