Hi Christopher. Most of the time, OBD-II error codes don’t erase on their own. When a repair has been completed, the ECU needs to be told that it has been done, which resets and clear the old codes and allows the ECU to recycle to check if the issue has been resolved. This is completed by a professional mechanic through a check engine light inspection.
