Check engine light keeps reappearing with different codes

Well, multiple diagnostic trouble codes (DTC's) can be set, and many can cause the check engine light to illuminate. Some codes set as a result of other codes present. And some codes have nothing to do with other codes. All codes should be interpreted by a trained technician so proper troubleshooting can occur. If you'd like, you could post some codes here so we can feed back impressions about them.
