Deciphering the Secrets of Your 2004 Pacifica OBD2 Code
Your 2004 Pacifica, like all modern vehicles, uses an On-Board Diagnostics II (OBD2) system to monitor various systems and components.

Common 2004 Pacifica OBD2 Codes and Their Meanings
Some codes are more common than others in the 2004 Pacifica. These can range from relatively minor issues like a loose gas cap (P0442) to more serious problems with the emissions system (P0420), transmission (P0700), or engine (P0300).
