1998 Subaru Legacy OBD2 Code Reader: Understanding Your Car’s Language

A 1998 Subaru Legacy, like all vehicles manufactured after 1996, uses an OBD2 system to monitor its engine and emissions performance. When the check engine light illuminates on your dashboard, it’s a signal that your car’s computer has detected a potential issue and stored a corresponding trouble code. That’s where an OBD2 code reader comes in – it’s your key to understanding what your car is trying to tell you.

Common OBD2 Codes on a 1998 Subaru Legacy

Here are some common OBD2 codes you might encounter on your 1998 Subaru Legacy:
