What are Toyota Yaris OBD2 Codes?

OBD2, or On-Board Diagnostics II, is a standardized system in modern vehicles, including the Toyota Yaris, that allows for diagnosing and monitoring the various systems within your car.

These codes are essential for troubleshooting and maintaining your Yaris. For instance, a code like P0420 might indicate a problem with the catalytic converter, while P0171 could suggest a lean air/fuel mixture.
