California’s OBD2 law is a critical component of the state’s efforts to maintain clean air. This regulation impacts vehicle owners and requires a functioning OBD2 system for emissions testing. Understanding the specifics of this law is essential for all California drivers.
What is the California OBD2 Law?
California has some of the strictest emissions regulations in the United States. The California OBD2 law mandates that all vehicles manufactured from 1996 onwards (and some 1995 models) must have a functioning On-Board Diagnostics II (OBD2) system. This system monitors emissions-related components and reports any malfunctions via diagnostic trouble codes (DTCs). During a smog check, technicians use an OBD2 scanner to access these codes and determine if a vehicle meets the state’s emissions standards. Failing to comply with the California OBD2 law can result in registration renewal issues.

A properly functioning OBD2 system not only helps ensure your car is environmentally friendly but also helps you avoid costly repairs down the road.
