OBD Reference – Vehicles of Interest (Smog Check)

The following is a list of vehicles that may have issues with the OBD portion of the CA smog check (as of January 2023)

Gasoline and flex-fuel vehicles that are model-year 2000 and newer and diesel vehicles that are model-year 1998 and newer that have known pattern issues with the OBD test portion of an OIS inspection are provided below. Issues include, but are not limited to, no communication with the vehicle, incomplete readiness monitors, OBD test incompatibility, and false MIL illumination. In most cases, the OIS inspection is programmed to accommodate vehicles with a design anomaly. In other cases, the vehicle may require repair.

Whether you find your vehicle on this list or not and you are still having trouble passing a smog check here in Orange County, California, feel free to contact us for help: (714) 596-1019. For catalytic converter issues, please stop with your vehicle: 7722 Talbert Ave Ste B, HB, CA 92648.
