Smog Check Program’s Updated Test Technology
Californians getting Smog Checks today may notice that the traditional tailpipe test used for many years has been replaced by a quicker, computer-based test for gasoline-powered cars model-year 2000 and newer, and for most diesel vehicles that are model-year 1998 and newer.
Engine changes continue to present problems and challenges to car owners and technicians. Our recommendation is to rebuild and reinstall the original engine, transmission, and emission control configuration.
When rebuilding an engine, it must be rebuilt to the original equipment specifications. However, if you do decide to change the engine, these guidelines must be observed to ensure that the vehicle will be eligible for smog certification or registration.
The Bureau of Automotive Repair (BAR) licenses and contracts with several different types of Smog Check stations to meet the needs of consumers and their vehicles. Stations are required to post a sign so that consumers can easily identify them. Look for the station’s official sign when selecting a station to perform your next Smog Check.
