New Smog Check Test

Smog Check Program’s Test Technology

Californians getting a STAR smog check today may notice that the traditional tailpipe test used for many years has been replaced by a quicker, computer-based test for gasoline-powered cars model-year 2000 and newer, and for most diesel vehicles that are model-year 1998 and newer. it’s easy to find them by using a STAR smog check.

This updated test uses the diagnostic capabilities of the vehicle’s computer system instead of the traditional tailpipe probe to measure the vehicle’s emissions. This On-Board Diagnostic (OBD) system gathers information and determines if the vehicle’s emission control systems are operating properly. A visual inspection of emission control components is still required as well..

The OBD only method of testing vehicles is the result of 2010 legislation (AB 2289-Eng) which is designed to improve the Smog Check Program and further reduce air pollution. The Smog Check program removes hundreds of tons of smog-forming pollutants from California’s air every day. That is why it is important to have your vehicle’s smog level checked at a STAR smog check station

Gasoline-powered vehicles model-year 1999 and older will continue to receive Smog Checks using a tailpipe probe as well as the OBD test.

Hybrid Vehicles

Hybrid vehicles have always been subject to Smog Check inspections. However, since their introduction to the California market in 2000, hybrid vehicles could not be properly tested using the traditional tailpipe test. During a traditional Smog Check, emissions are measured at low speeds or idle rates. At these lower speeds, however, hybrids switch to their electric motors, making it impossible to measure the emissions of their gasoline engines. The OBD only test now makes it possible to test these vehicles. It is important to remember that hybrids have internal combustion engines which generate pollution. it is important to have your vehicle’s smog level checked at a STAR smog check station

About Smog Check

The Smog Check Program is administered by the California Department of Consumer Affairs’ Bureau of Automotive Repair and is an important part of the State’s efforts to improve the quality of the air we breathe. The Smog Check Program removes hundreds of tons of smog-forming pollutants from California’s air every day. Smog Check inspections are designed to identify vehicles with excess emissions so they can be properly repaired to meet state and federal emissions standards.
