Corona Norco Smog Inspection


Corona Norco Smog Check offers smog testing for license renewal, required every other year depending on the type and age of the vehicle. Smog inspections are also done after a change of ownership, and for residents who are new to the state of California and are obtaining CA plates for the first time. Our testing process is run by the Bureau of Automotive Repair’s California Smog Program.

We sponsor the Professional Firefighters Benevolent Fund. With over 30 years of experience, you can trust our inspectors to provide accurate results.

Here are just some of the things you should know about smog testing in California. For more information, visit the state’s DMV website.

What a Smog Test Looks For

There are three sections in a California smog test and (unless your vehicle is exempt from all or part of the smog test), your car must pass all three sections. The emission inspection is done by a smog machine, also known as an exhaust gas analyzer. During this step of the inspection, this machine looks for the presence of Nitrous Oxide, Carbon Monoxide, and Hydrocarbons, which are the three chemicals that contribute to the production of smog. The next two sections are visual and functional. A smog technician works with the machines to look for any issues with these two inspection areas.

Some parts of California have an especially high smog pollution. In these areas, cars are now required to undergo an enhanced version of the smog test, which requires your vehicle to drive on a machine called a dynamometer. The smog machine collects samples of the car’s emission from the tailpipe.
