Be Ready for Your Smog Check
These common indicators can affect results. If you notice any of the following, we can help diagnose issues before testing.
Common Issues That Impact Smog Tests
Check Engine Light On
Any active malfunction indicator lamp or stored trouble codes will cause an automatic failure.
Recently Disconnected Battery
OBD-II readiness monitors reset after battery disconnects or module resets and may need drive cycles to complete.
EVAP/Cap Issues
A loose or faulty gas cap and EVAP leaks are common reasons for failed readiness or stored codes.
Incomplete Readiness Monitors
Not enough drive time or specific driving conditions can keep monitors from setting, leading to a test rejection.
Modified Emissions Components
Altered or missing emissions equipment may prevent passing and will need to be addressed before testing.
Rough Running or Misfires
Misfires or poor engine performance can increase emissions and cause test failures.

Smog Check – Frequently Asked Questions
Helpful information for Bay Area drivers about the California Smog Check Program and our inspection process

In California, most vehicles need a smog inspection every two years for DMV registration renewal. Requirements can vary by model year, fuel type, and location. Your DMV renewal notice will indicate if a smog check is required.

Yes. An illuminated check engine light (or stored trouble codes) will cause an automatic failure. We recommend having any engine light diagnosed and repaired before testing.
3What should I do before coming in?
Make sure the battery hasn’t been recently disconnected and that you’ve driven your vehicle normally so OBD-II readiness monitors can set. Bring your DMV renewal notice or registration.
4How long does a smog check take?
Most inspections take 15–25 minutes. Times can vary based on vehicle condition and testing requirements.
5What if my vehicle doesn’t pass?
You’ll receive a detailed printout of results. We can perform diagnostics and provide an estimate for emissions-related repairs with your approval.
6Do you test all vehicle types?
We perform smog checks for most gasoline, hybrid, and light-duty diesel vehicles as required by the California Smog Check Program. Call ahead for specifics on your vehicle.
