Frequently Asked Questions

We specialize in smog checks for vehicles model year 2000 and newer. These vehicles use the OBD-II (On-Board Diagnostics) system, which connects directly to your car's computer with no tailpipe emissions testing required at our facility.

Most OBD-II smog checks for vehicles model year 2000 and newer are completed in 30 minutes or less.

As a California state-licensed Smog Check Test & Repair station, we can diagnose why your vehicle failed—such as check engine light codes, incomplete readiness monitors, EVAP system leaks, or sensor faults—and perform the needed repairs. If your vehicle fails and we perform the necessary repairs, we will retest it at no additional charge.

Make sure your check engine light is off (an illuminated check engine light causes an automatic failure), ensure your car battery has not been recently disconnected (if it was, drive 50–100 miles so the OBD-II readiness monitors reset), and bring your DMV registration renewal notice with you.
