Smog check and repair in Carlsbad, CA: Honda Odyssey with the hood up on the smog test ramp in our bay

We are a STAR-certified smog station and a full repair shop in the same building. That matters most when a car does not pass. At a test-only station, a failed car has to go somewhere else to be repaired and then come back. Here, the same shop that tested the car can find the cause, repair it, and test it again. For the current smog price, see our coupon page.

  • ASE-certified technicians
  • Written estimate before any work
  • BAR licensed station #311178
  • Walk-ins welcome

Signs your car may need work before smog

Check engine light on
The engine computer has stored a fault. Check engine light problems are a common reason cars do not pass.
Battery recently replaced or disconnected, or codes recently cleared
The car's self-tests (readiness monitors) need to run again through normal driving before the car is ready.
Rough idle or misfire
Unburned fuel raises emissions and can damage the catalytic converter.
Exhaust leak or loud exhaust
A leak can affect readings and set codes.
Smell of fuel
A leak in the fuel or evaporative system.
Failed a smog check elsewhere
Bring the report. We start the diagnosis from what it shows.

How smog testing and smog repair work here

If the car passes, you are done. If it does not, the repair follows the same steps as any job in our shop.

  1. Test

    We run the smog inspection on our STAR-certified equipment.

  2. Explain and estimate

    If the car does not pass, we explain the failure in plain terms, diagnose the cause, and give you a written estimate for the repair.

  3. You approve

    You decide what we repair.

  4. Repair

    We repair the cause in our shop: ignition, fuel, sensors, vacuum leaks, evaporative leaks, exhaust, or catalytic converter, depending on what failed.

  5. Retest

    Once the repair is done and the car's readiness monitors are complete, we test it again here. Our $30 smog retest covers one retest within 30 days of the paid, failed inspection.

Nothing is repaired without your OK.

California's Bureau of Automotive Repair requires a written estimate and your authorization before work begins, and if we find something new partway through, we stop and ask before going further.

Frequently asked questions

What does STAR-certified mean for me?

Our station meets the Bureau of Automotive Repair's STAR program standards. If your renewal notice says your vehicle must be tested at a STAR station, we can test it.

What happens if my car fails?

We explain why, diagnose the cause, and give you a written estimate. You decide whether we repair it. After the repair, we retest the car here.

Why should I not clear my check engine codes right before a smog check?

Clearing codes resets the car's readiness monitors. The car then needs normal driving for those self-tests to complete before it can be tested.

How much is a smog check?

See our coupon page for the current price.

Can I walk in for a smog check?

Walk-ins welcome. Booking online holds a time for you.
