Smog Checks

Smog Check and STAR Smog — we do both

OREC Imports is a California Bureau of Automotive Repair (BAR) STAR Smog Station, and we also perform regular California Smog Checks. Bring your DMV registration renewal notice — whichever type your car needs, we’ll take care of it.

We’re also CTC (Clean Truck Check) credentialed for the emissions side of the heavy-duty vehicle program. We do not service diesel engines.

Who needs a smog check in California

California requires a smog check at certain registration intervals for most vehicles. New residents have a window after registering a California vehicle to obtain a check (when one is required).

Common exceptions:

• Newer vehicles within their early renewal cycles
• Electric vehicles
• Motorcycles

Smog failure diagnosis and repair

If your vehicle hasn’t passed a smog check, we can look into the cause. Common contributors include:

• Oxygen sensor issues
• Catalytic converter condition
• Evaporative emissions (EVAP) system leaks
• EGR system issues
• Engine misfires affecting the catalyst

We’ll identify the cause, provide an estimate, and — after the repair — perform the retest.

What actually happens during the test

The test looks at what your vehicle is reporting about its own emissions systems and, depending on the vehicle and the program, what is coming out of the tailpipe. Modern cars monitor their emissions equipment continuously, and the readiness status of those monitors is part of what gets checked.

If you would like the longer plain-language version, we wrote one: how does a smog check work. And if you are trying to work out which type of test your renewal notice is asking for, the difference between Smog and STAR Smog covers it.

Every make we service

We smog Asian, domestic, and European vehicles alike. European service is a particular strength of ours, and it is worth knowing that European platforms often route emissions monitoring through more modules than average — which is one reason having manufacturer-spec diagnostic tools on hand matters when something needs looking into.

We do not service diesel engines.

Why a check engine light matters here

If your check engine light is on, that is directly relevant to a smog check, because the light means the vehicle is reporting a fault in a monitored system. Getting it scanned before you come in for the test is generally the more straightforward path.

We can scan it and tell you what the car is actually reporting. Our plain overview of what the check engine light really means explains why the light on its own does not tell you much.

We explain before we do

If your vehicle needs work to pass, you will hear what we found, what it does, and what your options are — in plain language, before anything is ordered. You decide how you would like to proceed.
