It depends on California's emissions testing program, your registration ZIP code, and your vehicle's model year and fuel type. Some areas of California require testing, while others do not.

Prices vary by station and vehicle, but most emissions tests in Valencia fall within the typical range for California. Many stations list pricing by phone or on their website, and some offer coupons or discounts. Use the listings above to contact a station directly for current pricing.

Requirements depend on vehicle type (gasoline, diesel, hybrid, electric), model year, and weight, as well as where your vehicle is registered in California. In many states, fully electric vehicles are exempt, newer vehicles are temporarily exempt, and certain older or specialty vehicles may have different rules. Check the California state page for the latest 2025 requirements.

Most stations in Valencia ask you to bring your current registration or renewal notice, a valid photo ID, and proof of insurance if required by California. Make sure your vehicle is warmed up and the check engine light is off before you arrive.

If your vehicle fails, the station will provide a report showing the reason for failure (such as stored OBD-II codes or high tailpipe readings). In most programs, you must complete repairs and pass a retest before renewing your registration. Some states offer repair assistance, cost caps, or waivers. Details are listed on the California page in this directory.

In some states, certain vehicles are directed to specific station types (such as STAR or test-only centers).
