If your car won’t pass smog, you have three clear options: repair it if costs remain below $1,000, apply for state repair assistance up to $1,200, or sell it when repair costs surpass the car’s value. Repairs typically range from $1,500 to $3,000 for major failures like high NOx. Cars above 100,000 miles rarely justify these costs.
Failing smog tests prevents vehicle registration, restricts selling privately, and makes driving legally impossible after the grace period. Choosing the correct resolution helps avoid unnecessary spending.
Resolving Common Smog Test Failures
Typical failures involve high emissions: hydrocarbons (HC), nitrogen oxides (NOx), or carbon monoxide (CO). Check-engine lights automatically fail smog tests.
Hydrocarbon (HC) Failures
High HC emissions indicate unburned fuel issues, commonly fixed with spark plug replacements ($50–$150), ignition coil repairs ($100–$400), vacuum leak sealing ($100–$300), or fuel injector cleaning ($200–$800).
Limits vary by model year: pre-1990 vehicles allow up to 220ppm, 1990s vehicles around 130ppm, and newer models below 80ppm.
Nitrogen Oxide (NOx) Failures
NOx issues suggest overheating combustion. Repairs often involve EGR valve replacements ($150–$350), catalytic converters ($500–$2,500), or carbon buildup cleaning ($200–$500).
High NOx repairs quickly become expensive. Consider selling if costs exceed the car’s worth.
Carbon Monoxide (CO) Failures
High CO levels signal excessive fuel. Common fixes include replacing oxygen sensors ($100–$300), cleaning airflow sensors ($50–$200), or replacing fuel pressure regulators ($150–$350).
Resolve CO issues quickly to avoid damaging the catalytic converter.
How to Address Gross Polluter Status
Gross polluters exceed emission limits by over 200%, requiring repairs at state-certified STAR stations. Average repair costs reach $2,000–$4,000.
Repairing a Gross Polluter
STAR stations charge 30–50% more for repairs. Consider retirement programs offering $1,000–$1,500 instead. Retirement permanently resolves gross polluter status.
California Retirement Program
California offers $1,500 cash for vehicles labeled as gross polluters. Eligibility requires two years of continuous registration and recent driving. Retirement usually provides more value than costly repairs.
Using State Assistance Programs
The CAP program provides financial assistance for smog repairs or retirement. Income limits apply at 225% of the federal poverty level.
CAP Repair Assistance
CAP covers up to $1,200 in repairs at STAR stations. Participants pay a small copay ($20–$200). Eligibility includes continuous registration, insurance, and initial smog test failure.
CAP Retirement Option
CAP retirement offers $1,500 for qualified vehicles, often exceeding the car’s repair value. This allows quick resolution without risking unsuccessful repairs.
Resolving Visual and Functional Test Failures
Smog tests require original stock components. Aftermarket modifications cause failures. Gas cap issues or EVAP leaks commonly cause functional test failures.
Visual Inspection Issues
Aftermarket air intakes and modified exhaust systems fail inspections. Returning to stock parts costs around $100–$1,500, depending on modifications.
Functional Test Solutions
Gas cap replacements ($15–$30) and EVAP system repairs ($300–$1,500) typically resolve functional issues. OBD2 communication problems ($200–$800) must also be fixed promptly.
Obtaining Temporary Smog Waivers
Temporary waivers provide short-term resolution after documented repairs at STAR stations. Spending $650 or more qualifies vehicles for a two-year waiver.
Economic Hardship Waivers
Income-qualified individuals may qualify for reduced or waived spending requirements. Veterans, disabled persons, seniors, and single parents receive priority consideration.
When Selling Makes Sense
Selling is smart when repair estimates exceed half the vehicle’s value or for catalytic converter repairs on older vehicles. Selling resolves issues permanently and prevents ongoing expenses.

County Differences in Smog Requirements
Smog rules differ by county: Enhanced areas require stringent testing, Basic areas simpler tests, and some rural counties offer exemptions.
Enhanced Areas
Major cities like Los Angeles and San Francisco use rigorous dyno testing. Compliance requires meeting stricter standards and comprehensive visual inspections.
Basic and Rural Areas
Basic areas offer simpler, less costly tests. Rural areas sometimes exempt testing altogether, allowing easier registration renewals.
