Smog Check Overview



The Bureau of Automotive Repair (BAR) is charged in law with implementation and oversight of the Smog Check Program.

• BAR licenses stations and inspectors who perform Smog Check Inspections and/or repairs

• BAR certifies inspection equipment, and oversees industry compliance with Smog Check Program laws and regulations

• BAR, with help from Air Resources Board (ARB), establishes emissions standards for vehicles

• BAR, with help from ARB, analyzes Smog Check Program compliance with state and federal performance requirements

Smog Check Overview



The Smog Check Program is a major component of the State of California’s ongoing efforts to reduce air pollution caused by emissions from cars and trucks.

According to the California Air Resources Board (ARB), the Program is responsible for removing approximately 400 tons of smog-forming pollutants from California’s air every day.

Why Smog Check?


Smog Check Overview



• The word smog is derived from two words: smoke and fog. Smog is produced by vehicular and industrial emissions

• Photochemical Smog is the result of the chemical reaction of sunlight, Nitrogen Oxides (NOₓ) and Volatile Organic Compounds (VOCs) in the atmosphere

• This chemical reaction results in poor air quality

What is Smog?


Smog Check Overview



Ground Level Ozone (O3) is a by-product of the reaction between Hydrocarbons (HC), Nitrogen Oxides (NOₓ), and sunlight. Both HC and NOₓ are components of vehicle exhaust.

Ozone can:• Irritate the respiratory system

• Worsen the effects of asthma and bronchitis

• Reduce the body’s ability to fight off bacterial infections in the respiratory system

• Inflame and damage the lining of the lungs and reduce lung function

• Aggravate chronic lung diseases, such as emphysema

What is Ozone (O3)


Smog Check Overview



• Despite significant success in improving air quality in California, air pollution continues to be a serious public health problem

• Health-based ambient air quality standards, which include standards for pollutants such as ozone and particulate matter, are set by the Air Resources Board

• Long-term exposure to these pollutants may lead to serious health effects, such as cancer, even when the exposure level is low

• Both air pollutants and toxic air contaminants are measured statewide to monitor the success of programs, such as the Smog Check Program, in improving air quality

Health Effects of Smog


Smog Check Overview



Sources of California Air Pollution

Data compiled from the most recent California Air Resources Board's Emissions Inventory report.

** Residential fuel combustion, farming operations, construction, road dust, wind-blown dust, fires, waste burning, utility equipment and other miscellaneous processes.


Smog Check Overview



Hydrocarbons (HC): HC emissions from a vehicle are unburned fuel. High levels of HC emissions may indicate incomplete fuel combustion. Low engine compression also can produce high HC tailpipe emissions. The Smog Check Program measures HC in parts per million (PPM).

Motor Vehicle Emissions

Carbon Monoxide (CO): CO is a colorless, odorless gas that can be fatal. CO emissions are often the by-product of an overly rich fuel mixture. The Smog Check Program measures CO as a percent (%) of vehicle exhaust volume.


Smog Check Overview



Nitrogen Oxide (NOₓ) is an odorless gas that contributes to smog. Excessive combustion chamber temperatures are the primary cause of NOx, which could be caused by:• Lean air/fuel mixture• Advanced ignition timing• Carbon buildup in the combustion chamber• Malfunctioning Exhaust Gas Recirculation (EGR)• Malfunctioning engine cooling system

The Smog Check Program measures NOx in parts per million (PPM).

Vehicles Subject to the Smog Check Program



Smog Check Program AreasThis section covers the three geographic areas of the Smog Check Program:

• Enhanced

• Basic

• Change of Ownership

These areas determine when a Smog Check is required and the type of inspection required.



Enhanced and Basic Areas Biennially (every other year) as part of registration renewal for

vehicles that are more than six model-years old Upon change of ownership of vehicles that are more than four

model-years old• Exemption does not apply to diesel powered vehicles

Upon initial registration of a vehicle in California

Change of Ownership Areas Upon change of ownership of vehicles that are more than four

model-years old• Exemption does not apply to diesel powered vehicles

Upon initial registration of a vehicle in California

When is a Smog Check Required?



To become a licensed Smog Check Inspector, the candidate must:

• Meet minimum experience requirements

• Meet minimum training requirements

• Pass a BAR licensing examination

Licensed Inspector Requirements



To become a licensed Smog Check Station, the facility must:

• Be registered with BAR as an Automotive Repair Dealer (ARD)

• Meet minimum equipment and facility requirements

• Employ licensed inspectors

• Retain service and repair records for three years

Licensed Station Requirements



• Test-Only: These licensed stations can only test and certify vehicles; they are prohibited by law from performing any diagnostics or repairs

• Test-and-Repair: These licensed stations can perform both inspections and repairs on most vehicles• Some licensed test and repair stations (STAR) have met certain

performance standards to be eligible to test and certify all vehicles. They also perform repair assistance services under BAR’s Consumer Assistance Program (CAP)

Smog Check Overview


Vehicle Verification

The Licensed Smog Check Inspector:

• Verifies that the vehicle matches the DMV renewal form

• Enters a confidential access code into the Emissions Inspection System (EIS)

• Scans the DMV renewal form into the EIS • Manual entry is allowed if the DMV renewal form is not

available• Enters vehicle information as required following EIS prompts


Smog Check Overview


1. Visual InspectionLicensed inspector carefully examines the vehicle’s emissions control systems to ensure they are connected and have not been tampered

2. Emissions Test Licensed inspector uses the EIS to measure a sample of the exhaust emissions produced by the vehicle

3. Functional Test Licensed inspector tests the operation of certain emissions control systems to ensure they are working properly

Smog Check Inspection Elements


Smog Check Overview


Overview of Smog Check ProceduresEnter Access Code Licensed inspector enters a confidential access code to begin the test.

Enter Vehicle Information Licensed inspector scans/manually enters vehicle license, VIN, year, make, model, engine, etc.

Visual Test PCV TAC EVAP CAT EGR Fuel Injection/Carburetion Air Injection O2 Sensor Vacuum Lines, Sensors/Switches Other ECS Visible Smoke

• Licensed inspector determines if required emissions control systems are present and properly connected as originally installed. Some vehicles have aftermarket parts that require an ARB Executive Order (EO) number

• Use of component locator manuals and service manuals may be required to properly inspect the vehicle

• Visible Smoke: Licensed inspector must check for visible smoke from the engine crankcase and tailpipe

Functional Test EGR (only for TSI) Ignition Timing Low Pressure Fuel Evaporative Test

(LPFET) Fuel Cap Onboard Diagnostic II/MIL

• Licensed inspector performs various functional tests applicable to the vehicle• LPFET is required on all 1995 and older gasoline powered vehicles• OBD II test is required on most 1996 and newer gasoline powered vehicles and 1998 and newer

diesel vehicles• Fuel Cap test is required on all 1999 and older gasoline powered vehicles

Emissions Test Acceleration Simulation Mode (ASM)

or Two-Speed-Idle (TSI)

• ASM tests, using a dynamometer, are required on most gasoline powered vehicles (includes CNG, LPG, Flex Fuel) registered in Enhanced Areas

• Exceptions are made for vehicles equipped with Full-Time AWD or non-disengaging traction control, motorhomes, and heavy-duty vehicles exceeding 5,000 pounds (unloaded) on the driven axle. In these cases, a TSI test is required to prevent damage to the dynamometer

• TSI tests are required on all gasoline powered vehicles registered in Basic or Change of Ownership Areas


Smog Check Overview


• EIS determines if the vehicle passes or fails the overall inspection

• EIS transmits test results to BAR’s central database

• EIS prints out test results on a Vehicle Inspection Report (VIR)

• Licensed inspector signs and dates the VIR under penalty of perjury and provides a copy to the consumer

• Passing test results are transmitted to DMV for vehicle registration
