(5) Notwithstanding the provisions of subsection (d)(4) above, warranty services or repairs shall be provided at all of a manufacturer's dealerships which are franchised to service the subject vehicles or engines. (6) The vehicle or engine owner shall not be charged for diagnostic labor which leads to the determination that a warranted part is defective, provided that such diagnostic work is performed at a warranty station. (7) The vehicle or engine manufacturer shall be liable for damages to other vehicle components proximately caused by a failure under warranty of any warranted part. (8) Throughout the vehicle or engine's warranty period defined in section (b)(2) and (b)(3), the vehicle or engine manufacturer shall maintain a supply of warranted parts sufficient to meet the expected demand for such parts. The lack of availability of such parts or the incompleteness of repairs within a reasonable time period, not to exceed 30 days from the time the vehicle or engine is initially presented to the warranty station for repair, shall constitute an emergency for purposes of section (d)(4) above. (9) Any replacement part may be used in the performance of any maintenance or repairs. Any replacement part designated by a manufacturer may be used in warranty repairs provided without charge to the vehicle owner. Such use shall not reduce the warranty obligations of the vehicle or engine manufacturer, except that the vehicle or engine manufacturer shall not be liable under this article for repair or replacement of any replacement part which is not a warranted part (except as provided under section (d)(7) above). (10) Any add-on or modified part exempted by the Air Resources Board from the prohibitions of Vehicle Code section 27156 may be used on a vehicle or engine. Such use, in and of itself, shall not be grounds for disallowing a warranty claim made in accordance with this article. The vehicle or engine manufacturer shall not be liable under this article to warrant failures of warranted parts caused by the use of such an add-on or modified part. (11) The Executive Officer may request and, in such case, the vehicle or engine manufacture shall provide, any documents which describe the manufacturer's

Do I have to go to the dealer to get my OBD II car fixed?

No. Properly trained and equipped independent shops are capable of utilizing the diagnostic information from the OBD II system and can make repairs just like dealers. In fact, several of the provisions incorporated in the OBD II regulation are intended to make it easier for independent shops to diagnose and repair vehicles accurately and in a cost-effective manner.

It should be noted, however, that California's emission warranty requires the vehicle manufacturer to repair under warranty any problem that the OBD II system detects if the vehicle is less than 3 years old and has less than 50,000 miles. Manufacturers only authorize their dealers to perform warranty work. Further, components which exceed a defined cost limit at the time the vehicle was produced (currently about $600) are covered for 7 years or 70,000 miles - this list of covered parts, which varies from car to car, should be listed in the owner's manual or accompanying warranty booklet that came with the vehicle.  Additionally, if you have purchased a vehicle that is certified by ARB as a partial zero emission vehicle (PZEV), any problem detected by the OBD II system is covered under warranty as long as the vehicle is less than 15 years old and has less than 150,000 miles. Starting with the 2018 model year, you can purchase a vehicle certified by ARB as a transitional zero emission vehicle (TZEV), which also will be covered under warranty for 15 years or 150,000 miles. The "energy storage device" (i.e., the hybrid battery) on PZEVs and TZEVs are covered under warranty for 10 years. A list of vehicles that are certified as PZEVs and TZEVs can be found at ARB's Drive Clean website (select vehicles with a Smog Rating of 9 to show PZEVs and TZEVs).

The 2009 list of parts covered under your emissions warranty.

List of parts covered under your emissions warranty:

Emission Control Parts

 1. Exhaust Gas Conversion Systems: oxygen sensor, thermal reactor, catalytic converter, dual-walled exhaust pipe

 2. Exhaust Gas Recirculation System: EGR valve, thermal vacuum switch, EGR solenoid, EGR spacer plate, EGR backpressure transducer, sensor and switches use to control EGR flow

 3. Evaporative Emission Control System: purge valve, fuel filler cap, purge solenoid, vapor storage canister and filter

 4. Positive Crankcase Ventilation (PCV) System: PCV valve, PCV solenoid

5. Air Injection System: Air pump, diverter, bypass, or gulp valve, reed valve, anti-backfire or deceleration valve

 6. Early Fuel Evaporative (EFE) System: EFE valve, thermal vacuum switch, heat riser valve

 7. Fuel Metering System: electronic control module (unit) or EFI air flow meter, computer command module or mixture control unit, deceleration controls, electronic choke, fuel injectors, fuel injection units and fuel altitude compensator sensor, bars or rails for EFI or TBI systems, mixture settings on sealed fuel mixture control solenoid, diaphragm or other systems, fuel metering components that achieve closed/other feedback control sensors/loop operation switches and valves

 8. Air Induction System: thermostatically controlled air cleaner, air box

9. Ignition Systems: electronic spark advance timing advance/retard systems, high energy electronic ignition

 10. Miscellaneous Parts: hoses, gaskets, brackets, clamps and other accessories used in the above systems 

Emission Related Parts These are examples of other parts of your vehicle which have a primary purpose other than emissions control but which nevertheless have significant effects on your vehicle’s emissions. If any of these parts fail to function or function improperly, your vehicle’s emissions may exceed federal standards. Therefore, when any of the parts of the following systems are defective in materials or workmanship and have failed in a way that would be likely to cause your vehicle’s emissions to exceed federal standards, they should be repaired or replaced under the emissions warranty:

1. Fuel Injection System: fuel distributor

 2. Air Induction System: turbocharger, intake manifold

 3. Exhaust System: exhaust manifold

4. Ignition System: distributor, spark plugs, ignition wires and coil 

5. Miscellaneous Parts: hoses, gaskets, brackets, clamps, and other accessories used in the above systems. 

 Major Emission Control Components? There are three specified major emission control components, covered for the first 8 years or 80,000 miles of vehicle use (whichever first occurs) on 1995 and newer vehicles: • Catalytic converters • The electronic emissions control unit or computer (ECU) • The onboard emissions diagnostic device or computer (OBD)

California Emissions Warranty Laws

California Emissions Warranty – Under the California Emissions Warranty, vehicles certified for sale in California, and those states like Vermont that have legally adopted California Emissions Standards and Warranty Provisions, have additional coverage beyond that required under Federal law. Under the California provisions, all emissions related parts are covered for 3 years or 50,000 miles*, and a vehicles specific list of more expensive emissions related parts is covered for 7 years or 70,000 miles*. In addition, the 8 year or 80,000 mile* coverage for the catalytic converter and engine control unit required by Federal law applies. Also, some models, designated as California Partial Zero Emission Vehicles (PZEV), have 15 year or 150,000 mile* emissions warranties covering essentially any component that causes the Check Engine Light to illuminate. These California Emissions Warranty provisions cover vehicles up to 14,000 pounds GVWR. * whichever comes first.
