Here are the gory details:

• Federal Emissions Warranty – Under the Federal Emissions Warranty, all emissions related parts are covered for 2 years or 24,000 miles*, with the catalytic converter, onboard emissions diagnostic device or computer (OBD), and engine control unit (the ECU or computer) covered for 8 years or 80,000 miles*. These Federal Emissions Warranty provisions cover light-duty vehicles up to 8500 pounds Gross Vehicle Weight Rating (GVWR).

• California Emissions Warranty – Under the California Emissions Warranty, vehicles certified for sale in California, and those states (e.g., Vermont) that have adopted California Emissions Standards by law, have additional coverage beyond that required under Federal law. Under the California Emissions Warranty, all emissions related parts are covered for 3 years or 50,000 miles*, and a vehicle-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, onboard emissions diagnostic device, and engine control unit required by Federal law also applies. Also, some 2003 and later models, certified as California Partial Zero Emission Vehicles (PZEV), have 15 year or 150,000 mile* emissions warranties essentially covering 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

However, be aware that some manufacturers have voluntarily extended their emissions control warranties for certain models and certain parts to 14- or 15-years and 150,000 miles (whichever comes first).
