Re: DTC P0128
Here is a snippet from Ford's site. The California warranty DOES cover other states provided the vehicle complies with PZEV standards and your state complies with California standards. I hope this information can help some people out. Be sure to see if your state is covered.
Vehicles Eligible for California Emission Warranty Coverage
California emission warranty coverage applies if your vehicles meets the following two requirements:
•Your vehicle is registered in California or other states adopting California emission and warranty regulations, * and
•Your vehicle is certified for sale in California as indicated on the vehicle emission control information label
* Other states adopting California emissions and warranty regulation:
•Passenger Car & Light-duty Trucks (up to 8,500 pounds GVWR) - California, Connecticut, Maine, Massachusetts, New Jersey, Oregon, Pennsylvania, Rhode Island, Vermont and Washington (NOTE: New York adopted California emission standards, but not the California Emissions Warranty; the Federal Emissions Control Warranty applies to all non-PZEV vehicles in New York)
•Medium-Duty Vehicles (over 8,500 pounds GVWR up to 14,000 pounds GVWR) - California, Connecticut, Maine, Massachusetts, Oregon, Rhode Island, Vermont, and Washington
•Light Heavy-Duty Diesel Engine Vehicles (over 14,000 pounds GVWR up to 19,500 pounds GVWR) - California, Maine, and Pennsylvania.
