* 7 years/70,000 miles, whichever comes first, California emission coverage.

** 8 years/80,000 miles, whichever comes first, Federal emission coverage. (Also applies to California Certified Light Duty and Medium Duty Vehicles.)

Parts specified in your maintenance schedule as requiring scheduled replacement are covered up to their first replacement interval or the applicable emission warranty coverage period, whichever comes first. If failure of one of these parts results in failure of another part, both will be covered under the Emission Control System warranties.

If equipped, items marked with an asterisk are covered by the California long-term emission control system Defects Warranty for 7 years/70,000 miles. (For example, if one of these parts causes a smog check failure after the 3 year/50,000 mile performance warranty has expired, the part is still covered for 7 years/70,000 miles.)

For detailed information concerning specific parts covered by these emission control system warranties, ask your dealer.

I’m happy you’re healing wonderfully, kerrlakelover!

Unfortunately, I don’t have access to the information you’re seeking about the NOX sensor. However, I can look into the warranty and possible cost assistance with this. I’ll send you a private message of the information I’ll need to get looking into this for you.
