Non-california emission O2 sensor for other 49 states

Because the states have the same laws regarding emission certification. So New York just uses the Calif. certification for New York vehicles. How do I know this?? I was a the holder of an unlimited Calif. Smog inspection license.

Because the cat that is approved for California is "finer tuned" than the other 49 states. California emission standards are the toughest in the country, so many engine and emission parts are made just for those standards.

I will suggest if you ever drive it to California, unless you comply with their rules it won't be legal. However if you're a legal resident in another state, abide by their rules u should be ok. Again this is not legal advice, it's a suggestion.

There are two type of emission classes.

Federal and California emissions.

Look under the hood for the emission class sticker.
Smog check station's machine in CA are programmed to handle both types.

You do not need to change anything before the inspection.

==== Side notes: You should check the service record for the last Catalytic converter,O2 sensors and EGR valve change.
Service interval for
Catalytic ~180,000 miles O2 ~150,000 miles EGR ~160,000 miles


If you can locate the last smog test (even from out of state) Check for the
CO NOx

if you have a SOHC engine 92 stealth from California the number will be ;MD153355
SOHC Federal emission ECU number will be ;MD153354 .
DOHC , AWD , Turbo Cali emissions ; MD159965
DOHC , AWD ,Turbo federal emmissions ;MD159966
DOHC non-turbo Calif ;MD159962
DOHC non-turbo fed. ; MD159963

yes, as long as the O2 sensor screw tightly and the clip (plug in match) dont recomend any cutting or rigging the wire it self. all O2 sensors has built with the same concept.

not sure with a nissan, but with GM, the ECM's were different with Calif. emmisions
