What's different with California Emission System on V10?
 

I am looking at getting another Superduty crew cab 4x4 2008-2010 with a V10 gasser. I have seen several window stickers that said the truck came with the California Emission System. What does this system add to the truck that does not come with trucks made for the other states? How does this affect gas mileage and drivability?

Depending on the year, and GVWR, it may or may not mean you have an extra O2 sensor after the catalytic converter, and/or an EGR valve.

It won't mean squat in terms of power, but an EGR valve may actually IMPROVE gas mileage. Or not.

I think you will find that just about every truck sold out west will have Cal. emissions.

The biggest difference is Ford paid a form of tax to CARB for permission to sell it in CA.

I'm not sure there are ANY physical differences any more.

On the '99's, there was the second post-cat O2 sensor, but I suspect all may be getting it now. It is actually handy to have this second O2 so the PCM can monitor the function of the catalytic converter and warn you if it is failing.

And I am not sure about any of them getting EGR's anymore. Although EGR's are great for part throttle performance, fuel economy, and emissions, they also tend to be a relatively low reliability device compared to most systems on modern cars. They do have a tendency to get dirty or fail within 200K miles.... which is considered low reliability these days! Do away with it, do away with warranty repairs and customer complaints.

I can't go into it right now because of lack of time, but ... it's more complicated than that.

my 03 is a ex-CALI truck from new and it has no EGR... doesnt look like it was ever deleted either..

but it does have a post CAT O2 sensor thou.

I live in Wisconsin and am currently looking at a used 03 SD with a V10 that was originally purchased new in California. I have been told by a reputable mechanic, who owns and operates a large diesel shop, to stay away from it, if it has a Cali emissions sticker under the hood. Neither of us had time to discuss why, but all he said was "nothing but trouble." He is a previous owner of a V10 and states that he would buy another one without hesitation, absolutely loved it. What is so bad with California emmisions that he would consider it poison?

sounds like bunk to me..

there is certainly no real world difference between a non-CALI and a CALI emissions truck, to make that statement..

My 2003 F-350 was specifically built for me by the Ford when I was a resident of New York State during the time of order . Today I checked the stickers , it says California Emission compliant as of 2003 . If there were different versions , why do I get a truck with California emission delivered to me while I am residing in NYS .

(This statement is for 2003 models , I have no knowledge of other year models ) .

I did not see a classic EGR pipe sticking out of exhaust pipe on the side of the V10 that I have ( but not 100% sure , at least not obvious to me ) .

I did not get underneath the truck today , but I remember seeing some O2 sensor (s) after the cat too ( I will double check them at next opportunity ).

The other day I responded someone about O2 sensor wiring terminals at PCM . The 2003 V10-wiring diagram I got from library shows two O2 sensors for non california and a 3rd one for California compliant models ( a bit puzzling to me , may be the wiring diagram was a generic one ) .

IIRC, there was a point in the early 2000s when it became easier to make things 50 state instead of 49 state and then CA. This also was/is driven by several states adopting CA standards. Since the difference is fairly small, it makes sense just to build to one standard.

Probably does not affect all models, but would explain the NY vehicle meeting CA standards.

IMO, we should have Fed standards only. And to go further, we should reconcile standards world wide, especially European vs. US diesel standards. It's just nuts we can't get the high mpg oil burners here, and the differences in standards are simply crazy making, adding cost without any measurable benefit overall.

And we could get the high MPG diesel European cars! The problem is our Whack job EPA, especially now that we have our "Historic" president. The Euros are way to smart to give up the mpg they get to adopt our idiot diesel regs.

New York is one of the "Green states". That's CA, NY, MA, ME, and VT I think.

My '96 t-bird had to have the CA emissions. Same with my '97 Cougar. Johnny Langton ran the differences on my '97 Cougar between the fed and CA calibration, and the only difference was a slight change in the EGR opening/closing/timing.

However, my 2001 V10 did NOT have California Emissions, but that doesn't mean much if the truck met California emissions at the time.

I am purchasing a 2008 F250 V10 out of Arizona and the Emission sticker under the hood says "Not for California compliance" I checked with the Fed. Emission Board of Automotive" to see if I can register this truck in Ca. and They said that as long as the truck has more than 7500 miles and it is used that I can register this truck in Ca.
