How do I tell if my '00 Tacoma is Cali or not?
Is there any easy way? It's harder to look up on the internet than you would think. I've been google searching and searching here. I guess most people know. I'm on the east coast, but with all the military moving out here, it's possible my truck was a california truck originally.

That's the info I was looking for. Thanks... I guess I have a Cali truck.
Does this mean I have an anemic version? I've got some CEL codes I'm chasing down and I'm pretty sure I'm going to be changing the O2 sensor. I know that means I'll have to spend more for the California one.
What are the big differences?

He's asking if it's a California emissions model. Take a look underneath and if it has 2 catalytic converters it's CA model.Either way, mine's a California emissions truck. I pulled the upstream O2 sensor and it's the higher dollar one like the California emission trucks have. I've got two cats too. I also found a sticker under the hood that says it meets all federal and California emission requirements, I suppose that's a dead giveaway.
What are the substantial differences then? Is there any difference in performance? If so, is there anything I can unCalifornia on it to gain any performance back?

It was either 2000 or 2001 that Toyota started making all their vehicles 50 states legal IE Calif compliant
One way to know for sure is to hook up a OBD-II scanner and under one of the options you can ask the ECM if its a FED compliant or CARB compliant.
As far performance losses the only loss is the restriction due to the extra cat converter in line. You can remove that cat but the computer will constantly throw a P0420 Catalyst efficiency low code.
To avoid this you can install a rear O2 sensor simulator from URD.com and it will make the ECM see a perfect reading from the sensor and think it is working at 100% efficiency.
I live in Texas and have a 01 4runner and have been there and done that with dealing with the rear O2 sensor and the P0420 code. Even if your not after better performance, after about 90K miles your cat will get weak enough to throw a P0420 all the time.
You can either throw ALLOT of money at the dealer and get a new OEM cat or you can get a O2 simulator and save allot of money.
Don't waste your money on the high flow aftermarket cats, they are not nearly as efficient as the OEM cats and will give you a P0420 code all the time.

Why are aftermarket cats bad? I raced in the import scene back in '95 and for 8 years I never saw a problem with good quality aftermarket cats which cost a bit over $100 vs spending 8x that for an OEM cat.
I have a Cali truck but fortunatly no issues with the cats here and performance wise I don't think there's really a measurable difference in performance since when I raced my truck at the truck event here in denver at the strip I was just as slow as the other 4Runners I saw run.

look on the sticker under the hood. if it says something like 'approved for 2009 model year federal emissions standards and approved for 2009 model year california standards.' then its a cali.

Please try searching for this topic.
I have a multiple page thread of my troubles with the dual cat CEL codes.
If you a have two cats you have a California emission-spec rig, if you have one you do not.
Simple as that.

I did search for quite a while. Maybe I'm not up to speed on all the yota lingo, but I couldn't find what I wanted. Care to link me to your thread? I'd like to read it. I'll search for your screen name too, but if it's an easy find for you, please share.

Dual Cat Thread
I usually use the Advanced Search feature.
For example, for this thread search, search for my username and select "Threads started by this user" then search for "Dual Cat" as a keyword.
Hope it helps.

"dual cat" were the key words I was missing. Thanks.
I'm a moderator on a couple other sites. I'm plenty familiar with how to use the search function, I just don't always know the best key words to look for. Thanks for your help.

Read it all. I'll order a new A/F sensor here shortly. Thanks again.
How's the O2 simulator treating you if you're still running it. I'm going to ditch at least my rear cat eventually.

The VIN starting with a 4 has nothing to do with it being a CA spec model. The first digit in a VIN tells the place it was manufactered. If it starts with a J (no Taco VIN should begin with that, only 4runners) then it was manufactured in Japan. All Tacos are made in Fremont, California. Your Taco is not CA spec model.
