Convert 2001 2.7 to non-California emissions standard

have a 2001 2.7 california emmisions. whats does all have to be switched to convert to a non-California emissions ?????

 

Remove one of the cats I guess? But it will throw a CEL/code unless you get an o2 simulator or other method to trick the ecu.

Don't really see why it would be worth the trouble to make it 48 state legal vs 50?

Just straight pipe it at that point if that's what the goal is

 

Is there a reason you want to do that?

Most people end up taking their trucks out of CA spec because a CAT gets stolen or goes bad, and because they are expensive to replace, they opt not to. If you do that though, you gotta do something to trick the ECU into thinking the cats are working correctly. The light would be on... Which people get around by just removing it. But when the CEL is on, the truck doesn't run as well as it could. All in all, it's just not that great of an idea.

I do know that some people do an EGR removal on the 2.7. I think you'd need a good reason to do that though.

 

i am in canada with a california truck. just wondering what parts all are specific cal emissions where most second hand vechiles here are not cal emissions. just wondering where most of my emisiion sensors say cali emissions.
had a/f sensor go few months back,now having high idle issues, cheap hand held tester says nothing but cat flashing

 

Unless the cat is bad and needs to replaced, there's no need to replace it. I don't think a California emissions system restricts power in a Tacoma compared to a federal 49-state system. If you don't live in California, then that means you can put in a 49-state cat and not have to worry about passing an emissions test. What's weird is that I think the California emissions system was only required for the vehicle to be sold new in California. If someone bought a vehicle new in Florida, Oklahoma, or somewhere that only doesn't have the draconian California emisisons standards but doesn't require testing period, then moved to California, then that vehicle would still pass smog in California with the 49-state system. Diesel vehicles older than a certain year are not only exempt from smog testing in California, but not even required to have a cat if they came from the factory without one.

I'm not sure if you can get away with installing a 49-state cat in California when the original fails, but if you don't live in that car-nazi nanny state, I wouldn't worry about. Some people just delete the cat entirely when it fails, if they don't live in a state that requires emissions testing. I live in Pennsylvania, which is nowhere near as unreasonable as California, but still has emissions testing 25 out of 67 counties. I could do away with the muffler and still pass emissions, but I would not be able to delete the cat...

 

I would just make sure you use your vin to pull up the part numbers you need, for instance in getting a new O2 sensor you'll want to make sure it's the right one for your model as it might be different for 48 state legal or Canada emissions ones, I'm not sure.

But if you order a part that's tied to your VIN then you won't have to worry

www.partsouq.com is a great website for part numbers, just plug in your VIN and find the diagram that has the part listed that you need.

what code are you getting exactly, is it a cat inefficiency code or a code for the front o2 sensor specifically?

 

i only have a cheap, cheap tester, just gives codes and has a list on the side of emissions sensors, which also has cat, and it is the only thing flashing,

 

not sure how or if there is a test for the cat
?

 

I have a California emissions truck sold in CA and that has never left CA. I only have the one catalytic converter, I know some other trucks have 2.

 

This is worded horrendously.

The truck was built to CA emissions standards. And would be subject to those standards if it still resided in CA.

You don’t want to switch to non CA standards. You want it to be street legal in Canada. I bet a nice cookie that CA standards are either equivalent or stricter than your Great White North regulations.

You need to search for emissions standards in your province, then fix your truck to meet those standards.

And either get a better tool to test with, or take it to a shop.

 

don't quote me on it but I think the dual cats started in 2000 for all Tacomas

around when Toyota just started making all of them 50 state compliant

 

Yeah that makes sense. To be honest with you I don’t know what makes a truck cali compliant. Maybe different cats? I think all trucks had EGR at this point.

 

Would a 2010 with the 2.7L have dual cats; I know have two oxygen sensors in the exhaust, but I'm pretty sure I only have one cat...?

 

Go pop a look under your truck.

 

I don't know what the 2nd gen setups are like. I thought they had some kind of smaller cat or something up in the header then the bigger cat after that, not sure.

 

I was just under it earlier this month when my mechanic had it on the lift to replace the U-joints in the driveshaft. I know that there is a cat located right next to where the Toyota dealer found the hole in my old frame, and there is some sort of box-shaped emissions afterburner thing under the bed, but I'm sure it only has one cat...? Why why would an inline-4 with a single exhaust need two catalytic converters?

 

Because California CARB and the Federal EPA standards were being more stringent and required this. Why do you think a huge 8.0l Cadillac v8 from the 70’s only made like 100 HP? Lol

 

I know about cars from the 1970s and 1980s, but OBD2 was mandated in all passenger vehicles for MY1996, with heavy-duty trucks (2500/3500) being subjected to that in 1998-1999; I once met a guy with a gas-powered 1997 F250 that was OBD1...

Anyway, I think that California-specific emissions systems became all but obsolete in 1996, with the introduction of OBD2. This is the emissions control sticker under the hood of my 2010 Taco...

 

I have a 2001 and it has two cats....it was built in California and and spent its life there until a few years ago. It's a Texas truck now.

I think, but not 100% sure, that the cats for California have more of the precious metals in them to help scrub out more of the bad shit?

I have the P0420 code on mine now (again) so if I need to replace the front cat (sensors before and after that one only) I can use a OEM style cat, according to Magnaflow, and not the California model...which is about 50% more expensive. The "OEM" version should keep the codes away. I don't see any reason I would need the second rear one. Anyone have opinions or experience in this example?

 

Bruh, you’re fawk eh. Just fix the shit and take it in.

Canada is land of the not free, like ca.
