URD should provide the correct sensor, they know the difference between a wide band A/F sensor and a regular O2 sensor. That's why they list them all out seperately.

EDIT: as long as you gave them the correct info anyway. You can always call them to be sure.

but on there website you chose a product number based on whether you think its 49 state or cali spec. how would they be able to evaluate which car i actually have? they would be going based on which part# i tell them to send

i just look under my hood and there is a sticker right beneath my hood scoop that says the vehicle is in accordance with emission standards and californias... so guess what boys, i think i just figured out i have a CA 50 state 4runner. sweet... lol. now as i understand it, since i dont live in CA i dont have to be up to their standards... i only need one cat working, not both, but does that still mean the sensors are in different orders?

See my edit above.

Your state may not require those standards but your truck's ECU does or it will throw a code.

Actually, the model state law requires trucks to perform to the standard to which they were built. Many if not most states will not pass a 1996 and later vehicle with a CEL code. They don't use the tailpipe probe, they just plug into the ECU. And I believe there is a federal statute that says you can't modify the emissions performance from 'as-built'. This is to prevent modified truck showing up in California. So strictly speaking, you have to live with the Cali. standard. Then the question is how does NC implement and inspect for those laws--I have no idea. NJ runs the VIN and KNOWS it is Cali and wants it to do Cali standards if it was built Cali. NC may well be quite different.

In any case, that o2 sensor is useless to you. Go back to urd and get the A/F sensor for the Cali.

hey guys, got some good new... first off, credit to URD for running an awesome business that is in it for more than just profits, they want to educate and get you what you actually need. talked a guy in a tech and our conversation led us to find out i do have a 50 state 4runner so he swapped out the sensor(which was 2x as much). we also randomly talked about MAF cleaning and i told him i have a K&N air filter... more than likely the oil from it is clogging my sensors and MAF system. he advised i trash it and go get a regular toyota filter. he also said the DECK PLATE mod will actually yield better performance than the entire K&N intake system. so just some tidbits of info for you guys. im sure some of you already knew that but i found it shocking how much damage K&N does to our trucks. K&N buyers beware...

Good deal, did you talk to Gadget or Brian? I agree about the K&N air filter, I ditched mine a long time ago.

TheDurk

Yeah, I almost warned you about the price of the A/F sensor vs the o2. Now wait until you see the price for the two cats if you have to go there!
