Emissions question

So I talked to Emissions place today, even if you haven't passed your emission test you can just register your car to a new area without emissions and you'll automatically be exempt from emissions.

I did however call Jessie white office and asked if you can register your car under a P.O. Box number and you can not. It has to be a physical address.

I did also get advice from the Jessie white office. Told me to look at state farm insurance.

Well after looking at state farm insurance a car that is ten years or older can qualify for "antique auto insurance"

I talked to the state farm representative told him my whole story and he was able to get my car insured. The only thing is I have to drive under 2000 or less miles a year. Also you have to fill out he government paper work to be exempt from emissions and show your proof of insurance with its known limitations.
I don't how much its going to cost me yet they are shooting me a quote later.

It is my understanding that he turned off my rear o2 sensors, I'm sure he asked me and I said 'yes'. At the time, I was running some off-road pipes. With the o2 sensors turned off, you would pass emissions because the car isn't throwing any codes.

But now they are testing to see if the o2 sensors are turned off. If they are turned off, it is an automatic fail. That is what I believe is causing me to fail. I just need Tim to turn them back on so that I can pass emissions.


You are doing it wrong and wasting your time. You do not drive the car more than 3K miles per year anymore. Just get a different policy and do the Show Car Exemption.

Just curious from a budgeting stance, but how much did the show car policy cost compared to the regular version for the car? Is it that big a jump in cost? I know it all depends on policy settings before and after, but generally speaking, what is it?

I am not sure because when I bought my car it went straight on the Show Car policy from Hagerty. I pay $400 for full coverage for the entire year.

I don't believe this. My mom registered her car to a P.O. box last year. Hassle free.

I don't think I've driven the car more than 2k for the last two years combined. That should change now that I've got everything back in working order.

The other reason I want to get it emissions friendly is in case it sells. I'd feel a lot better telling the new buyer that there isn't any emission issues with the car. If I don't pass with the revised tune, then maybe I'll just do the Show Car via insurance.

not lol about the performance, but not sure if any state workers review the show cars applications, if they do, they may lol at the general aspect of explorer being show car.



I can see your point and kind of agree. Surprisingly, there are some young fellas out there that put all sorts of chrome shit and wagon wheels on these trucks and parade them around like they are the next 427 Shelby Cobra. Oh well, I guess anything can be a show car, really, even if most would think it a bit odd. ;) Mine's more of a "go" car...

i'm going to be applying, have a 2013 so not sure when the first emission notice will come by my rear O2's are tuned out, not sure if they are only detecting ford or GM too now.

GM / HPT perform this in a different way than Ford / SCT does. Basically Ford / SCT actually turns them off per se in the tune which is why they don't report a MIL but also report as "not ready" in the tests. Since you can only have one minor system check as "not ready" and still pass in IL, having both off will fail. In HPT for GM you keep the MIL/SES enabled for them but set the error mode to "3-no error reported". This is what allows the GM cars to still report their O2 sensors test as completed but not throw a MIL error for it. The key in the GM tuning is to make sure that the SES box is still checked to allow the SES to occur and then set error mode to 3 so that it just never shows up. If it is done differently then you won't pass emissions.

What I usually do to make absolutely sure that I pass emissions with my G8 is just do an "emissions tune" that I temporarily load for the day of the test that literally has ALL DTC's in the tune set to enabled and error mode 3. This forces it to go to an immediate pass status right when the car is started. Normally this would take a few seconds if the car is tuned normally, but so far the shops haven't been educated enough to catch it.

This is all stuff that you can verify on a normal code scanner that can also see if your internal diagnostic emissions tests have been done. As long as you have no MIL reported and all but one or less of the minor tests that are supportable are set to "ready" status then you should pass in IL.

worded. absolutely. perfectly.

although fwiw, i have passed without the box checked, and with it set to error mode 3, and the guy who needed his cruze tuned like this just passed last month too this way.
