O2 sensors deleted. Will it pass emissions
I know this question has probably been asked before, but i searched and could not find an answer. If the post cat O2s are deleted out of the PCM, will the car pass emissions and will the emissions place be able to see that they've been deleted?

Here in TN I only know of half a handful of people that failed from not having cats. They're supposed to do a visual but I'm pretty sure the big black lady puts the mirror under the car just to follow protocol. Computer says everything is fine and I'm on my way.

We don't even have a visual here in IL. No mirror, no engine bay check, no sniffer.....nobody looks or cares. Just a quick OBD scan and you're on your way.

Thanks guys. I'm in Illinois. I had the PCM reprogrammed to remove the rear O2s. The car has aftermarket cats installed, so if they do check, they will see that there are cats on the car.

In Houston we have the OBD2 plug in test but no one looks under the hood or under the car. I passed once with totally bald back tires. Out of the city areas there is not even the plug in test.

We are OBD scan only in IL; there is no sniff, there is no visual, and cars 1995 and older are exempt.
They won't even look.

Baahaaaa, they fill out my sticker before they even see the car The last time I took the camaro up there, all the mechanics cleared out of the bays to come out and look at the car. The lady took my paperwork inside and filled out the stuff so I could stay outside and shoot the ****.

Edit: Just noticed the P0103 code, if that is current then it will cause you to fail, regardless of the readiness status.

What you have to do is put all the codes associated with those 3 tests to 3 - No Error Reported. Since there are so many of them, I kinda do like a big sweep of many of the emissions codes and it eventually makes 3 of the 4 tests ready then I go in for the inspection. Right after I go back to the original tune.
And you'll have to do the same for the MAF code also.
