Need to pass inspection in Texas Hello All,
Went in for an inspection today with my vehicle, just moved to Texas. I had a check engine light for a clutch sensor or something, so i cleared the code before I went in. It came back with 3 not ready's. Evap not ready, O2 sensr not ready, and O2 htr not ready.
I have deleted my O2's Front and rear (running full OL Speed density), I'm wondering once my vehicle reactives all of my monitors if I should pass. I have NO O2's hooked up, and I don't want to fail again when I go back in to get reinspected. Its a 2001 Pontiac. I'm not completely sure if the O2's are "tuned" out, so if anyone can check and see, that would be great. I just need to know what i need to do to pass, so I can get my vehicle inspected!
Thanks!

If I knew how the inspection computer read my computer, I might be able to set No Mil's for everthing and it should be good. But, like I said, I don't know how it reads my computer. Still need to call SNL.

If I have no O2's hooked up (no front or rear because I'm running OLSD) will it still fail the test for the O2's after it resets the emissions checks?? Or since its Open loop will it pass?.

Well, I guess what I need to know is if my car is in Open Loop (where it is not monitoring the mv's from the O2's) will I pass. Does the inspection machine just read codes or does it actually monitor the MV's coming from the O2's? My car never throws a DTC for the O2's even though i dont' have them all disabled because it never runs in Closed loop.

From what I saw, the machine they were using had rollers. I'm assuming that since the O2's came back Not ready, they didn't bother to run it on the rollers, and they said that the machine has to "sniff" the O2's. Guess I threw 40 bucks down the drain. Know of a place where I can get this done with only an OBDII check? I'm near Watauga, North Richland Hills area. PM if you must.

I appreciate the information, but its not helping, what i need to know is:
If I have NO O2's hooked up, will the "readiness" monitors be set, or will they ALWAYS read "not ready"?
Thanks a bunch.

I took a look at your tune, it looks as if whoever made the cal was expecting you to have the front O2 sensor at least there and plugged in. I am not an expert by no means, but you have to have the evap and O2 sensor codes to show not reported, but still have the MIL light turned on. Your tune has all the front O2 codes still active, but the rear one not active. Go to the C6001 table and set all the front O2 sensor diagnostic enablers to 'not reported' and same with the evap codes. Also, make sure that the MIL is set to be illuminated in the C6002 tables for the appropriate codes. The way your cal is setup from what I can see it will never set the O2 monitors. The only thing I can see on the EVAP monitors is P0453 and P0453 enablers are still set to set a code after 2 trips. Again, I stress, I am not an expert with tuning, but this is what I can see may be a problem.
Also, here in WI, you are allowed to have 2 monitors not ready until model year 2000, after that you are only allowed 1 not set!!!
Hope this helps!!!

Thanks mike! I went through and checked the tune again. You are correct, the front O2's were showing 2trips. I will change them to Not reported, but all the MIL's are still active for all of the appropriate codes.
So, I set everything related to O2 stuff to Not reported, but MIL. So, this means that the "processor enabler" is set to "not reported" so its assuming its good to go, and then MIL active shows its "ready"? Thing is, all of my EVAP was set to "not reported" but all the MIL's still active, and it still showed up as "Not ready" during the inspection.

You are allowed 2 monitors to be set to not ready, so drive the thing after you fix your tune until 2 are not set and run through your inspection. We do that here in WI sometimes when you get old rusty beater cars that you know is going to throw an evap code or worse. Drive them until they just will pass the emissions test and then run them through, works 99% of the time!!
Good luck!!
