Codes Deleted/ How long until thrown codes cycle out. I had my codes deleted since I am running an ORY. I was told to wait 50 to 75 miles so my computer could cycle the old thrown codes out. I drove the car 60 miles and went to get it inspected and it didn't pass. I went to another place and the guy said if I would have had one more code pop up I wouldn't have passed. One that showed up was the O2 sensor heater I think and the other was an H-Vac code I think. Luckily I still passed, but I was just curious about the codes still showing up in the computer after they have been tuned out.
Thanks for the answers to come.

those are not trouble codes, those are the OBDII readiness tests (catalyst, o2's, heated o2's, evap., air, egr, etc..) I have noticed that it takes about 1-2 cold starts to get most of mine to complete and about 3-4 cold starts to complete the catalyst and heated o2 tests. There is a procedure on a website that explains how to complete all readiness tests on a GM vehicle but I noticed after about 4 days of normal driving mine were all completed.

Ok, so next year when I get it inspected will it be showing the same readiness codes? I don't completely understand. The guy that inspected said he was surprised that my check engine light wasn't on. Of course to myself I was like well that's because I had the codes deleted so the check engine light won't come on. But if they are not related then I am confused.

It depends on if they know what readyness tests need to be completed, or just if they are not completed it causes an issue.
If you have access to hpt or efilive the scanners will give the status of the IM tests, and it may be possible to adjust settings to alter this.

readiness tests are to verify that each part of your emission system is working properly. Once the computer has verified that a component is functioning properly it will give it a "complete". If you re-flashed your PCM then these tests reset and they have to be re-verified. Do a search, you will find all the info you need.
Also, if all your readiness tests were incomplete that doesn't necessarily mean that you should be setting an engine code, it just means the car has not have enough time to complete the readiness tests. The tech you talked to must be a little misinformed, he is probably seeing, catalyst "incomplete" and saying, oh, you should be getting some type of check engine light, but it has nothing to do with it.
a trouble code + an incomplete test means something is wrong.

I believe if you tune out all trouble codes that deal with that o2 sensors then the readiness code should go to complete, not just tuning out the SES light but the entire reporting. Also, don't worry, an incomplete readiness code will not make the car run any differently, I would worry more about the DTCs.
