It might depend on how the code was removed. If you have a canned PCM from a reputable place you should be fine. If you are using a tuner though I think you have to be careful how you remove it. I am still just getting acquainted with tuning so someone correct me if I am wrong here. From what I've read there are two ways to deal with DTCs using a tuner. One way will just keep the light from coming on and when an emissions tester scans the car the DTC will still be there. The proper way is to set the PCM to not report the DTC. I did that with mine and recently passed my TX inspection without any issues.
