Your question is to vague to really answer.
My three best guesses at what your question is:
Q: Why did my computer codes not reset after a repair to the component that tripped the code?
A: Codes must first be cleared with an OBDII scanner and the computer needs to retest the component, if it's in working order the code will not return.
Q: I unhooked my battery but the computer didn't reset?
A: Vehicle CPU's are equipped with an internal power source to sustain them during battery replacement or random battery death as well as to prevent people from making inspection failing codes from vanishing just long enough to get through inspection.
Q: I deleted a code after repair but still failed inspection because the computer did not reset?
A: With many parts that will set off the CE light the computer does what it needs to do with the information, some components have requirements in order to engage and send that information. Until the computer has that information it displays what is called a monitor. This monitor tells the inspector that the the computer was either recently was cleared and the CE light could come back on at any time. In NY an active monitor on any emissions component will fail inspection, even a lick-it stick-it guy I used to take my beaters to would not pass a vehicle with an active monitor until after he failed it once. If you have an active monitor, you have to take the truck out and drive it a bit, drive through the city, hit the high way for a bit. Put a couple hundred miles onto it and recheck your computer.

I took to get inspected they said the computer was not reset they said I had batt unhook but we have not.only thing is we had a throttle body put on it.
I do not and have not got any check engine lite at anythime.
when they try to inspect it they say lot of the test is incomplete.told me to unhook batt run for 200mile. I done that still will not reset.

Yeah, that would be a lot easier on us. Take the truck down to Autozone or where ever you have, they usually will scan your vehicle free of charge, they will tell you what active monitors are on the vehicle.
