NC State Inspection caused Emissions message to appear??? S80

I replaced the Throttle unit with a used unit, 30K miles and very clean. Drove for 3 days with no errors. Took the car for the annual inspection and passed. The next day the "Emission Service required" message comes back. I wondered if the inspection, (they plug into your system to check for errors) could cause the message. I disconnected the battery for a few minutes. Now (6) days later all is good, no messages. Could this have been the North Carolina Inspection causing some temporary glitch?

thanks.

    Highly unlikely, and probably impossible for them to cause that light.

    The more likely scenario is that your car must complete a certain number of "drive cycles" in order for the internal emissions tests to complete. Once complete, if problems were detected, your light would come on. My guess is that your light will come on again, it's only a matter of time. In fact, you're lucky that NC seems to let cars through inspection without the internal "all tests completed" set. Some states will fail you, and make you continue to drive the around until the number of drive cycles have been completed.

      Thanks for the response. That makes sense because it did come back. Now I'll be replacing it again.
