Intake Air Temperature sensor voltage high/low. Check the wiring and harness and sensor. I am having the same problem right now with mine.

Of course you will still have it if you didn't do anything about it.. It won't magically disappear.
LOL I replaced the IAT sensor and it went away go figure?
23 came back today
It was a short!! it was in the wire harness just behind the connector plug I guess I wore it out connecting vac lines to the tee it was not visible to the eye the wire had broken down inside the coating.
