ok so i put my superchip back on my truck a couple hrs ago and after about 20 miles of driving i get slapped with a check engine light...pull over read the dtc and its P0096 (Intake Air Temperature Sensor 2 Circuit Range/Performance) so i switched from tow pref to mileage xs and cleared the dtc...and it went away...drove another 50 miles and it never came back...so my question is what does that dtc mean...should i be worried...could it have just been the tune (i went from stock to tow pref...got the check engine light....went to mileage xs and it was gone)

any info would help as im stupid when it comes to knowing what dtc REALLY mean
