code p2290

[jrroyals02]

hey guys i think this is my second post but anyways i went on vacation down
to north Carolina with my family and about 30 miles in to the trip i rolled into gas and when i hit 80 the cel came on . The truck was running great no power loss and the temps were all good. so next time we stopped i check the code and it was p2290. i cleared it and off we went never came on for the rest of the 300mile trip.

ive been getting this code for awhile now but with no cel. just had the oil change and blue spring update. the only mods are gutted cat and sct sf3 tunes.

should i be worried about this or not?
thanks
