That is the time to change oil code. They will reset when you get it changed, if not take it back and remind them. I assume you are not doing it yourself if you don't recognize the code. I'm a mechanic and I don't change my own oil either, it's cheaper to have them do it, just don't fall for the extra stuff they tell you that you need. Check out what they tell you first then decide if it's needed

Code 82 is crank shaft position sensor circuit
replace the sensor
