Q: Check Engine Light on after changing oil - 2012 Kia Rio5

If starting it today was the first time after changing your oil, the oil filter and oil galleries were empty for a few seconds. If this is the case, the Check Engine Light is reflecting the lack of oil pressure while the oil pump fills the filter and gets oil to the engine and oil pressure sensor. The Check Engine Light should have gone off in a few seconds. If your engine oil ran 5 seconds or so without oil, it is unlikely to have ruined anything. However, if the Check Engine remains on, or the oil light on your instrument cluster comes on, get your engine inspected by a competent mechanic, like YourMechanic, who can address the oil issue before driving it further.
