He grew up in both Räppe and Ör, since his parents were separated.[3] He joined Östers IF, made his senior debut in 1992 and joined Kongsvinger IL in 1997.[2] Here he scored ten Norwegian Premier League goals in 1997 and 1998.[1] In the middle of the season he left Kongsvinger for Austria Wien. He stayed here until 2000, when he returned to Öster.[2]
After retiring he became a youth coach. In 2009, he was promoted to assistant coach for the senior team.[4] In July 2010 he was promoted to head coach,[5] only to be replaced two months later - following a six-game losing streak - by Hans Gren.[6]
Another two months later, on November 10, it was announced that Ernstsson and Öster parted ways for the time being.[7]
