Anybody know about Honda CR-Vs?

I have a 2006 Honda CR-V. Last week, the check engine light came on so I went and got that fixed. After a few days of the check engine light being on and prior to me going to the shop, my VSA light came on and the triangle with the warning sign. I took it to the Honda dealership and they said if I change my oil that will fix my issues. For some reason, he said the lights will remain on for about 3-4 days before they reset. Does anyone know if he is right when he said that? Anyone have the same issue? Thanks!
