Just noticed last night that my check engine light came on. I didn't get a pop up alarm on the display like I have in the past, so I can only assume it's not an urgent alarm. A quick Google search came up with this info in the following pic. I plan on calling the dealer, but I'd like to get a morning set in and they don't open for a few hours. Can anyone tell me how serious this is? I imagine it's just going to effect emissions, but again, I don't know.
