Greetings,
I took the Boxster out to stretch its legs on Sunday, and received an email from Allstate (I have the DriveWize thing in the car...I know, I know

) shortly thereafter that the car threw the Code P1691.
After some reading, it seems to indicate, possibly among other things, that the CEL bulb is out. If I turn the key to the accessory position however, the CEL does light up. I'm not sure what beyond the CEL bulb this fault might indicate.
Anything else I should be checking, and does it need to be addressed urgently?
