[s-cars] CC DTC Code question

[Nick Stuart]

Ah, I found this....

And it would explain why I found a mystery cable that had been
unplugged underneath the shroud that looks like it leads to a vacuum
line to this thing. I'm guessing that the PO had this opened, then
unplugged the line so it wouldn't close again. So how do I go about
reopening? Blowing or sucking?
