2005 mazda3 got p2188 code looked it up and found most common issue is purge valve. But also noticed one of the vacuum lines on the pressure sensor isn't connected/broken. Looked at the part number on it and can't find one online

The part number is 1s7g-9j559-bb
I keep finding the same part number but not ending in bb, I'm finding other letter combinations. What should I do?
