If you search rebrickable for 3040pb001 you get nothing despite the fact that this is an official LDraw part. The reason, I think, is that the set that it appears in isn't in the Rebrickable database and therefore the part has never been added. This also applies to new parts from new sets. They are listed on Bricklink no but not on Rebrickable.
Rebrickable is good tool and I'll probably update the script to use it but there are limitations.
That set is available on Rebrickable and the inventory leads me to this part: http://rebrickable.com/parts/3040p05
I think the reason you weren't able to find it with 3040pb001 is because the Bricklink number is listed as 3040pb01 on Rebrickable. It used to be that number in the past, but Bricklink changed all of their patterned part numbers last year. Like you can see here for the part in this case.
I actually stumbled upon this problem a little while ago, but then forgot about it again. Nice reminder!
I'll see if I can notify the admins at Rebrickable about this (relatively 'widespread') problem.
