I dont think there is an XP reward for traps, at least nothing in the written rules.
I'd probably calculate CR like a monster with its offensive CR from its attack bonus or save DC as you would for a monster and its defensive CR with the disabling or spotting DC (whichever is higher) as the Armor class and its HP as 1 (since you only need to succeed on one check usually) and make that the XP reward. Maybe half the XP number if that seems to much for a single trap. (I am too close to going to bed to calculate some tests right now)

I'm away from book, but I belive you award xp for trap based on their deadliness. If I remember well, DMG has a table to determine the deadliness of a trap based on damage dealt. Then I assume that you allow xp as if they overcome an easy/medium/hard/deadly challeng for their appropriate level.
Again, I'm AFB and I'm writing this answer from Memory, which is not often the best ressources that I have

I don't recall seing any CR either, but someone could extrapolate that a trap that is considered a hard challenge for four level 5 characters grant as much xp to be equal 4x the xp a hard encounter would grant to a 5th level character. That would be my best guess on how giving xp for bypassing/removing a trap.

Thanks!!!
I'm calculating the XP for the introduction to my steampunk campaign, and it looks like there will be 6 "level-appropriate" encounters to get them from level 1 to level 2, and 8 "level-appropriate" encounters to get from level 2 to level 3.
There will be 6 PCs:
Aasimar brontomancer (homebrew thunder mage) wizard
Halfling Urchin Trickery domain cleric
Human (?) Archfey Pact warlock
Human (?) Sage Knowledge cleric 1/3pp Shadowmage X
Human (?) Sky Pirate (homebrew background) Swashbuckler rogue
(Wood?) Elf Path of the 4 Elements monk
