P051B Code---??

2012 Dodge Ram 3500 DRW 6.7 6-Speed Crew/Long Black

Changed oil for the first time yesterday at 4900 miles. The Change Oil indicator came on around 3000.

Today while driving home from work, the check engine light comes on and I was able to retrieve this code:

P051B-Crankcase Pressure Sensor Circuit Range/Performance

What does this mean?
How serious is this?
Do I have to take it to the dealer?
Can fix and clear on my own?
Any other info?

Thanks in advance guys!

You're under warranty. Unless you live a loooong ways from the dealer, take it back and have them make it right. A new truck shouldn't be throwing codes.

Oh, and unfortunately 4,000 mile oil changes are the norm on these trucks- despite what the manual says (unless you delete).

Sounds like someone didn't tighten the oil fill cap. Make sure it's on tight and clear the code.
