CEL - CODE - P051C

[PersianEcoBoost]

Getting Check Engine light and its from code P051C which is Crank Case Pressure Sensor Circuit Low. Asked a friend what this could be from and he said something with my MMR Intake and the sensor attached. Anyone else had this code before?

My Mods: Catback Exhaust, MMR Intake, TurboSmart BoV

Any help would be great before i start taking everything apart!

The connection from the valve cover to the intake tube sounds like it's not seated good. I'd take it loose at the valve cover and intake tube then reattach it starting at the intake tube then attach the valve cover. That'll ensure its got a good connection. There really shouldn't be anything else causing that issue.

I did what Juben said. I took off the engine cover to make sure the PCV valve was attached correctly. Everything looked fine. I cleared the code and the check engine light haven't come back. I will keep you updated.
