I'm wondering if anyone has advice to fix these codes as these two codes keep popping up and the check engine light doesn't go away even after replacing the MAPsensor.

P0238 - Turbocharger/Supercharger Boost Sensor A Circuit High
P051D - Crankcase Pressure Sensor Circuit High

The codes are likely related. Here is what I need you to check first. The positive crankcase ventilation valve (PCV) hose or valve could be plugged, disconnected, or damaged. I need confirmation. Does this have a 2.4L turbo engine?

If it does, the PCV valve is under the intake. We may have to remove the intake to check it. See if you can gain access to it if you use a shop mirror.

Let me know.
