Engine light

[Callouse_Savage]

So last night I changed my Oil Filter Housing with a new Aluminium one, check engine light went off as well as no more oil leaks, but during a test drive last night, the check engine light came back on and now I have 2 codes, PO6DD, PO520. both say it is the sensors on the back of the housing but they are new. Oil pressure won't go above 30PSI. Any thoughts of what it might be would be greatly appreciative

OEM or aftermarket sensors? Re-install the original sensors and see what happens
