B2252 is unrelated and a red herring.
The two current codes can both be set if the fuel is contaminated. Did you get a bad tank of gas?
0463 is also fuel related. Other experts may chime up but it may be worth running a botttle of Techron and see how you go.

Also threw this code, but do not not what it is
C2120 C- site says it is a TPM System Malfunction (No Sensors Received)

It means the computer is not seeing the output from the tire pressure monitors. Are you getting readings for tire pressure on the DIC?
You have a receiver in the car that picks up an RF signal from the sensors. The RFA is shared with the key fobs. Do your key fobs work OK? If so its not the receiver.
