You should check the O2 Sensor. These little goodies control your air to fuel mixture. If these are in good shape and working proper. then check your wiring.

System to rich (Bank 2)
Code 52 means the system is compensating "full lean" because the oxygen sensor has been telling the ECU that the system is running rich and needs less fuel. This code comes up when the system can't take away anymore fuel (it has preset limits). It could be alot of things causing the problem, unfortunately I can't tell you any one thing to check.
