    Alright guys, I had a CEL on my 05 GXP kick on last week. It's P0521 Oil Pressure Sensor Performance.

    I took it to the dealer and they replaced the sensor. I drove the car home today and the same code came up as a CEL again.

    What else can throw the code if the sensor has been replaced?
