EGR Differential problem

[trdodd07]

I bought a new EGR Differential Pressure sensor and swapped it in for the old original one. Drove about 200mi and then I get a MIL lamp. Code is:

Fault 3383: Engine Exhaust Gas Recirculation (EGR) System - Data Valid But Above Normal Operating Range - Moderately Severe Level.

Is there a procedure I am supposed to follow to replace the Delta P, like a calibration in INSITE, or could it just be a faulty one? Figured it is just an easy remove, replace kind of deal. Made sure to remove the old O ring seals before I installed the new one with new seals.
