Ok on my code reader it pulled a P1401 code with a definition of Manufacturer Controlled Auxiliary Controller. Then in the DTC lookup it says Differential Press Feedback EGR Circuit High Input.
Little confused here, could anyone explain what this might be. Thanks.
 
Well guess no one wanted to help or knew. Figured it out on my own from some where else..........
