DPFE sensor code P1401

[projectPONY]

This is the code I'm getting on a 2002 Ford Explorer. This is what I've been able to trace it down to.

Any thoughts?

Is this sensor something I can pick up at AZ?

More than likely the DPFE is at fault, could be a wiring issue as well but the sensors fail fairly regular. They should be available at any of the common parts stores. They may call it DPFE, EGR pressure sensor, exhaust pressure sensor.

Thanks, headed to parts store in a few.
