Error code will have to be cleared. The way that cars know when to turn on the check engine light is that there is a recurring error for "x" miles or time, as long as that error exists in it's memory most cars will continue displaying the check engine light.

Check for air leak into system after MAF.
vacuum leaks on intake manifold,
the air tube between the air filter.
intake manifold vacuum hose.
clean throttle plate with Berryman carburator cleaner
SEE sample picture HERE
Check for loose or no connected vacuum hose(s).
Take it for a test drive.

DPFE is a reasonable concern. There is also a very thin tube from the EGR to the DPFE that plugs up with carbon. Check the tube prior to the DPFE.

1st of all when Ford started out with putting "EGR's" on those diesel engines, they rushed it and are nothing less than a pain in the ***! i recommend having an EGR cleaning service performed by your local Ford dealer, i know they charge up the wazoo, but they're the best people to perform the service period.this is a VERY common problem with those engines and that service is "supposed" to be performed every 30K I believe. i dont recommend attempting to remove and service it youself, this WILL only make it worse.
